Hi

I'm trying to follow your documentation on how to configure it with TTN but It's not enought detailesd:

The Application EUI is by default set to 00..00, you need to change this to anything else to be able to configure your WioLoRaWanFieldTester.

How do I change that in the Wio ? does it mean I have to recompile your code with my own AppEUI ?

Thanks

Vincèn

Is it possible to change the Seeed bundle to your own Helium DEVEUI and keys?

The serial commands do not appear to work?

Apologies if this is a FAQ - but could not find info.

I just noticed that the helium hotspots being deployed with AS923_2 is somehow using AS923_1 freq. I'm currently asking about it in helium/poc-discussion discord.

It's possible there's a bug in AS923 implementation, but don't know comes from helium code or from the manufacturers. Cause both Linxdot & Sensecaps can witness each other here, but under AS923_1 freq channel (which isn't supposed to be). They should be using AS923_2 freq instead.

Can you confirm that the AS923 freq channel (for region 1,2,34) inside the wiolorawanfieldtester code is using this frequency listed here? https://github.com/helium/miner/blob/0bb8841fbeb1051820691d1f39d4e596fe9d5dfd/test/miner_poc_v11_vars.hrl#L58

Dear Paul,

I've tried to upload your code using ArduinoIDE. After updating the library, finally stucked on the Flashstorage.cpp error.
Is there a way to overcome this?
I've tried board manager for Seeed Wio terminal from board manager version 1.8.2 and 1.8.1. Both failed on this Flashstorage.cpp error.
Here is the error:

Hi, It is possible to customize the logo that appear on splash. I do not know how obtain "*ttn_data" (https://github.com/disk91/WioLoRaWANFieldTester/blob/master/ttn_logo.h) from an image.

'SERIALE5' was not declared in this scope

Hi

Just got a Wio Tracker Lora kit but I'm quite confused if it needs to be updated. It states version 1.5 for E5 when it boots on the Wio. I have seen some 1.8 version here. Is it a good idea to update ? Should I also before flashing 1.8 load the fw to clear E5 configuration ? or can I flash straight 1.8 version ?

Thanks

Vincèn

I noticed on these two lines:
https://github.com/disk91/WioLoRaWANFieldTester/blob/master/LoRaComE5.cpp#L273
https://github.com/disk91/WioLoRaWANFieldTester/blob/master/LoRaComE5.cpp#L344

They are looping over all 72 channels and calling AT+CH=chn,OFF to disable channels.

An alternate way of doing it (in a single AT command) is by calling AT+CH=NUM, from-to, eg AT+CH=NUM, 8-15.
This enables 8-15 and disables all other channels.

7x less AT commands isn't going to make a huge difference, but every bit helps.

Hi, just found out about this great solution for testing the lora network.
Can the code be used for AS923 frequency?
I'm currently ordering the Wio Terminal with the lora gps module, just waiting for the shipment.
But i can't find the option for 923 freq. Or can i use the US915 code for AS923? And if that's possible, what kind of changes needed to be edited?

Hello,

Im interested in knowing what the default output of the metrics are? IE: when it sends the data payload off to a console like helium console, is it sending the payload in JSON? I want to be able to use my own backend server if possible

Thank you!

I am having trouble decoding data on DataCake

I have it set up on TTN which works great and have set up an integration with DataCake - I tried your decoder from your instructions with DataCake but don't get any correct values for any decoded values. My integration webhook URL from TTN is https://api.datacake.co/integrations/lorawan/tti

Here is the decoder I am using:

`
function Decoder(bytes, port) {
var decoded = {};
// avoid sending Downlink ACK to integration (Cargo)
if (port === 1) {
var lonSign = (bytes[0]>>7) & 0x01 ? -1 : 1;
var latSign = (bytes[0]>>6) & 0x01 ? -1 : 1;

var encLat = ((bytes[0] & 0x3f)<<17)+
             (bytes[1]<<9)+
             (bytes[2]<<1)+
             (bytes[3]>>7);

var encLon = ((bytes[3] & 0x7f)<<16)+
             (bytes[4]<<8)+
             bytes[5];

var hdop = bytes[8]/10;
var sats = bytes[9];

var maxHdop = 2;
var minSats = 5;

// if ((hdop < maxHdop) && (sats >= minSats)) {
// Send only acceptable quality of position to mappers
decoded.latitude = latSign * (encLat * 108 + 53) / 10000000;
decoded.longitude = lonSign * (encLon * 215 + 107) / 10000000;
decoded.altitude = ((bytes[6]<<8)+bytes[7])-1000;
decoded.accuracy = (hdop*5+5)/10
decoded.hdop = hdop;
decoded.sats = sats;
// } else {
// decoded.error = "Need more GPS precision (hdop must be <"+maxHdop+
" & sats must be >= "+minSats+") current hdop: "+hdop+" & sats:"+sats;
// }
return decoded;
}
return null;
}
`

I get something that looks like this when debugging in DataCake:

{ "accuracy": 0.5, "altitude": -1000, "hdop": 0, "latitude": 5.3e-06, "longitude": 1.07e-05, "sats": 0 }

Hello. I bought the WiO terminal from seed preconfigured.

I accidentally chose the wrong region on first boot.

I tried to send Z=US915 after the device is on, but I only receive a response of "Busy" from the terminal.

Is there another way to change the zone after the terminal is configured?

Are there plans for AU915 support?

Hi,

This is more like a question, not sure if github issue is the best way to, maybe on Discord...

So, retry in case of a normal sensor is totally sensible, but in case of a mapper - since it's moving - the retry can be from a pretty different location. Especially at SF12 it's over two minutes. So I think retry is actually harmful. Of course, one can set it to 0 :)

But removing retry would free up a button: One idea is single click - turn off the screen (to save battery), OK haven't yet measured, but could help if running from a smaller battery. Long press - lock the controls (for example the mapper is in a backpack or bag).

BTW, do you have a HNT address for donations / "thank you"? :)

Hello,

I've tried everything to get a WIO tester working with TTN Australia without success, and I hope someone will be able to tell me where I've gone wrong.

The consistent error message is "MIC Mismatch"

The DevEUI and the AppEUI are correct. Is the field "SerialNumber" when the device connects over USB the AppKey? If not, how can the AppKEY be queried? It appears as just Xs on the configuration seen and I don't seem to be able to set it with a serial console application.

Hi,

I've followed the instructions exactly, but FlashStorage.cpp doesn't compile on SAMD51 platforms (Wio Terminal) because the defilnition NVMCTRL->CTRLB.bit.MANW is missing. Tested with Wio development environment 1.8.2, 1.8.1, 1.7.9 on Windows and OSX (clean install). Did I miss something?

Hi, I am trying to compile the software in Arduino. When I set the Role to Slave, I generate the binaries but Arduino´s Software return me this error:

"
collect2.exe: error: ld returned 1 exit status
Error compiling for Seeeduino Wio Terminal board.
"

This is my configuration on Tools

Thanks!

Clear the downlink queue from the backend server. This avoid to have a long dequeuing of previous tests when the device was not able to receive the downlink but able to communicate with uplinks.
Can be done on new session if we do not want to loose some downlinks during one session or can be done for each new downlink considering missed downlink are not interesting at all (faster)

Hi, WioLoRaWANFieldTester can be configurated on ChirpStack and get GPS data on this software?

Would it be possible to have an option to immediately delete discovery mode results and not to wait the 2hrs?
It would be nice to have for testing 2 different antennas back to back.

Hi is there a way to reset the seeed bundle?
I think I broke it.... Didn't know nothing should be done but I watched video and did the steps and Im getting black screen, then I troubleshoot and installed the GPS file to "reset" and i'm seeing
"Verifying setup"
"Setup Ok, nothing to do"

Please advise and appreciate all the help :D

Since mappers migrated to v2, 2 things needs to be updated:
(see https://docs.helium.com/use-the-network/coverage-mapping/mappers-api/#ingest-uplink)

• Injest URL needs to be updated to production one
• hdop & sats seems not to be anymore used. Instead we need to transmit accuracy field

This requeires change in:

• README.md to update the self mapping function
• disk91's backend to use new format (behind https://dev.disk91.com/fieldtester/helium/v3)
• and maybe the radio protocol (as i'm not sure we already get the accuracy information)

Mappers v2 announcement: https://discord.com/channels/404106811252408320/730418759298318346/859580354792390666

It would be great if the screen naturally turned off after 5-10 minutes of no button presses, then turned back on when you press a button.

This setting could be enable by either:

• a config setting in the code (set at compile-time)
• a setting accessible on the device via the buttons, perhaps on a new "Settings" page

The screen uses energy and is very bright when there is no ambient light, so it would be much nicer if it didn't use power to be so intrusive.

Using the Seeed kit I am trying to get the unit set up on TTN. I do not get any serial response (OSX Serial2, 9600.8.N.1), I can connect to /dev/tty.usbmodem113201 however there is never any output either from typing or on bootup. The blue light flashes when I type. Is this the right way to get/set the AppKey? Firmware 1.9, WioLoRaWANFieldTester_LoRaE5_ALLZONE.uf2

Hello!
I buyed a WioTerminal and a Lorawan module for it, i installed the latest WioLoRaWANFieldTester_LoRaE5_ALLZONE.uf2 (v1.6) but the GPS always red, theres no Latitude or Longtitude value (only 0.00000).
I use it without the battery extension. Is there any fix for this issue?

I got the Seeed Wio bundle a while back and thought it was time for a firmware update. I flashed 1.9 (LoRaE5) to the Wio and now it simply hangs at the startup screen ("Wio LoRaWan Field Tester / Version v1.9 (LoRaE5) / WIO_FT_XXXXXXXXXX"). On the LoRa section there's a steady blue light and blinking red light. Any idea what might be going on?

I've got enough experience with embedded systems and the like to suspect the power issue, so I connected it to a power supply with plenty of current to spare and it still does the same thing.

You have probably been asked this before but i need some clarification.

1. I need to set the Application key on the device to get it to connect. When i look in the setup it is x'd out.
   I can set it using putty commands direct to the module but, when power is removed this does not save.
2. We are using AU915 and it always defaults to sub band 1. We use sub band 8 for most instances.
   As with the application key i can set the frequency band via direct putty commands to the module and then it works.
   Again though when power is removed, the unit defaults. Is there a way i can write the commands i want into the unit and have them
   stay there?

Why duty-cycle after Tx on "Max Rate" is always 144s?

Does Discovery mode support TTN? Or does it only support Helium?
When I use Discovery mode in the TTN environment.The link in the QR code cannot be accessed from a mobile phone or computer.

Any help would be appreciated.

This is the first time I am ever posting an issue, appolagies if this is not the right place.
I have a had a field tester fro some time and have recently questioned if I have GPS, is there an easy way to check and was there an option on purchase to take a non GPS version. I did think I took the full version and if not thats ok, just want to check.

Tack / Thank you

Hi, Where can I change the time to refresh GPS position? And UI?

This could allows to uses these IDs in the console instead of using console IDs for the device.

Need to update the display screen to support negative SNR

Hello,

i got the Seeed Package. After Updating to newest Firmware, The Device keeps booting in bootloader mode. I tried reinstalling firmware without success.

The max tx power set up in the wio terminal for AS923 is 16dBm. This shouldn't be limited at 16dBm as some countries in AS923 region may have different regulated EIRP.
For example, 26dBm is the regulated EIRP in Indonesia. So if WIO max tx is set as 16dBm, even an 8dbi antenna wouldn't be able to achieve the max EIRP. Even 10 dBi antenna wouldn't too with the reduction in cable loss.
Can the max tx power for WIO for this purpose (yours and seeed version) be revised to 22 dBm for AS923? Since some people may use the stock antenna that come with the LORA/GPS module from Seeed for the WIO terminal (i believe it is only 1.2 dBi. never got the clear answer from Seeedstudio).

I want the device to show that a firmware update is available, when applicable. This can be done by either of the following two options (or both):

• the device sends its firmware version with each packet to the server, and then the server sends back a bit that says whether a new version is available
• the server sends, with each packet, a "latest version" data structure, which the device compares to its internal version number

It would be helpful to get feedback about when an update is available. I think it would also be a nice demonstration of how this sort of feedback is possible/easy to implement via LoRaWAN communication.

referencing to #62

we'd like to request the option to select sub-band for AU915 and US915.

US915 -

Sub-Band 1 | 902.3 - 903.7 | 0-7
Sub-Band 2 | 903.9 - 905.3 | 8-15
Sub-Band 3 | 905.5 - 906.9 | 16-23
Sub-Band 4 | 907.1 - 908.5 | 24-31
Sub-Band 5 | 908.7 - 910.1 | 32-39
Sub-Band 6 | 910.3 - 911.7 | 40-47
Sub-Band 7 | 911.9 - 913.3 | 48-55
Sub-Band 8 | 913.5 - 914.9 | 56-63

Downlink sub-bands | Frequency range (MHz) | Channels
Downlink sub-band | 903 - 914.2 | 64-71

(reference: https://www.baranidesign.com/faq-articles/2019/4/23/lorawan-usa-frequencies-channels-and-sub-bands-for-iot-devices)

Decoder functions are useful in the Helium Console, as they are functions that allow the decoded payload data to be sent to the HTTP endpoint.

Please use this guide to write a decoder function for others to use.

I have wio-terminal with the E5 Lorawan module. The device does not boot after I drag the E5 .u2f over to the wio-terminal drive.
The RFM version will boot, but obviously lorawan won't work because it's not the correct module.

Hi,
I just got a Seeed Wio Terminal LoRa-E5 and GNSS Chassis from Digikey.
I flashed it using the V1.6 WioLoRaWANFieldTester_LoRaE5_ALLZONE.uf2 firmware.
I configured the frequency (US915) and the DevEui, AppEui, and AppKey.

I get LoRaWan configuration OK, but when the program restarts I get a "LoRa board is missing".
Seeed support doesn't seem to know how to debug this problem.
Can you help me?

Thanks,
Ralph

Hi
i recently received my WIO Field tester, i configured it to AS923_4
but it docent seem to connect to any Helium Miner although i got 3 miners installed all around my house
i did manage to see some connectivity since when i watched for it on https://cargo.helium.com/ i noticed its signal
but on the device it self, i don't get any signal noticed in any of the screens ,
on the status area i get only "Lost"

can it be issue of AS923_4 region , which isnt supported? , or do i have to configure something, on the device?
i even tryed upgrading to ver 1.6 ...

thanks
Tzach

Hi there

we'd like to use the field tester with Kerlink WMC and TTI

We have the SEEED bundle.

Can we get the appKey and just add them to our network servers? Or do we need to flash different firmware?

Also, where do we get the appKey per-defined in the seeed bundle?

thanks alot!

The first shown value is the oldest value, the others are in the right order in the graphical display

I have tried two different chips, and checked the pinout many times, and continue to get this error. Are these boards incompatible for some reason?

Received field tester from Seed Studio. It worked fine for about 1 month and the screen stopped working. Both lights are on when connected to a usb c power cord. Here was the email that I received from Seed Studio.

I see that the blue light of your device is flashing quickly. You can quickly dial the power button on the left twice to make the device enter the Bootloader mode, and then dial it again to exit the bootloader mode, and the device should be restored to normal.

If the firmware is still not displayed, please try to refresh the firmware according to this wiki. Remember to remove the Lorawan expansion board when refreshing the firmware and refresh wiO Terminal only.

When I use Audruino and try to select port with terminal I get this msg.

Programmer not responding. Make sure that the firmwareupdater sketch is loaded on the board.

Any help would be appreciated.

Hi,

Happened a couple of times, that the field tester did join, did get GPS lock, did transfer packets, so work as expected but after some time it looks completely frozen. No response to any of the buttons.
In all occasions it's frozen displaying "TX 06" in the status area.
Settings: +14dBm (or +8dBm, tried lower tx power to check if it might be some power supply glitch?), SF07, retry 1, max rate. Powered by power bank, or car's USB port. DIY version, PCB from Seeed, hand soldered, RFM & GPS populated, no battery charger circuit. No enclosure, so could be random ESD event, but it always hangs at the same state. Flashed with WioLoRaWANFieldTester_EU868_GPS.uf2
And does work again after manually resetting.

Any idea what might be wrong? Or how to troubleshoot? I see some debug statements (like LOGLN) in the code, would those log to USB serial?

I have edited keys.h with my DevEUI, AppEUI, and AppKey. When I compiled the code I'm getting this error message.

'exit status 1 'processLoRaConfig' was not declared in this scope'

It compiled perfectly and Wio is working properly once I Commented out the following lines of code.

// Make sure the LoraWan configuration has been made if not wait for the configuration boolean zero = true; for ( int i = 0 ; i < 8 ; i++ ) { if ( loraConf.deveui[i] != 0 ) zero = false; } if ( zero ) { configPending(); while (true) { processLoRaConfig(); } }

As well as commenting out the following code in keys.h
