I think you got the direction of travel for the DCC++ command wrong.
In DCC++ 1 is forward and 0 is reverse I know.
In Loconet 1is reverse and 0 is forward I think.

So line 389 in IoTT_SerInjector.cpp should be something like:

sprintf(txMsg, "<t 1 %i %i %i>", cabAddr, transmitQueue[hlpQuePtr].lnData[4], !((transmitQueue[hlpQuePtr].lnData[5] & 0x20))>>5); //[4]: SPD, [5]:DIRF

Then I don't know if you got the speed steps right for DCC++ as in DCC++ the speed steps are from 0 to 126 and -1 is emergency stop. Does that match wit inData[4]?

new macOS installations use \n as the newline character not the \r this causes, python to look at the wrong file names.

https://stackoverflow.com/questions/3821784/whats-the-difference-between-n-and-r-n

There was also something else with PySerial not being installed and Python bugging out during the install but I do not feel it's in the realm of your project to fix nor care.

When on the individual tabs and pressing 'Save to File', it would be nice if the default file names was not IoTTConfig.json and was something specific to the tab like IoTTConfig-led.json, IoTTConfig-rh.json, etc.

A URL or REST API that can be called by curl or wget to download the IoTTConfig.json.

Hello!

For some reason, I am unable to connect to the Purplehat HTML page (Firmware 1.5.12). It was working until the battery in my IOTT stick died while in use; I let it charge via a phone charger (plugged into the wall) for about 1 hour and then rebooted the stick.

The stick is able to show all data on the display, and it connects to WiThrottle. I can navigate to the main page and the Withrottle page without issues. However, when I try to load the Purplehat tab, the page never loads. I've attached a video:
https://user-images.githubusercontent.com/2058763/168412874-2f842f87-973e-4f7c-8350-6cce5a5e260d.mp4

This happens on mobile, Edge, and Firefox. Here's a video of Firefox; it appears to hang when fetching PurpleHat.js:
https://user-images.githubusercontent.com/2058763/168413120-a5d2881e-345f-44d9-974d-fefd85167c2e.mp4

I am constantly leaving my purple hat configuration on and returning to a dead battery the next day.

If you could add a popup after a time of no user input to the website when the user does not respond it shuts the M5 down. Or
There could just be a time out field that is user selectable to shut the M5 down.

Today I had to reinstall the software on the M5 because the purple hat tab would not open after the loss of battery power.
I'm old so I don't think I can change. lol.

Hi Hans,
I just tried to build the project in the Arduino IDE using the latest ESP32 core version 2.0.3 and found it wouldn't build.

I tried version 2.0.2 and it still failed so dropped back to 1.0.6 (last of the previous major version) and the build completed - albeit with a bunch of warnings.

I wonder if it might be useful to state in the README.md file the version of the ESP32 core used for the release build so others can be confident of reproducing your set of build files

Alex

According to your schematics for the Loconet communication board, I have created an adjusted one. Since I do need only the Loconet communication and no separate loconet.
However I have forgotten to connect pins 2 and 5 of the loconet RJ45 connector.
For that I have created a wire bridge between the pin 5 and RXD.
But at my DCC command station Digikeijs DR5000 the Loconet led TX keeps active. And I don't seem to have any proper loconet communication between the command station and my breakout board. I do not receive any commands on ESP32, and commands from ESP32 don't end up at the command station.

Can you please help me out? Thanks.

This is my schematic:
ESP32 loconet breakout board.pdf

I am trying to order a few loconet boards from jlcpcb. The components are placed at an offset in the preview. It says that jlcpcb will adjust the placement, but since this is my first time trying to use jlcpcb i am unsure if this is a normal offset or if I did something wrong.
Does the attached picture look like it does when you order pcbs?

When saving to file from the Configuration tab, the json file saved does not have any of the nodes config in it.

The 'Save to File' button on the 'LN TCP Client' tab does nothing when pressed.

IoTT 1.6.5

When using IoTT WiThrottle server, pressing F10 or higher restarts the IoTT stick

Current setup:
Arduino Mega DCC-EX 5.0.6
IoTT stick 1.6.5
IoTT Redhat
IoTT Power Shield
Engine Driver on Samsung S8

• I turn on WiThrottle on the Redhat and connect with Engine Driver.
• I select one loco from EngineDriver.
• I can activate functions F0-F9.
• I press F10 or higher.
• I see the screen of the M5 stick restart
• Engine driver loses connection with the stick.

Firmware Version: 1.6.3
Connection Type: WiThrottle Client
HAT: PurpleHat
Browser: Firefox
OS: Ubuntu

Am trying to run the speed matching tool on my stick, however for some reason I get a web socket timeout right before it completes the testing.

If I do a calibration using a max speed of 10km/h, 10 speed steps, 10 throttle steps - it loads ok.

If I do the same calibration using values of 80kmh, 80 speed steps, 126 throttle steps (NCE) - it times out at the very end (screenshot below)

Looking in the web developer console I see the web socket connection close, and the bottom panel (with the blue graph) doesn't load.

Any ideas what may be causing it?

For the Windows version esptool.exe addresses the executable. The way update.bat is implemented esptool must be in the path. Removing the ".exe" extension makes the batch-file directly usable for Linux. Please remove ".exe"in a future version.

I'm trying to connect my Purplehat to a WiThrottle server, running IOTT Stick firmware version V1.5.19 (latest). However, I've noticed I'm having issues trying to run the speed profiler.

Below, you can see that Purplehat has a connection to my WiThrottle server - the IOTT stick has the IP address 192.168.45.2. However, you can also see that despite having a JMRI roster entry loaded the DCC address is still "n/a".

I can't seem to do anything to get it to respond or manually set the roster entry, either (I don't have a Loconet system to connect to).

Additionally - and maybe this is unrelated - the IOTT stick itself is not responding to the power button being held down. I can still cycle through the screens with the "main" button and I can still restart the stick from the web interface (restarting in the web UI doesn't seem to help at all, but I can see the uptime reset). It appears I'll have to wait for the battery to drain to turn the stick off and try again.

Option in node config to optionally add the Node Name to the file IoTTConfig.json name. IoTTConfig-.json

eg. IoTTConfig-myGreenhat.json

This is handy if you have many IoTT to manage.

When trying to add another "THEN THAT" action to "Individual Color" enabled LED, the + button adds blank row.

Reproduction:

1. Set multiple LED # (eg, 0,1)
2. Choose type that supports adding multiple commands (Analog Value or DCC Signal)
3. Enable "Individual Colors"
4. In "THEN THAT" column, click the + button to add another row.

This will add a blank row. Sort of.

Further testing show that the row was added, but not shown. If you click the + button a few more times, then toggle the "Individual Colors" box off then back on, you will see all the rows you added.

Also, if you have multiple rows (eg. 10) and click on the + at row 1, all the rows below are hidden. Again goggle to make appear again.

Tested with 1.5.18 in Blue Hat mode. Possibly same in other HAT modes.

With 1.6.7, the RedHat I found frozen after a few days. Not sure if there is a memory leak. If I reset, it will happen again after a few days. I'm going to leave it on the uptime screen to get exact time next time it stops.

To help, can a new screen be added to the LED panel with the following?

• uptime (moved from battery/power screen)
• stick temp (moved from battery/power screen)
• Available RAM/Flash
• Date / Time:

This also leaves all the battery and power alone on one screen.

Hi,

First let me say that I really like what you are doing pushing the envelope on train communications. I have watched most of your videos and appreciate the level of content and thoroughness that you approach every topic.

I was able to get IoTTStick running on an AI Thinker ESP32-cam. I ran into an issue that I believe I have run into before which is that an ESP32 will connect to the first AP that allows association, but may not be open. This fools the ESP32 into thinking it has a good connection when it doesn't. Yes, it has dhcp'd successfully, but can't pass packets.

Even if the ESP32 is successful and connects to an open AP, the question, in crowded areas, is which one? The associated AP's SSID doesn't seem to be documented/announced anywhere, or maybe I missed it?

I'm sure you can see where I'm going. With the current Wifi config hierarchy of client, AP, Client+AP, it is easy to get stuck as a client to a wrong AP.

I believe it would be a best practice to always first-boot into AP mode and allow the user to set preferences and credentials.

I hope you find this of help.

Best,

Mike

This is same content as email. Just better here for tracking.

When using IoTT WiThrottle server, adding a second locomotive to a consist crashes the redhat.

Current setup:
Arduino Mega DCC-EX 5.0.6
IoTT stick 1.6.4
IoTT Redhat
IoTT Power Shield
Engine Driver on Samsung S8

• I turn on WiThrottle on the Redhat and connect with Engine Driver.
• I select one loco from EngiveDriver and I can turn on and off the light and move the train.
• I now try to add a second loco in consist.
• Engine Driver seems ok
• I see the screen of the M5 stick restart
• Engine driver loses connection with the stick.

Settings in the LED chain are getting last after save and restart when 'Individual Colors' is chosen. I enter all this data.

then, when I press save and restart, this is what it changes to.

As seen, the UI has set them all to "Select LED 1" and many colors setting are blank.

Stranger still, when I test it with JMRI, it only wants to change LED 2 in my neopixel even though the UI only ended to with LED 1 settings.
