I'd like to see the functionality for sending and receiving HTTP requests.

Something the allows for sending basic HTTP GET requests and get responses back. Eventually an abstraction for other HTTP methods, as well as abilities to post multipart-form data, apply headers for authorization, and json bodied requests.

When I run the ThingSpeak.py file from sample folder, I get the following error.

AttributeError: 'CellularIoTApp' object has no attribute 'sendDataComm'

I have checked the cellulariot.py file and 'sendDataComm' method is not defined

Please help

Data module is not working, please advise what are the steps do debug it / fix it.

Thank yoy

Hi i have problem with this cos. So i have failure on sending AT commands:

Traceback (most recent call last):
File "/usr/lib/python3/dist-packages/serial/serialposix.py", line 275, in open
self.fd = os.open(self.portstr, os.O_RDWR|os.O_NOCTTY|os.O_NONBLOCK)
PermissionError: [Errno 13] Permission denied: '/dev/ttyS0'

During handling of the above exception, another exception occurred:

I dont know what it is I configure my modem to IP adress of RPI: 10.0.0.2
Port:5000.

PLEASE HELP ME !
I cant send any AT command to mi BG96.

Hello,

I'm following the tutorial for the Cellular IoT HAT UDP.
When i launch the basicUDP.py script, it stops at this operation :

Modem configuration : GSM_MODE Trying to connect base station of operator... AT+CGATT? AT+CGATT? AT+CGATT? AT+CGATT? AT+CGATT?

I have connected my HAT to a Raspberry PI 3 model B. My laptop is connected to the internet with WiFi. The Pi is connected to my laptop with an Ethernet cable. I have shared the connection of the Wifi with the ethernet.

I think the problem is the port forwarding. The IP address of my PC is 192.168.1.XX/24 so I port forward this IP. Although, the IP address of the PI is 192.168.137.XX/24. I don't know if this is correct or not.

PS: for my application, i cannot directly plug the PI with the rooter. Now my laptop IP is 192.168.1.46 and the raspberry IP is 192.168.1.47

Do you have any idea to solve this problem ?

Edit : I'm now able to have an IP of my router network for the PI but it still doesn't work at the same step.

Hi,

I have successfully run the sensor test on a fresh install of Raspbian Buster
Linux raspberrypi 4.19.57-v7+ #1244 SMP Thu Jul 4 18:45:25 BST 2019 armv7l GNU/Linux
Description: Raspbian GNU/Linux 10 (buster)
Python 3.7.3

But when I have tried to run on Stretch and then Stretch upgraded to Raspbian Buster 10.3, running the sensor_test.py causes the Pi to shutdown.

(I have a 3A PSU)

Do you have any suggestions as to what I should check in my OS settings

I am trying to connect the shield via USB but Its not responding is there any extra step for it cause I was not able to find anything. Also I tried sending SMS when connected to GPIO/UART. It is unable to send SMS. The code flow is as follows
sudo python3 Sixfab_RPi_CellularIoT_App_Shield/sample/sendSMS.py

hello world!

I have tried to use the sample codes given in sample folder. none of them is working except 'sensor_test.py'
the AT commands repeat themselves on the terminal.
can i use some AT commands without using the sim?

I'm having problems initialising GNSS on the Hat.

My code is here:

  node = cellulariot.CellularIoTApp()
  node.setupGPIO()
  time.sleep(1)
  node.turnOnGNSS()
  time.sleep(30)
  node.disable()
  time.sleep(1)
  node.enable()

When I interrupt it, the stack trace is here:

  File "src/cosmic_test.py", line 73, in <module>
    main()
  File "src/cosmic_test.py", line 42, in main
    sixfab_sensors.init()
  File "/home/pi/cosmic-pi/src/sixfab_sensors.py", line 10, in init
    node.turnOnGNSS()
  File "/usr/local/lib/python3.7/dist-packages/sixfab_cellulariot-1.2.0-py3.7.egg/cellulariot/cellulariot.py", line 421, in turnOnGNSS

  File "/usr/local/lib/python3.7/dist-packages/sixfab_cellulariot-1.2.0-py3.7.egg/cellulariot/cellulariot.py", line 30, in millis

I have the antenna plugged in, I am testing it outside, under cloudless sky and I have a SIM card inserted.

Should I be checking satellite coverage for my area, or is there something else I need to do or a way of checking?

I'd like to use this modem in conjunction with a PiJuice hat, but I'm running into a conflict on GPIO 17.

It appears that the PiJuice hat relies on GPIO 17 to be 3v3. So, when I run node.enable() this effectively does GPIO.output(17,0), which interrupts the power supply and restarts the Pi.

Do you think there's a way around this? Is there a way to set the modem to use BG96_ENABLE = 18 for example or is that locked in at the hardware level?

This may indicate that I did not install cellulariot.py - I believe I obeyed the instructions as written.

Thoughts?

Following this tutorial, https://www.twilio.com/docs/iot/supersim/getting-started-super-sim-raspberry-pi-sixfab-cellular-iot-hat#appendix-downgrading-the-pi-kernel

When I run the python3 sample/configureCATM1.py command, nothing happens.

The thing runs forever, the blue network light is flashing and everything else seems fine.

Also, my stats on Twilio SuperSim are going up as if something is actually happening.

I'm never even getting to see the "Waiting time:" prompt or anything else. I live in a crowded US town with great coverage.

Thanks!

Is there an equivalent of class CellularIoTApp(CellularIoT) for the Sixfab 3g/4g HAT?

Hey,i am trying to connect a nb sim supporting IPV4-V6 with the nb configuration but it is not possible.But when i am using GSM configuration for the same sim everything works fine.
Any thoughts?

Hello,

I have since October 2018 a Sixfab IoT shield. I have been able to connect shield to raspberry pi with PPP, and get IP adress in Rasapberry Pi, being able to control remotely a robot connected to this raspberry pi through Sixfab shield. I am able to read with python sensors in shield, but when I try to send AT commands from raspberry pi using python to IoT shield to get RSRP, I am getting an error like one below:

from cellulariot import cellulariot

Now I am trying to connect Sixfab with Raspberry Pi through USB cable, using usb connection in IoT shield, and one out of four usb ports in raspberry pi, but I do not know how to get usb port in /dev directory of raspberry pi. I am able to connect IoT shield to windows computer through usb cable, and opening a putty serial console I can reach serial port of IoT shield and send AT commands and receive results from IoT shield. At this point I have connected Iot shield with raspberry pi only through usb cable, without insert Iot shield on 40 pins connection of raspberry pi.

I guess that I need drivers in raspberry pi in order to permit to Pi read serial port through usb, but following PDF Quectel_WCDMA&LTE_Linux_USB_Driver_User_Guide_V1.8.pdf is confusing for me since I do not know how to download kernel files.

Please, could you give me some clue about how to follow with this config and be able to connect Pi and Shield through usb serial cable?

Thank you for your help and best regards
Oscar

Hi,

I have modified code little bit to send and receive messages from the shield on MQTT, connecting to MQTT server and publish the data from the shield is working perfectly but when it comes to receiving the data from the network then the shield does not give the data to the raspberry pi via URC.

I can trace inside network i can see the MQTT publish message send from MQTT server to the modem but nothing comes on the URC.

When i connect the shield directly via Qnavigator and use AT commands to subscribe then i can see the data is displayed on the Qnavigator as shown below.

I just want to know whether the configuration are correct via the python code to receive the data on URC?

Hi,

@saeedjohar I am using this shield with RPI3 and not able to configure vodafone ireland normal sim for cellular internet using the ppp installer.

Also, the results from the samples here are also inconsistent.

Am i missing something ?

thanks,
Abhijeet

Hi there,

I am running an IOT device using this PI hat, https://sixfab.com/product/raspberry-pi-lte-m-nb-iot-egprs-cellular-hat/

I have installed and everything works fine, but a stage issue, whenever the connection drops (Due to bad network usually) It does not reconnect to my LTE network. A quick restart fixes the issue, but I want the device to be running a script with LTE always ON and if it loses connection should try to reconnect, but the interface just drops unless I restart the PI.

I used the following instructions to install :
https://sixfab.com/ppp-installer-for-sixfab-shield-hat/

Any idea why this could be happening?
