sixfab / pico_lte_micropython-sdk Goto Github PK

The MQTT tutorial mentions the examples/mqtt directory, but it doesn't exist in this repository.

The closest relevant example I can find is in examples/thinkspeak.

Hi,
I have registered and activated my PicoLTE asset on the SixFab.com (and provided the required payment to get a positive balance).

I was trying to get the MQTT example at work but I got a connection issue on the Network.

>>> from pico_lte.utils.status import Status
>>> from pico_lte.core import PicoLTE
>>> from pico_lte.common import debug
>>> picoLTE  = PicoLTE()

Now, the red LED turns ON, the blue LED blinks shortly every 2 seconds.

Then, I call the register_network() which doens't return.

>>> picoLTE.network.register_network()

Some additional tests

I did located the debug module but have not been able to get more information from it.

>>> picoLTE.network.get_apn()
{'status': 0, 'response': ['+CGDCONT: 1,"IPV4V6","super","0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0",0,0,0', 'OK'], 'value': 'super'}

>>> picoLTE.network.get_operator_information()
{'status': 0, 'response': ['+COPS: 0', 'OK'], 'value': '0'}

>>> picoLTE.network.base.get_all_cells()
{'response': 'timeout', 'status': 2}

I noticed that get_all_cells() takes time to respond (about 1 or 2 minutes) before returning a timeout.
It seems that the QueCTEL module cannot get registered on the mobile network.

Is there an easy way to spy the atcom messages exchange with the QueCTEL module ?

Cheers
Dominique

Json is returned truncated to the first comma. It seems to be because of using split(",") in line 547 in mqtt.py.

When scrolling through the documentation for HTTP(s) connection, it took me a while and some digging on GitHub to find out how to connect to an endpoint using basic authentication. I thought adding the username password to config.json is sufficient.

BUT, you need to run picoLTE.http.set_auth() additionally to set authentication.

picoLTE = PicoLTE()

picoLTE.network.register_network()
picoLTE.http.set_context_id()
picoLTE.network.get_pdp_ready()
picoLTE.http.set_auth()
picoLTE.http.set_server_url()

debug.info("Sending a POST request.")

Maybe this can be added to the documentation, since one will usually use authentication with an public endpoint
