  This topic is very important for me as well. I would like to be always sure the device has means to reach the internet. It would be best to have priorities such that packages are preferably sent via WiFi (if present) rather than LTE. Do you think that invoking pybytes.connect() when both the configurations for LTE and WiFi are present is going to help? Another question, why can I init LTE via code without specifying the band and, on the other hand, I have to specify the band when I add the LTE config to pybytes?

  Yea I think that is the best we have available at the moment. Now if you are using a Pysense or Pytrack, you could use the pytrack.go_to_sleep() method to deepsleep or reset (power cycle) the module, but you will need to call that from the micropython of course.. There are some ways to enable watchdog timers internally but I have no expertise on that, nor do I know if the internal watchdog will detect a coredump..

  @rcolistete I seem to have got it working. I reloaded the firmware and wiped the file system while doing it. I'm still not entirely sure why the core dumps were happening in the first place (all I know is some exception was thrown), but hopefully it'll be fine for now. Thank you.

  The solution to this issue is to 'update' the modem firmware (reflash the LR6.0.0.0-41019). This will reset the baudrate of the UART communication. It is also possible to use several AT commands from the AT command manual to restore factory baudrate settings, but Im not exactly sure which ones. Best, Gijs

  You could try def http_get(url): print("get(", url, ")") _, _, host, path = url.split('/', 3) print("host", host) print("path", path) addr = socket.getaddrinfo(host, 80)[0][-1] print("addr", addr) s = socket.socket() print("connect") s.connect(addr) print("send") s.send(bytes('GET /%s HTTP/1.0\r\nHost: %s\r\n\r\n' % (path, host), 'utf8')) Note that the LTE module doesn't always play nice, to the extent that some have bypassed it for cellular comms https://forum.pycom.io/topic/6202/method-to-take-control-of-cell-modem/22

  @kjm Thank you for the response. You are right about the deint. I made a test program that would go through the steps to connect over lte, then get the address of a server to verify connection, and then call my reconnect logic. I could duplicate the same error so I added the init function call just before the attach and now it works.

  You can run globals without doing an import. For example if not 'lte' in globals(): lte=LTE() works on my gpy.

  One minor addition I wanted to make.. If AllThingsTalk uses the MQTT protocol, you should not use the HTTP request I was suggesting, but switch to the MQTTClient library from micropython

  @jcaron Ha! Glad I asked for more advice. Thank you! I’ll add one more perplexing thing about the Waveshare experiment. https://www.waveshare.com/SX1262-915M-LoRa-HAT.htm That’s what we’ve tested with in P2P mode. I didn’t test it myself but apparently they have a mesh method as well. Getting closer to the WAN part. Here’s the kicker though, they’re running on the Semtech SX1262 which is most definitely a Lora chip.

  Wanted to provide a quick update to this. I just received an NBIoT specific SIM from Twilio. Was excited to test it now that I have the NBIoT specific firmware & correct SIM enabled, but I'm getting this strange behavior. The SIM is active and confirmed by Twilio, but for some reason I am quickly disconnected. Has anyone seen this behavior before? Does anyone know some definitions around the FSM readout? It's strange because this readout seems identical to the first successful attempt with a non-NBIoT SIM. It feels like Twilio is rejecting the connection as I have signal and the connect attempt appears successful, but was hoping someone might be able to confirm.

  This last FSM report seems to have connected perfectly fine? The last message: [(2, 1, 0, '', ('18.195.176.111', 80))] Is the output of the socket.getaddrinfo() meaning the modem is able to do DNS lookup! Best, Gijs

  @AlganEren Note that some providers do not send DNS server info during the connection process (so you have to configure them manually), and that older versions of the firmware had issues with DNS over NB-IoT, apparently. You may want to check this thread: https://forum.pycom.io/topic/4247/dns-now-working-a-list-documentation-of-all-lte-nb1-nb-iot-lte-m-lte-catm1-operators-around-the-world

  Hello, you were right, my SIM subscription does not allow sending SMS... So I tried with another SIM card (orange SIM card) and I managed at last to send SMS! Great! Thank you for your help every one.
