  @dnear1 Of course, a watched pot never boils... and seemingly, setting pybytes to a higher debug level seems to make firmware updates succeed.. Packet sent. (Length: 49) Packet sent.

  @Arnold-Quinsey I don't know exactly your problem, but maybe just usign 'pycom.pybytes_on_boot(False)' could answer your question?

  You can right-click on the device name to create file or folder. Next to that, you can use os.mkdir(...) to create a folder as well from the terminal, and/or open('lib/file.py', 'wb') to create a file At the moment, is not possible to automatically create the pytrack/pysense libraries in pymakr online.

  Possible to have Lopy4 connected to both Pybytes and TTN

  I do not think this is possible, as the Pybytes TTN integration couples the Lopy4 through another TTN application, using only the LoRa connection. When you use WLAN to connect through pybytes to manage firmware updates etc, and LoRa to connect to TTN, there should be no issue.

  They indeed do the exact same thing. Im not sure why we have both, but I think both of them are used throughout the pybytes library.. Gijs

  Right, that means the pybytes library is not loaded on boot (do you perhaps have pycom.pybytes_on_boot() set to False? ) You can load the Pybytes library yourself by using: from _pybytes import Pybytes from _pybytes_config import PybytesConfig conf = PybytesConfig().read_config() pybytes = Pybytes(conf) pybytes.start() Gijs

  I was hoping the same... Would have been nice if Pybytes queued these messages for the next time a device is online.

  pybytes.send_custom_message(...) will work as well (its a subsidiary of send_signal(...) )

  Here's where I'm at as of now and it's the same issue I found here: https://forum.pycom.io/topic/6310/fipy-lte-not-initialized?_=1605173686464 from @kjm @ssummers In answer to your question, it's not the reset causing the 'not initialised' error it's the denit itself, you have disposed of the lte so you need to make a new one, lte=LTE() Re network disconnections, I've never had any luck with getting the sequans to reconnect on an existing attachment. My experience in marginal RF environments is that the modem actually looses attachment but doesn't know it, lte.isattached() and lte.isconnected() are both true but trying lte.disconnect() throws an OSError. I call this ZombiModem mode & the the only fix is to reset the modem & setup a new lte/attachment/connection For now I'll just use longer intervals and fully disconnect / reconnect I guess.

  It might be related to this: https://forum.pycom.io/topic/6514/vodafone-sim-in-spain-not-working-solved-wrong-dns-sever ? I cannot be certain why it is now fixed, so if you run into the issue again let me know! Gijs

  I'm seeing this error also with a LoPy using MQTT library to retrieve data to display on a LED matrix. Firmware: 1.20.2.r1 Pybytes: 1.6.0 Initialized watchdog for WiFi and LTE connection with timeout 1260000 ms WiFi connection established MQTT ERROR! function got multiple values for argument 'user' ERROR! Could not connect to Pybytes! Pybytes configuration read from /flash/pybytes_config.json Connecting to WiFi Initialized watchdog for WiFi and LTE connection with timeout 1260000 ms WiFi connection established MQTT ERROR! function got multiple values for argument 'user' ERROR! Could not connect to Pybytes! Clearly this issue hasn't yet been fixed or even responded to. Thanks Andrew

  @alipsilc That seemed to work in getting all the nodes on the same downgraded firmware. Working through other issues and which example to use for each node before making them do something more interesting. Thanks Andrew

  The EAGAIN error is related to re-using the LoRa socket. If you redefine the socket using s = socket.socket(socket.AF_LORA, socket.SOCK_RAW) before re-using it, the issue should go away I believe.

  @Gijs I have not tried to update the firmware, but it seems like my problem has been fixed. I have successfully established LTE connection and publish the data to a server over MQTT. For the very first time that the chip trying to connect to the internet, it takes a long time (5 min) from scanning to connected. I guess a better antenna can make this process faster. Now I have to face a new problem - unstable MQTT connection. My code publishes data every two seconds. 402 runs are the most runs that I can get. Most of the time my code was errored out by the error "OSError: [Errno 104] ECONNRESET" after 20 to 100 runs. It is also turned out that publishing a long string (e.g. "3.13, 5.75, 8.56, 98987.65464, 465.56412") usually could get more runs than publishing a short string (e.g. "3.13"), which confused me a lot. Run 399: publish data over the LTE... Run 400: publish data over the LTE... Run 401: publish data over the LTE... Run 402: publish data over the LTE... Traceback (most recent call last): File "main.py", line 81, in <module> File "/flash/lib/mqtt.py", line 120, in publish OSError: [Errno 104] ECONNRESET Pycom MicroPython 1.20.2.r1 [v1.11-a5aa0b8] on 2020-09-09; GPy with ESP32 Type "help()" for more information. >>> Line 81 of my code. client.publish(topic = MQTTtopic , msg = "3.13, 5.75, 8.56, 98987.65464, 465.56412") Line 120 of MQTT library. self.sock.write(pkt, i + 1) I think I have faced the exactly the same problem when I played with my Wipy board (WiFi connection) and try to publish data through MQTT. How could I get a more rugged and stable data-publishing process?

  Hi @paul_tanner No Pybytes will not transmit location unless you request that under Pybytes. basically, we use this to identify some actions on Pybytes section for example sending a location command. the pin is used to know which pin is used under this command (also can be used as an identifier a random number) The part that holds the message details is the payload.
