  @andrejpekarcik UART0 is used for the REPL over USB. The regular speed is 115200. SO if you want to use that, you have to deinit REPL on UART, using uos.dupterm(None), and use Telnet for the REPL.

  Weird issue when pinging an external server

  @elizar said in Weird issue when pinging an external server: @shedaim Ping'ing takes time. Maybe the successful reply to the second ping is in fact the answer to the first ping? Using the newly added "delay" option should have fixed that, so I don't believe that's what's happening. This is what I managed to find out untill now: Trying a single ping message: Ping request UE --> Server Success Ping reply Server --> EPG Success Ping reply EPG --> MME Success Ping reply MME --> eNodeB Success Ping reply eNodeB --> UE Unknown (Doesn't show in Atom, but MME states that message has been sent) Trying two pings in rapid succession: Ping request UE --> Server Success Ping reply Server --> EPG Success Ping reply EPG --> MME Success Ping reply MME --> eNodeB Success ping reply eNodeB --> UE Unknown (Doesn't show in Atom, but MME states that message has been sent) Ping request UE --> Server Success ping reply Server --> UE Success (Arrives after 150 - 500 ms) Pinging from server to UE is successful continuously. eDRX is in state "NOT_CONFIGURED" - same as network. Tried to disable sleep of the modem using AT!="EE::disable" Additional information for the Pros: First Ping message is sent over S1AP/NAS-EPS in the initial message to the MME, which contains a Control Plane Service Request. Second ping message is sent over the same interface as an UplinkNasTransport message. Wireshark of MME messages - Download

  @kjm yes, it should work with it. Which part are you having issues with? Can you connect to the board? Which operating system are you using?

  To anyone using the Bell Canada LTE Cat M1 network: just got word from them and it seems that at this point there is PSM support but: "eDRX feature is under consideration for future availability but there is no announced plan yet". I'll be playing with the +CPSMS AT command to see what's possible.

  @eric-waai Yes, I know this promise. I already registered, but it' s not there yet. Sequans may not have provided the firmware yet, and Pycom did not start with the device replacement yet.

  @panda With the command: lte.send_at_command('AT!="setDbgPerm full"') There is also : lte.send_at_command('AT!="Help"') which gives you the command list, and lte.send_at_command('AT!="help <command>"') e.g. lte.send_at_command('AT!="help help"') telling you, how to use help to get the list section by section. The list is quite long.

  @shedaim There is a problem in the lte.attach() API concerning parsing the response from the network. @xykon adresses this in a trial firmware build at [LINK NO LONGER AVAILABLE] Please download and install that (install from file). It may fix you problem. See also this thread around https://forum.pycom.io/topic/3549/important-update-regarding-lte-modem-updates/83

  @panda I added an lte.reset() call at the start and now the program crashes on a blank line the second time it is run. Again it works fine the first time the program is run.

  @averri Besides that, I tried adafruit-ampy, which seems to be used by pycharm, and it works fine. Please be aware, that the files on the device mist be stored under /flash directory (or /sd, it mounted there). So a boot.py must have the target name /flash/boot.py

  Hey @jcaron, thanks for your response. A picture is about 10-20KB in size but the Arduino can provide the data in small chunks, say 256 bytes or 64 bytes (whatever data packet size the GPy is comfortable with). As for support by the carrier, is there a good way to find out if the city I live in (Vancouver, Canada) supports LTE CAT-M1 and NB-IoT?
