  Thanks for replying. I just do some testing and it is true that in some random time, the device didnt go to deepsleep but rather skip that step entirely. What i did to test this is running script where it report will to server within 1 second non stop unless it go to machine.deepsleep step. Base on report, it skip deepsleep stage twice in the last few hours. Do you know or anyone know where i can find more about this problem ? I have been looking in the forum but not much

  I would try to monitor the length of the output queue. See _io_thread_func in MQTTMsgHandler.py - in there there's the transmit loop and you could add some signaling there to indicate the TX queue is empty. You'll probably need to modify the code and rename the function so you are not using the builtin frozen ones.

  @dexter12 Our application is remote pump management in Australia. Currently using raspberry PIs with usb cell modems. The PI has full python & is a nice platform but usb modem choices are limited. The built in modem on the gpy is a nice idea but the limited repertoire of micropython makes code porting a pain but worth it to have another string to the bow.

  @aen Answering my own reply. I did manage to upgrade the modem to nb-iot using the uart method. The key was to use the "diff"-file and leaving out the parameter to the updater.elf file in the method call sqnsupgrade.run(...) Mini:sqnsupgrade aen$ python3.7 Python 3.7.3 (v3.7.3:ef4ec6ed12, Mar 25 2019, 16:52:21) [Clang 6.0 (clang-600.0.57)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import sqnsupgrade >>> sqnsupgrade.run('/dev/tty.usbmodemPy56c0ae','upgdiff_33080-to-41019.dup') <<< Welcome to the SQN3330 firmware updater [1.2.5] >>> Attempting AT wakeup...

  @iannucci I'm curious if you ever got this working. The TI documentation is a hot mess. If you did, can you post up some example code, please? =)
