  @kjm For people using Atom the this is a possible approach. But not all people do, and this approach makes quite a few assumptions, like that the image fits into flash. And there a lot if threads about problems with Atom and syncing. Your approach is an alternative, but people will too have issues with it.

  Finally! import time, network lte=network.LTE() def _getlte(): if not lte.isattached(): print('lte attaching '); lte.attach() while 1: if lte.isattached(): print(' OK'); break print('. ', end=''); time.sleep(1) _getlte() print('configuring for sms', end=' '); ans=lte.send_at_cmd('AT+CMGF=1').split('\r\n'); print(ans, end=' ') ans=lte.send_at_cmd('AT+CPMS="SM", "SM", "SM"').split('\r\n'); print(ans); print() print('receiving an sms', end=' '); ans=lte.send_at_cmd('AT+CMGL="all"').split('\r\n'); print(ans); print() print('sending an sms', end=' '); ans=lte.send_at_cmd('AT+SQNSMSSEND="61419123456", "This is the SMS content"').split('\r\n'); print(ans) gives configuring for sms ['', 'OK', ''] ['', '+CPMS: 6,30,6,30,6,30', '', 'OK', ''] receiving an sms ['', '+CMGL: 1,"REC READ","+61419123456",,"19/07/07,16:29:43+40"', 'C', 'Text to gpy test', 'OK', ''] sending an sms ['', '+SQNSMSSEND: ID,14', '', 'OK', ''] hope this saves someone some trial & error time.

  I think I might have a flash memory problem, something that has haunted me with GPYs from the getgo. If I upload then remove then upload boot.py & main.py several times I seem to get a more stable system. It's like the first write of new software is not enough.

  @robert-hh It still doesn't seem to work for me even after setting the DNS servers. Aside from this method is there another way I can verify my connection?

  I think you're correct, seeing a register rather than the actual modem state. What complicates this issue further is that reading the register also seems to clear it. So that print('checking LTE') c='connected' if lte.isconnected() else 'not connected'; print('modem is', c) a='attached' if lte.isattached() else 'not attached'; print('modem is', a) a='attached' if lte.isattached() else 'not attached'; print('modem is', a) produces checking LTE modem is connected modem is attached modem is not attached

  18s wakeup time from deepsleep

  @kjm The Pycom devices need between 1-2 seconds to start up. There is some analysis of that in the forum, based on the supply current analysis. LTE devices are slower than e.g. the WiPy. I do not know what's in your main.py script. But that one may take some time. LTE.attach() from power on for instance takes at my place 15 seconds and more. P.S.: Your formula above looks a little bit strange, because in the statement: sleep=600-diff you mix physical units. The unit of 600 is implicitly s (seconds), the unit of diff is ms (milliseconds).

  @jcaron No the rtc.ntp_sync fails to connect to time.google.com a lot on wifi & the default 1970 timestamp is what the rtc defaults to when it's not synced. I have to resync the rtc after each wakeup on the gpy because it doesn't keep time during deepsleep.

  @jcaron Yeah I had to re do urequests. So hard for a plod to do surgery on a library file & so distracting from the main task of writing a bullet proof main.py. Who are these geniuses that write socket programs sans timeouts or try/exception protection?

  @kjm Since main.py is executed on the target, it is accessing the files on the target. The GPY has no acces to the PC file system. The only thing that you can get is synchronizing the lib files form you Atom/PC library to GPY. I do not work with the pymakr plug-ins, so I cannot give you details, but there were threads of synchronizing a project directory with the target module.

  Which watchdog are you using? The pycom.wdt_on_boot(True); pycom.wdt_on_boot_timeout(30000) is normally setup before you run your code & it's pretty useless. It will only reboot an idle gpy, won't wake it from deepsleep, won't cover boot.py or main.py latchups, heartbeat fails or pycoms unique zombie 4s blue flash which looks like a heartbeat but isn't. The wdt=machine.WDT(timeout=30000), on the other hand, I've found to be more useful.
