Can reliably hang GPY on expansion board with the following
I have a GPY on expansion board 2.
Have been trying unsuccessfully since last week to get LTE running ;-) Have tried everything outlined in various form posts and have contributed to that discussion ;-(
Just upgraded to latest firmware and have found a repeatable hang on the system necessitating a hard reset.
(sysname='GPy', nodename='GPy', release='1.17.2.b1', version='v1.8.6-849-1bf377b on 2018-03-16', machine='GPy with ESP32')
Essentially the problem repeatable by performing the following steps.
from network import LTE lte = LTE() lte.send_at_cmd('AT+COPS=?') # ineteract with the modem via send_at_cmd import time
At this point the system will hang until a reset.
Crtl-C won't interrupt nor any other sequences sent through the console.
@seb Problem ceased with the latest firmware.
My GPY hangs when i call lte = LTE(). I'm stuck with this for weeks already, even on 1.17.3.b1.
@seb Yes. I am only interested in CAT-M1 and have confirmed with Telstra they are for CAT-M1 (see discussions re: telstra).
Irrespective I don't believe the system should hand when importing
Any send_at_cmd performed before importing
timewill hang the current firmware.
Have you tried it ?

Are you trying to connect to regular LTE? Our modules only support LTE CAT-M1 and NB-IoT, these a lower power protocols that differ from regular LTE.
