LTE connection failure in ULPM power cycles

foresttsao · March 10, 2021, 7:56am

We encountered Octave MangOH Yellow LTE connection may fail(rmnet_data0 cannot derive IP address) in ULPM power cycles(overnight 36 rounds, sleep 496 seconds in ULPM and wake up to boot up).
FW version : 3.1.0-mangOH-0

what is AT!GSTATUS? at the time?
is it ok to use “cm data connect” at that timing?

foresttsao · March 10, 2021, 8:15am

We tried “cm data connect” but failed.
We tried “app restart modemService” and then “cm data connect”.
The connection recovered but we cannot see the device power on on the Octave detail page.

probably need to restart the application to connect to the Octave page.

foresttsao · March 11, 2021, 12:49am

Which application we can restart to connect to Octave pate?

jyijyi · March 11, 2021, 12:57am

I don’t have a mangoh yellow board, but I guess you can try the application here:

github.com

mangOH/mangOH/blob/master/sinc/octave_minimal.sinc

apps:
{
    $OCTAVE_ROOT/actions.${LEGATO_TARGET}.app
    $OCTAVE_ROOT/cloudInterface.${LEGATO_TARGET}.app
    $OCTAVE_ROOT/router.${LEGATO_TARGET}.app
    $OCTAVE_ROOT/diagnostic.${LEGATO_TARGET}.app
    $OCTAVE_ROOT/virtual.${LEGATO_TARGET}.app
}
