I have FX30S LTE - M/NB-IoT units I am testing and am
not able to get data session through host up using AT!SCACT.
I recall in the past being able to use WP modules to connect to cellular network
in three different ways:
- using legato cm connect (internal legato connection)
- using ppp (host connection via serial port)
- using scact (host connection via USB)
I am able to successfully connect usign methods #1 and #2
above usign two different FX30S devices and two different SIMs / data plans.
I am not able to get the SCACT connection to work with either one, however.
The AT!SCACT=1,1 fails with:
at!scact=1,1
+CME ERROR: no network service
I have updated FX30 firmware to the latest FW on Sierra Source
REl 14
FX30_WP77xx_full_R14.1.1.002-att-SWI9X06Y_02.36.06.00.cwe
The APNs are correct for the SIMs / data plan(s).
The module shows registered home NW very strong signal strength
I read through all the forum posts I could find on both the legato and Sierra forum sites
I was not able to find a solution.
I tried using another PID than default PID 1 (i.e. PID 2)
with corresponding change in SCACT command but with the same result.
I have tried SELRAT = LTE only and AUTOMATIC
and have looked at AT!SELCIOT. It was set to LTE M1: 0x02
which allows it to register on the NW. I tested the others but it
doesn’t register with them. I would expect M1 to be correct.
I tried SELRAT 00 and 06. The result is always the same failure.
Please advise as to how a connection over USB using AT!SCACT can be accomplished.
Thanks
