Please can you help with this problem of how to select the preferred bearer type?
We have the document “AirPrime MC/SL-Series (UMTS/LTE) Extended AT Command Reference”, which says that the AT command AT!SELACQ sets the bearer preference for the MC7710 (Table 1.1).
When I tested with this command, no password was needed, but the command also didn’t work until the device was powered off and on again. I did this by rebooting the computer, or by using the command AT!RESET.
Is AT!SELACQ supposed to work like this?
I would like to test with AT!SELRAT, but previous tests have shown that this AT command is sometimes unreliable. Also, it is not documented for the MC7710.
How can I show a complete list of supported AT commands for the MC7710?
Should I use AT!SELACQ (documented) or AT!SELRAT (not documented)?
