We are using EM7455 managed with qmicli in Ubuntu.
Recently got a SIM that supports multiple APNs , each with different service.
We use following sequence to change APN:
qmicli -d /dev/cdc-wdm0 --wds-start-network=APN1, --client-no-release-cid
qmicli -d /dev/cdc-wdm0 --wds-start-network=APN2, --client-no-release-cid
Problem is that sometimes, connection with APN2 doesn’t succeed, and in serial console we see modem still uses the previous one:
Does modem save the APN in Flash ? Why changing the APN sometimes doesn’t succeed?
We have SINGLEAPNSWITCH custom setting to 1.
