Dear Modem Mamanger dev team,



                We are using Quectel EC25 Dual LTE on a BPI-R64 board.

                When we try mmcli command to disable a modem

                                1.            When we disable a Modem-A, it will throw Time out error and drop that Modem-A

                                2.            When we disable Modem-A,  if it get any error, Modem-B is getting dropped.

                                3.            When we disable Modem-A,  if it get any error,  Both Modems are getting dropped.,  we see following behavior.



                Currently we are using Modem Manager version 1.10 with ubuntu 18.04.



                I would like to know , whether do we have support for multiple LTE in the Modem Manager.

                When other process is executing qmicli command, if we issue mmcli commands on the same Modem,  is it handled..



Thanks

Venugopal
