Hi Guys,
I am testing Sierra 5G modem EM9190. my kernel version is V4.4.13 and use the default driver cdc_mbim.ko. the modem randomly can't dial success after I reboot system.
I checked AT command 'AT!GSTATUS' and confirm the modem can connect cell station successfully, but mbim-network always execute fail. the error log is "error: couldn't open the MbimDevice: Failure".
I am using libmbim version 1.14.0. do you any guys encounter the same issue?
