I do have Cradlepoint R1900 with EM9190 modem - Cradlepoint cannot detect the modem.
When modem is connected to router I can see message “EEPROM_Dock DEBUG Module id :” -in my opinion module is not responding correctly - it looks like it may be FW issue on the EM9190.
Can I use other device (I’m thinking about m2 → usbC board) to force the modem EM card to accept firmware, is there any procedure for this?
