I’ve connectCore 8M mini dev board and EC25 PCIe modem. I installed both SIM and Modem properly, but the Android system doesn’t recognize it.
How can use connect core 8M mini with EC25 ? is it possible to use ?
You’d have to write your own modem driver/RIL

RIL selection
For proper handling of the modem in Android, manufacturers provide their own proprietary RIL (Radio Interface Layer) binaries for every modem family/model.
The default Digi Embedded Android images contain different RILs for each supported modem in the list above but you must configure which RIL to use before booting Android.
