Hello, unfortunately there is no support for Quectel BG95 in ofono. But nevertheless i tried to adapt the existing Quectel implementation for BG95. So i added: udevng.c ------- 8< ------------- { "quectelqmi", "qmi_wwan", "2c7c", "0700" }, { "quectelqmi", "qcserial", "2c7c", "0700" }, { "quectel", "option", "2c7c", "0700" }, ------- >8 ------------- It helps to recognize the modem, but it seems to be BUG in "setup_quectel" fucntion in "udevng.c" file. Since checking for "modem->serial" in the function produces a segfault. so i just commented it out. But after that the next problems popped up in "quectel.c"-Modul. ------- 8< ---------------------------------------- ofonod[273]: Aux: > AT+CGMM\r ofonod[273]: Aux: < \r\nBG95-M3\r\n\r\nOK\r\n ofonod[273]: plugins/quectel.c:cgmm_cb() 0x165dd0 ok 1 ofonod[273]: Failed to query modem model ------- >8 ----------------------------------------- As you can see it failed to query the model modem, even though the modem is answering correct. so i digged deeper and found out, that only the number of lines save in result-argument which is a "GATResult" is actually zero! That means somewho the answer of the modem is not parsed right! Any help is welcome! Best Regards Arash
