Hi,
I’ve updated the Quectel EG25-G modem in my PinePhone with QFirehose.
The modem in general is still working, but ever since the firmware update, voice calls fail.
The modem responds correctly to AT commands, but ATD results in an instant “NO CARRIER” and going through ModemManager results in org.freedesktop.ModemManager1.Error.MobileEquipment.Unknown.
ATI identifies the firmware as
Quectel
EG25
Revision: EG25GGBR07A08M2G
The modem-power driver identifies it in more detail as
Project Name: EG25G
Project Rev : EG25GGBR07A08M2G_01.002.07
Branch Name: 9x07_R07_NEW
Custom Name : STD
Build Date: 2020-06-13,09:14
Version: SBLR07EG25G01_1:37500: May 30 2
Version: TZR07A03: Dec 2 2019
Version: RPMR07A03_1:37500: Dec 2 2019
The various presets look fine to me:
QDAI is ‘1,1,0,1,0,0,1,1’
QCFG ‘risignaltype’ is ‘“physical”’
QCFG ‘urc/ri/ring’ is ‘“pulse”,1,1000,5000,“off”,1’
QCFG ‘urc/ri/smsincoming’ is ‘“pulse”,1,1’
QCFG ‘urc/ri/other’ is ‘“off”,1,1’
QCFG ‘urc/ri/pin’ is ‘uart_ri’
QCFG ‘urc/delay’ is ‘0’
QCFG ‘sleepind/level’ is ‘0’
QCFG ‘wakeupin/level’ is ‘0,0’ (changing to ‘0’)
QCFG ‘ApRstLevel’ is ‘0’
QCFG ‘ModemRstLevel’ is ‘0’
QCFG ‘apready’ is ‘0,0,500’
QCFG ‘airplanecontrol’ is ‘1,0’
QCFG ‘fast/poweroff’ is ‘1’
Any ideas?
