i’m facing a problem with RIL integration for U-Blox Modem on Android 7 Nougat. After RIL integration (…get it from U-Blox…) procedure, i’m able to send/receive SMS or execute a call, but it is not possible to connect to the data service.
Parsing the logcat log, i noticed some errors, during ppp handshake. Below the portion of the logcat mentioned:
In particular, I was focusing on the following mistakes:
04-07 15:19:42.998 I/QcrilMsgTunnelSocket( 1272): Couldn’t find ‘qmux_radio/rild_oem0’ socket;
retrying after timeout
04-07 15:19:42.723 D/pppd ( 2019): Protocol-Reject for ‘Compression Control Protocol’ (0x80fd) received
Anyone have an idea ?!?!
