Before capture was started:
- Wifi is disabled
- Airplane mode turned on
During capture:
- Airplane mode turned off
- Waited for 4G VoLTE icon to appear in Android
- MT call, not accepted (timeout)
- 2. MT call, accepted
- Hang up the call from Android
- (Bad signal strength, 4G barely works here)
Notes about AT commands:
- Standard: 3GPP TS 27.007
- MTK seems to have non-standard commands that extend the standard commands and
start with E instead of C, e.g. EFUN instead of CFUN
- The AT commands listed are generated from the strace dump, specifically from
what mtkfusionrild sends to the android debug log (because these were the
easiest to extract). Some lines have ***, e.g. EIMSXUI=***, because the
information is redacted for the android log. When searching in the original
strace dump (e.g. for EIMSXUI), the original AT command without redacted
information can be found.
