libsamsung-ipc is a free implementation of the protocol to speak with modems found in most Samsung devices. It is the low-level library used to communicate with the modem and needs an upper-layer (RIL) to interface with the system.
libsamsung-ipc is shared between SHR and Replicant projects. It's used in both for the Nexus S.
Source code is available under the GPLv2+ at: https://github.com/morphis/libsamsung-ipc (master branch).
The library is mostly complete
ipc-modemctrl is a deprecated tool that was used at the beginning of the work for talking to the nexus S modem. It implemented basic functionalities (mostly SIM unlocking and network registration).
usage: ipc-modemctrl <command> commands: start bootstrap modem and start read loop power-on power on the modem power-off power off the modem arguments: --debug enable debug messages --pin=[PIN] provide SIM card PIN
Please run ipc-modemctrl like this (from host pc):
assuming your SIM PIN is 1234. If you don't have any SIM pin, don't pass the --pin argument.
It should go like this:
[I] Got SIM PIN!  Starting modem on FMT client  Starting modem_read_loop on FMT client  Phone is powered up (LPM)! [I] SIM card found [I] SIM is initializing  SIM init complete  Modem is ready, requesting normal power mode [I] SIM card found [I] SIM is initializing  SIM init complete  Modem is fully ready [I] Registered with network successfully!  Registered with network! Got PLMN (Mobile Network Code): '20810' [I] Registered with network successfully!  Registered with network! Got PLMN (Mobile Network Code): '20810' [I] Registered with network successfully! [I] Registered with network successfully!  Registered with network! Got PLMN (Mobile Network Code): '20810' [I] SIM Phone Book init complete
ipc-modemctrl Status¶We were able to make the following work:
- SMS (Rx/Tx)
- Call (Rx/Tx) BUT NO AUDIO YET
- SIM I/O (stored contacts, etc)
- SIM PIN unlocking
