= libsamsung-ipc =

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.BR
libsamsung-ipc is shared between SHR and Replicant projects. It's used in both for the Nexus S.

Source code is available under the GPLv3+ at: https://github.com/morphis/libsamsung-ipc (master branch).

ipc-modemctrl

ipc-modemctrl is the tool that comes to test libsamsung-ipc. It currently implements basic functionalities (mostly SIM unlocking and network registration).

Usage: {{{
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): {{{ ./adb shell ipc-modemctrl start --pin=1234 }}}

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!
[0] Starting modem on FMT client
[1] Starting modem_read_loop on FMT client
[2] Phone is powered up (LPM)!
[I] SIM card found
[I] SIM is initializing
[3] SIM init complete
[4] Modem is ready, requesting normal power mode
[I] SIM card found
[I] SIM is initializing
[3] SIM init complete
[5] Modem is fully ready
[I] Registered with network successfully!
[6] Registered with network! Got PLMN (Mobile Network Code): '20810'
[I] Registered with network successfully!
[6] Registered with network! Got PLMN (Mobile Network Code): '20810'
[I] Registered with network successfully!
[I] Registered with network successfully!
[6] Registered with network! Got PLMN (Mobile Network Code): '20810'
[I] SIM Phone Book init complete
}}}

If something goes wrong, please add the {{{ --debug }}} argument to get in debug mode.

Status

We were able to make the following work: * SMS (Rx/Tx) * Call (Rx/Tx) BUT NO AUDIO YET * GPRS * SIM I/O (stored contacts, etc) * SIM PIN unlocking
