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.

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¶

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:

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!
[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

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
