Overview
|
|
********
|
|
|
|
The generic GSM modem driver allows the user to connect Zephyr to a GSM modem
|
|
which provides a data connection to cellular operator's network.
|
|
The Zephyr uses :ref:`PPP (Point-to-Point Protocol) <ppp>` to connect
|
|
to the GSM modem using UART. Note that some cellular modems have proprietary
|
|
offloading support using AT commands, but usually those modems also support
|
|
3GPP standards and provide PPP connection to them.
|
|
See :ref:`GSM modem sample application <gsm-modem-sample>` how to setup Zephyr
|
|
to use the GSM modem.
|
|
|
|
The GSM muxing, that is defined in
|
|
`GSM 07.10 <https://www.etsi.org/deliver/etsi_ts/127000_127099/127010/15.00.00_60/ts_127010v150000p.pdf>`__,
|
|
and which allows mixing of AT commands and PPP traffic, is also supported in
|
|
this version of Zephyr. One needs to enable :option:`CONFIG_GSM_MUX` and
|
|
:option:`CONFIG_UART_MUX` configuration options to enable muxing.
