Generic GSM Modem

#################



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 :zephyr:code-sample:`GSM modem sample application <gsm-modem>` 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 :kconfig:option:`CONFIG_GSM_MUX` and

:kconfig:option:`CONFIG_UART_MUX` configuration options to enable muxing.

config MODEM_GSM_RX_STACK_SIZE

	int "Size of the stack allocated for receiving data from modem"

	default 512

	help

	  Sets the stack size which will be used by the GSM RX thread.



config MODEM_GSM_WORKQ_STACK_SIZE

	int "Size of the stack allocated for the dedicated gsm workqueue"

	default 768

	help

	  Sets the stack size which will be used by the dedicated GSM workqueue

	  thread.



config MODEM_GSM_INIT_PRIORITY

	int "Init priority for the GSM modem driver"

	default 60

	range 0 99

	help

	  The GSM modem is initialized in POST_KERNEL using priority in

	  the range 0-99.



config MODEM_GSM_APN

	string "Access Point Name"

	default "internet"

	help

	  Specify Access Point Name, i.e. the name to identify Internet IP

	  GPRS cellular data context.



config GSM_PPP_AUTOSTART

	bool "Auto-start PPP at boot"

	default y

	help

	  This setting lets driver connect to network and initialize PPP at

	  boot. Unselect this if you want to run application code before

	  modem connects to network. See contents of "drivers/gsm_ppp.h"

	  to get an idea of the API.



config MODEM_GSM_ATTACH_TIMEOUT

	int "Timeout for attaching to packet service"

	default 30

	help

	  Before activating PPP, attachment to packet service is checked

	  using AT+CGATT. This setting dictates how much time in seconds

	  we give the modem before giving up.



config MODEM_GSM_REGISTER_TIMEOUT

	string "MCC/MNO for establishing network connection"

	help

	  This setting is used in the AT+COPS command to set the MCC/MNO

	  for the network connection context.  This value is specific to

	  the network provider and may need to be changed if auto is not

	   modem with +CESQ. Otherwise only RSSI value is read with +CSQ

	   from the modem.



config MODEM_GSM_FACTORY_RESET_AT_BOOT

	bool "Factory reset modem at boot"

	help

	  If this is enabled, the modem will be reset to factory default

	  settings first thing in the initialization sequence. This is

	  helpful if your modem has a tendency to get stuck due to cached

	  state.
