menuconfig MODEM
bool "Modem Drivers"
help
Enable config options for modem drivers.
if MODEM
module = MODEM
module-str = modem
source "subsys/logging/Kconfig.template.log_config"
config MODEM_RECEIVER
bool "Enable modem receiver helper driver"
depends on SERIAL_SUPPORT_INTERRUPT
select UART_INTERRUPT_DRIVEN
select RING_BUFFER
help
This driver allows modem drivers to communicate over UART with custom
defined protocols. Driver doesn't inspect received data and all
aspects of received protocol data are handled by application via
work method provided. This driver differs from the pipe UART driver
in that callbacks are executed in a different work queue and data is
passed around in k_pipe structures.
config MODEM_RECEIVER_MAX_CONTEXTS
int "Maximum number of modem receiver contexts"
depends on MODEM_RECEIVER
range 1 10
default 1
help
Maximum number of modem receiver contexts to handle. For most
purposes this should stay at 1.
config MODEM_CONTEXT
bool "Modem context helper driver [EXPERIMENTAL]"
help
This driver allows modem drivers to communicate with an interface
using custom defined protocols. Driver doesn't inspect received data
and all aspects of received protocol data are handled by application
work method provided. This driver combines abstractions for:
modem interface, command handler, pin config and socket handling each
of which will need to be configured.
if MODEM_CONTEXT
config MODEM_CONTEXT_MAX_NUM
int "Maximum number of modem contexts"
default 1
help
Maximum number of modem contexts to handle. For most
purposes this should stay at 1.
config MODEM_CONTEXT_VERBOSE_DEBUG
bool "Verbose debug output in the modem context"
help
Enabling this setting will turn on VERY heavy debugging from the
modem context helper. Do NOT leave on for production.
config MODEM_IFACE_UART
bool "UART-based modem interface"
depends on SERIAL_SUPPORT_INTERRUPT
select UART_INTERRUPT_DRIVEN
select RING_BUFFER
help
To configure this layer for use, create a modem_iface_uart_data
object and pass it's reference to modem_iface_uart_init()
along with the modem_iface reference from your modem_context object
and the UART device name.
config MODEM_CMD_HANDLER
bool "Generic modem command handler"
select NET_BUF
help
This generic command handler uses a modem interface to process
incoming data and hand it back to the modem driver via callbacks
defined for:
- modem responses
- unsolicited messages
- specified handlers for current operation
To configure this layer for use, create a modem_cmd_handler_data
object and pass it's reference to modem_cmd_handler_init() along with
the modem_cmd_handler reference from your modem_context object.
config MODEM_CMD_HANDLER_MAX_PARAM_COUNT
int "Maximum number of params parsed per command"
depends on MODEM_CMD_HANDLER
default 6
help
This option sets the maximum number of parameters which may be
parsed by the command handler. This is also limited by the length
of the match_buf (match_buf_len) field as it needs to be large
enough to hold a single line of data (ending with /r).
config MODEM_SOCKET
bool "Generic modem socket support layer"
help
This layer provides much of the groundwork for keeping track of
modem "sockets" throughout their lifecycle (from the initial offload
API calls through the command handler call back layers).
To configure this layer for use, create a modem_socket_config
object with your socket data and pass it's reference to
modem_socket_init().
config MODEM_SOCKET_PACKET_COUNT
int "Maximum number of stored packet sizes per socket"
depends on MODEM_SOCKET
default 6
help
As the modem indicates more data is available to be received,
these values are organized into "packets". This setting limits
the maximum number of packet sizes the socket can keep track of.
endif # MODEM_CONTEXT
config MODEM_SHELL
bool "Enable modem shell utilities"
select SHELL
help
Activate shell module that provides modem utilities like
sending a command to the modem UART.
