config MCUMGR_SMP_BT
bool "Bluetooth mcumgr SMP transport"
select MCUMGR
select BT
select BT_PERIPHERAL
select BT_GATT_DYNAMIC_DB
help
Enables handling of SMP commands received over Bluetooth.
config MCUMGR_SMP_BT_AUTHEN
bool "Authenticated requirement for Bluetooth mcumgr SMP transport"
depends on MCUMGR_SMP_BT
select BT_SMP
default y
help
Enables encrypted and authenticated connection requirement to
Bluetooth SMP transport.
config MCUMGR_SMP_SHELL
bool "Shell mcumgr SMP transport"
select MCUMGR
select SHELL
select SHELL_BACKEND_SERIAL
select BASE64
help
Enables handling of SMP commands received over shell. This allows
the shell to be use for both mcumgr commands and shell commands.
config MCUMGR_SMP_SHELL_MTU
int "Shell SMP MTU"
default 256
depends on MCUMGR_SMP_SHELL
help
Maximum size of SMP frames sent and received over shell. This value
must satisfy the following relation:
MCUMGR_SMP_SHELL_MTU <= MCUMGR_BUF_SIZE + 2
config MCUMGR_SMP_UART
bool "UART mcumgr SMP transport"
select MCUMGR
select UART_MCUMGR
select BASE64
help
Enables handling of SMP commands received over UART. This is a
lightweight alternative to MCUMGR_SMP_SHELL. It allows mcumgr
commands to be received over UART without requiring an additional
thread.
config MCUMGR_SMP_UART_MTU
int "UART SMP MTU"
default 256
depends on MCUMGR_SMP_UART
help
Maximum size of SMP frames sent and received over UART, in bytes.
This value must satisfy the following relation:
MCUMGR_SMP_UART_MTU <= MCUMGR_BUF_SIZE + 2
source "subsys/mgmt/Kconfig.mcumgr"
if MCUMGR
config MCUMGR_BUF_COUNT
int "Number of mcumgr buffers"
default 4
help
The number of net_bufs to allocate for mcumgr. These buffers are
used for both requests and responses.
config MCUMGR_BUF_SIZE
int "Size of each mcumgr buffer"
default 384
help
The size, in bytes, of each mcumgr buffer. This value must satisfy
the following relation:
MCUMGR_BUF_SIZE >= transport-specific-MTU + transport-overhead
config MCUMGR_BUF_USER_DATA_SIZE
int "Size of mcumgr buffer user data"
default 4
help
The size, in bytes, of user data to allocate for each mcumgr buffer.
Different mcumgr transports impose different requirements for this
setting. A value of 4 is sufficient for UART, shell, and bluetooth.
