Enables handling of SMP commands received over Bluetooth.

Enables handling of SMP commands received over shell. This allows
the shell to be use for both mcumgr commands and shell commands.

prompt "Shell SMP MTU"

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
endif

prompt "UART mcumgr SMP transport"

default n
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.
if MCUMGR_SMP_UART
config MCUMGR_SMP_UART_MTU
int
prompt "UART SMP MTU"
default 256
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
endif
config MCUMGR_BUF_COUNT
int
prompt "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
prompt "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
prompt "Size of mcumgr buffer user data"
default 7
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 7 is sufficient for UART, shell, and bluetooth.
