CONFIG_UART_MCUMGR_RX_BUF_COUNT

Number of receive buffers for mcumgr fragments received over UART

Type: int

Help

Specifies the number of the mcumgr UART receive buffers.  Receive
buffers hold received mcumgr fragments prior to reassembly.  This
setting's value must satisfy the following relation:
UART_MCUMGR_RX_BUF_COUNT * UART_MCUMGR_RX_BUF_SIZE >=
MCUMGR_SMP_UART_MTU

Direct dependencies

UART_MCUMGR && CONSOLE

(Includes any dependencies from ifs and menus.)

Default

2

Kconfig definition
