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
