CONFIG_BT_CTLR_TX_BUFFER_SIZE
¶
Tx buffer size
Type: int
Help¶
Size of the Tx buffers and the value returned in HCI LE Read Buffer Size command response. If this size if greater than effective PDU size then controller will perform fragmentation before transmitting on the the packet on air. Maximum is set to 251 due to implementation limitations (use of uint8_t for length field in PDU buffer structure).
Default¶
27
