CONFIG_BT_CTLR_TX_RETRY_DISABLE¶
Disable Tx Retry
Type: bool
Help¶
Avoid retransmission of a PDU if peer device Nack-ed a transmission in the current connection event, close the connection event so as to save current consumption on retries (in case peer has no buffers to receive new PDUs).
Enabling this will lower power consumption, but increase transmission latencies by one connection interval as the next attempt to send a PDU would happen in the next connection event instead of repeated retries in the current connection event.
Direct dependencies¶
BT_CONN && BT_CTLR && BT_HCI && BT
(Includes any dependencies from if’s and menus.)
Defaults¶
No defaults. Implicitly defaults to n.
