.. option:: 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.
