Detailed Description

Local connection latency option.

   Local connection latency is a feature which enables the slave to improve
   current consumption by ignoring the slave latency set by the peer. The
   local connection latency can only be set to a multiple of the slave latency,
   and cannot be longer than half of the supervision timeout.

   Used with @ref sd_ble_opt_set to set the local connection latency. The
   @ref sd_ble_opt_get is not supported for this option, but the actual
   local connection latency (unless set to NULL) is set as a return parameter
   when setting the option.

Note

The latency set will be truncated down to the closest slave latency event multiple, or the nearest multiple before half of the supervision timeout.

The local connection latency is default off, and needs to be set for new connections and whenever the connection is updated.

Return values

NRF_SUCCESS	Set successfully.
NRF_ERROR_NOT_SUPPORTED	Get is not supported.
BLE_ERROR_INVALID_CONN_HANDLE	Invalid connection handle parameter.
