Link Supervision Timeout
Parameter # 1698
SSI # F8h 06h A2h
Link supervision timeout controls how quickly the digital scanner senses that the Bluetooth radio lost connection to
the remote device. A lower value helps prevent data loss at the edge of the operating range while a larger value
helps prevent disconnects due to the remote device not responding in time. If you are experiencing occasional
disconnects and the digital scanner is able to reconnect, increase the link supervision timeout value.
NOTE The digital scanner only controls Link Supervision Timeout in Master Mode.
