The Petrel 1 supported traditional Bluetooth only (no BLE), the Petrel 2 and I believe the original Perdixs support both traditional Bluetooth and BLE. More recent Perdixs, and all Perdix AIs only support BLE. In Subsurface and Subsurface-mobile, if the Bluetooth address is prefixed by LE: then it is trying to use BLE. If it isn't, it's trying traditional Bluetooth. Subsurface-mobile may give you a choice - i.e. the address will be listed twice in the drop-down list, one with and one without the LE prefix. The desktop version in current master (but I don't think the latest release) lets you select (in the Bluetooth download screen) whether Bluetooth mode should be "Auto" (default), "Force LE", or "Force classical". Cheers, Rick
