Bluetooth (BLE) can be turned on or off at any time by pressing and holding the Bluetooth Button on the top of your thermocycler for roughly half a second. By default, Bluetooth is disabled. A blue LED will light up next to the BLE button indicating it is enabled.
Once enabled, tap “Connect via BLE” when prompted in the smartphone app. If working with multiple Franklin thermocyclers, select the appropriate unit and tap “Confirm”. The LED on the front of your thermocycler will flash white indicating it’s connected.
