129 +=== **Connection Mode: Probe is near by the Charge, within BLE range** ===

139 +Probe will auto swtich to BLE broadcast mode and broadcast the data via BLE. Any BLE Scaner can pick up the signal and send to IoT server.

141 +For example:
142 +
143 +1) User can use BH01 BLE to LoRaWAN converter to pick up the BLE signal to IoT Server
