120 +1. The Charger which is also a LoRaWAN End node: used to connect the probe via BLE and get the temperature and send via LoRaWAN to IoT server.

124 +Consider the BLE coverage , there is two cases:
125 +
126 +=== **Connection Mode: Probe is near by the Charge, within BLE range** ===

128 +Probe will establish connection to the charge via BLE.  and the data flow is as below.

136 +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.
