133 +Consider the BLE coverage , there is two cases:
134 +
135 +=== **Connection Mode: Probe is near by the Charge, within BLE range** ===
136 +
137 +Probe will establish connection to the charge via BLE.  and the data flow is as below.

145 +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.

147 +For example:
148 +
149 +1) User can use BH01 BLE to LoRaWAN converter to pick up the BLE signal to IoT Server
