124 +Consider the BLE coverage , there is two cases:
125 +
126 +=== **Connection Mode: Probe is near by the Charge, within BLE range** ===
127 +
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.
