Tips
1. Battery Voltage:
The voltage value is bit 0 ~ bit 6, bit 7=0 is normal voltage, and bit 7=1 is low voltage.
Battery=0xA0, binary=1010 0000, if bit 7= 1, it means low voltage.
The actual voltage is 0010 0000 = 0x20 = 32, 32*0.1v =3.2v
2. Version Packet:
When Report Type=0x00 is the version packet, such as 0143000A0B202005200000, the firmware version is 2020.05.20
3. Data Packet:
When Report Type=0x01 is data packet.
