Realtag iBeacon Firmware instructions:

Modify the parameters， Tag needs to be repower (power off and then open)
The work of the state， blue LED light D1 to signal broadcast interval frequency flicker
During of the work， you can press the S2 key to stop / start broadcasting (automatic broadcasts by default when the power is turned on)
The connection state is not broadcast， disconnection is restarted broadcasting
The connection can be read by Battery Service

Realtag iBeacon API Description:

Service UUID: 0xFFA0
0xFFB0: Pairing code (Read / Write)
Ex: 000000 (default 000000=without connection password)
0xFFB1: Major + Minor ID (Read / Write)
Ex: 0x01020304 (0x0102=Major ID. 0X0304=Minor ID)
0xFFB2: iBeacons UUID (Read / Write)
Ex: 0xE2C56DB5-DFFB-48D2-B060-DOF5A71096E0 (not recommended to modify)
0xFFB3: Advertising Interval (Read / Write)
Ex: 0x05 (broadcast interval is integer times， the default 100ms: 0x05=500ms)
Service UUID: 0xFFA0
0xFFB4: device ID (Read / Write)
Ex: iBeacons#
The 0xFFB5: deployment model (Read / Write)
Ex: write 0x00 into the deployment model (0x01: non deployment model of the default value)
The 0xFFB6: sensor MPU6050 data (Realtag Sensor)
Ex: HEX 0xA0009C02983E40F7FDFFBC00FFFF
