standard, operating frequency range is 2.4GHZ range, modulation mode is GFSK, maximum transmission
power is 0db, maximum transmission distance is 80 meters, adopts original imported chip design, and
supports users to modify device by AT command. Names, service UUIDs, transmit power, pairing
passwords, and other instructions are convenient and quick to use. For module information, see aurora-

and receive data.
3：Support 3 modes of work (see the description of AT+STARTEN instruction function).
4：Support (serial port, IO, APP) sleep wake up.
5：Support WeChat Airsync, WeChat applet and APP communication.
6：Support 4 channel IO port control.
7：Support high precision RTC clock.
8：Support PWM function (can be controlled by UART, IIC, APP, etc.).
9：Support UART and IIC communication mode, default to UART communication.
10: iBeacon mode (support WeChat shake protocol and Apple iBeacon protocol).
11: Host transparent transmission mode (transmission of data between application modules, host and
slave communication).
3.2.7.1 Use app to communicate with the serial port
1) Install "hummer-bot\JDY-16\BLETestToos.apk", then turn on Bluetooth.
2) Open app, you will be asked to allow location permission at first, please allow.
