Support serial port firmware upgrade function

2. System function:

The module factory default configuration: default baud rate 9600, N, 8, 1, slave mode, no sleep, transparent transmission + remote control mode.

The HM-16 pin is compatible with our HM-09,

HM-10, HM-10C, HM-12C, HM-18, old customers do not need to change the PCB, directly and easily upgrade.

The main functions are as follows

1. Master and slave

2. Transparent transmission function

3. Transparent transmission + remote control function

4. Large transmission unit (MTU) 256Bytes/Package

5. Rich AT command control system

6. Support to modify service UUID

7. Support to modify the communication method

8. Support iBeacon

9. Support sleep standby

10. Ultra-long-distance communication, up to 60 meters

11. Faster transmission speed, 2~8KB/S

12. The AT command system is compatible with HM-10/HM-11
