특징
-
The main functions of the module are as follows:
1. Master and slave
2. Transmission function
3. Transmission through + remote control function
4. Super large transmission unit (MTU)/Package
5. Abundant AT command control system
6. Support modification service UUID
7. Support the modification of communication mode
8. Support iBeacon
9. Support hibernation and standby
10. Ultra-long distance communication, up to 40-100 meters in ideal environment
11. Faster transmission speed, 2~8KB/S
12. Most AT instruction systems are compatible with hm-10 / hm-11
13. Support universal learning function, which can connect and learn BLE modules of other brands in the market (without password).HM-10/11 is different from HM-16/17
