HM-10 BLE Bluetooth 4.0 CC2541 Wireless Module is a BLE module for an embedded system to get BLE wireless communication with BLE capable devices (e.g. Android, iPhone, and iPad).
It is fully configurable by a rich and well documented AT command-set and allows transparent data communication via serial UART (default baud rate 9600bps). RoboticsBD
The Bluetooth4.0 HM-10 is basically a breakout board for cc2541, it broke out the LED pins, RX/TX and also adding the voltage regulator that regulates 5v to 3.3 v. RoboticsBD
HM-10 and HM-11 series Bluetooth module use TI CC2540 chip, configure 256KB space and support the AT command. Users can change the role (master, slave mode) and the serial port baud rate, equipment name, matching password and other parameters on-demand. It is very flexible to use.
The most complete, most convenient, and most stable Bluetooth data transmission, remote control and data acquisition module. Master-slave in one, transparent transmission, replacing the serial port. Remote control, transparent transmission, MCU is unnecessary. Remote data acquisition, transparent transmission, MCU is unnecessary. Featured By RoboticsBD.
The HC Bluetooth module is an older design and may not be compatible with the latest Android or iOS devices. For reliable operation, please use it with an older Android/iOS device, or alternatively use a BLE scanner app to detect and connect to the module.
