HM-10 is a Bluetooth Low Energy (BLE) module, interfaced via serial port (UART).

HM-10 is a Bluetooth Low Energy (BLE) module.

Features:

  • conforms to BLE 4.0 specification
  • based on Texas Instruments CC2540 or CC2541 SoC
  • power: 3.3V
  • interfaced via serial port (UART)
  • uses text commands for configuration that only is sort of similar to AT commands used by modems
  • widely used by hobbyists and in embedded applications

Full specification can be found in datasheet.

Official site: Jinan Huamao Technology Company (JNHuaMao).

Be aware of the special handling needed for text command handling. Code that is written to talk to HM-10 cannot be reused to talk with normal modems/phones that uses AT commands and vice versa. Significant differences include

  • Complete lack of generic Final Result Codes (like OK and ERROR). Instead every single possible variation of result and information text needs to be explicitly handled.
  • No indication of failures will be given.
  • The syntax is very different in many, many aspects.
