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.

Using Software serial on ESP8266 with Lua

I need to use ESP8266 standalone. I want to connect HM-10 bluetooth module to it and fire its AT commands and read the UUID of devices nearby. I can do that by firing AT commands on HM-10 from Arduino and FT232RL. But how do I do it in Lua?

HM10 BLE 4.0 Send AT Commands instead of passing through serial

When I send any commands to the HM10 BLE Bluetooth module, it sends the commands through bluetooth instead of the HM10 module processing the command. For example, I expected to send AT and have the module respond with "OK", but it sends the text…
