The droids we are looking for

Subject appearance

This document describes GATT characteristics used to control Triones smart RGBW BLE bulbs (like on the picture above). Yes, they look the same as [Zengge bulbs](../ZJ-MBL-RGBW (v3)/protocol.md). My guess is that all cheap Chinese bulbs looks identically to each other, and only differ in GATT characteristics UUIDs.

All the text below is a result of my own experience of reverse-engineering its protocol. Use it at your own risk, I am not responsible for your hardware.

Communication principles

TODO

The protocol

Status

Status request is used to query some generic bulb parameters, like power status, current color or built-in mode. Status query is done in "write and listen" manner, so it will not work in non-interactive gatttool mode (you won't be able to see the result). Check the code for more details.

Request

Type Write and listen
Write to FFD9
Notification from FFD4
Payload Constant, [0xEF, 0x01, 0x77]
Notification See the description below

Notification description

Resulting notification must be 12 bytes long.

  1. result[0] must be equal to magic constant 0x66
  2. result[1]: ???
  3. result[2]: power status:
    • 0x23 is for "ON".
    • 0x24 is for "OFF".
  4. result[3]: mode:
  5. result[4]: ???
  6. result[5]: speed
  7. result[6]: red color component
  8. result[7]: green color component
  9. result[8]: blue color component
  10. result[9]: white color intensity (when the bulb is in white color mode)
  11. result[10]: ???
  12. result[11] must be equal to magic constant 0x99

Speed

Some operational modes take a speed parameter that controls how fast the colors are changed. 0x01 is the fastest, 0xFF is the slowest.
