Thingy Service Documentation

[awneil]

Where can I find the specifications / documentation of the Thingy's BLE Services and Characteristics?

ie, the stuff I would use in making a Central to connect to the Thingy.

I can see stuff about the software implementation within the Thingy, but where is the documentation of the Services at the GATT level?

I think I've found it - under "Firmware Architecture":

https://nordicsemiconductor.github.io/Nordic-Thingy52-FW/documentation/firmware_architecture.html#fw_arch_ble_services

Not really the most appropriate title.

Name	UUID	Type	Data	Description
Base UUID	EF68xxxx-9B35-4933-9B10-52FFA9740042
UI service	0300
LED characteristic	0301	Write req/Read	Max 5 bytes	RGB Value: uint8_t - Mode (retained for BLE connected and disconnected): 0 = Off 1 = Constant 2 = Breathe 3 = One Shot Constant mode (retained for BLE connected): uint8_t - R intensity (0 - 255) uint8_t - G intensity (0 - 255) uint8_t - B intensity (0 - 255) Breathe mode (retained for BLE connected): uint8_t - color: 0x01 - RED 0x02 - GREEN 0x03 - YELLOW 0x04 - BLUE 0x05 - PURPLE 0x06 - CYAN 0x07 - WHITE uint8_t - intensity (1-100) [%] uint16_t - delay [ms] (50 ms - 10 s) One shot mode (retained for BLE connected): uint8_t - color: 0x01 - RED 0x02 - GREEN 0x03 - YELLOW 0x04 - BLUE 0x05 - PURPLE 0x06 - CYAN 0x07 - WHITE uint8_t - intensity (1-100) [%] Default connected behavior: Mode: Breathe Color: CYAN Intensity: 20% Delay: 3500 ms

The description's not very clear; I think it's trying to say that the format is one of:

1. Off. (1 byte)
2. Constant, R, G, B.  (4 bytes)
3. Breathe, color, intensity, delay.   (5 bytes)
4. One Shot, color, intensity.  (3 bytes)
