# Bluetooth HF2
|
||||
|
||||
The Bluetooth HF2 service implements a subset of [HF2](https://github.com/Microsoft/uf2/blob/master/hf2.md), namely the serial message logging.
|
||||
|
||||
## Service
|
||||
|
||||
### HF2 service
|
||||
|
||||
* UUID: ``b112f5e6-2679-30da-a26e-0273b6043849``
|
||||
|
||||
### TX Characteristic
|
||||
|
||||
* Optional
|
||||
* UUDI: ``b112f5e6-2679-30da-a26e-0273b604384a``
|
||||
* NOTIFY only
|
||||
|
||||
This characteristic mostly emits HF2 serial messages. The first byte contains the type of message and length in the lower 6 bits. The message contains up to 19 bytes.
|
||||
|
||||
This service is supported by the MakeCode editor to receive messages.
