CONFIG_BT_DEVICE_APPEARANCE

[Oli]

Hi,

I would like to ask what is CONFIG_BT_DEVICE_APPEARANCE and what does the value 833 represent? Where can I find the values that can be assigned to this configuration?

Thanks,

oli

Hi,

See this document from Bluetooth SIG:

https://specificationrefs.bluetooth.com/assigned-values/Appearance%20Values.pdf

833 is 0x341 in hex, so this is then:

Okay. Saw that too and I just needed to confirm. Thank you, Sigurd!

In the context of Bluetooth configuration in software development, `CONFIG_BT_DEVICE_APPEARANCE` is a configuration parameter used to specify the appearance of a Bluetooth device. The Bluetooth specification defines a list of standardized appearance values that represent different types of devices. These values are used to provide additional context about the type of device to other Bluetooth devices during the discovery process.

The value `833` represents a specific appearance value assigned to a Bluetooth device. In this case, `833` corresponds to the appearance of a "Sports Watch" according to the Bluetooth Assigned Numbers document (www.bluetooth.com/.../).

Here are some common appearance values defined by the Bluetooth specification:

- `0`: Unknown
- `64`: Generic Phone
- `128`: Generic Computer
- `192`: Generic Watch
- `193`: Sports Watch
- `256`: Generic Clock
- `384`: Generic Remote Control
- `448`: Generic Eye-Glasses
- `512`: Generic Tag

You can find the complete list of appearance values and their corresponding friday night funkin descriptions in the Bluetooth Assigned Numbers document linked above. This document is maintained by the Bluetooth Special Interest Group (SIG) and provides a comprehensive list of assigned numbers, including appearance values, for various Bluetooth profiles and services.
