HID Profile

[Jorued]

Hi,
in the Datasheet I've seen, that the ESP32 Bluetooth supports HID. I've found no specs or examples, where this profile is used. Could someone give me a hint how to use this module as a human interface device?

Thanks

Sorry, HID is not supported in the esp-idf yet. We will add it eventually.

Thanks for the quick answer. Do you got a timeline for this feature?

also interested !

Can anyone spare a few minutes and explain "HID" or provide a reference link that one thinks is good?

There's a lot of different levels Bluetooth HID Profile could be explained at, but wikipedia has a very high-level summary:
https://en.wikipedia.org/wiki/List_of_B ... _.28HID.29

And for an extremely low-level summary, you can download the HID Profile specification PDF here:

Any progress in the HID?

I would like my ESP32 to act as a bluetooth keyboard. As I understand, this is not currently possible. Will support for the HID profile allow this? Is there any progress on this matter?

For the ESP32 to understand HID, we need to implement BT Classic first (HID is in theory possible over GAT/BTLE, but not many devices use this.) Implementing BT Classic is on its way; I assume we'll be adding profiles to that afterwards.

You'd be surprised at how many are implementing HOGP these days.

Quite a bit of use of HOGP. What would be interesting as a use is to make a HOGP gateway engine that is controlled by way of BLE and offers a bridge to select HOGP devices to allow HID support for Classic-only devices. Pair it to one or two HOGP devices and then let Classic devices do traditional HID pairing.

In fact, this is one of my pet projects I'm waiting for Classic support to happen for.
