Hello,

Where can i find more documentation regarding keypress notification? How can it be used. Can you use this if there is no display or keyboard on my peripheral but contains a single multi purpose button to authenticate during pairing?

Hi,

Keypress Notifications are limited to Passkey Entry modes, but should also be valid for legacy pairing. The documentation is a bit unclear at this point. The explanation for NRF_ERROR_INVALID_STATE is correct, but the sentence under "details" is wrong.

Devices that are aware of the passkey notification bit in the pairing request/response should be able to make use of it. Older devices are required to set it to 0.

I have raised this as an issue internally.

Sounds like unexpected behavior. Would you mind sharing your complete project with me? Youare using SDK 12.2.0?
