Encrypted data in Gazell acknowledgement packet

[bato]

Hi,

I am working with nRF52833 using the SDK17 Dynamic Pairing example. I was able to expand on it for my use case, and the application is now correctly receiving data from the device to host. Can you provide an example of how to send back encrypted data inside an acknowledgement from the host to the device? I can't seem to find a solution for this, but it seems like a common use case.

Thanks!

Hi,

 

Unfortunately, this is not possible with GZP, when encrypting data.

The ACK payload is reserved for the key update:

Kind regards,
