iOS A16: Intermittent packet loss on high volume / load (possible hardware level bluetooth issues) #1048

Hi all, I am just putting this here for visibility, since this is not an issue with the driver. I have been hunting down and trying to find out why we were having issues with our iOS app and A16 specific iPads. (We have tested with the A17 Pro, M2, and others with no issues). I was able to just verify using he app Light Blue on iOS that the bluetooth stack seems to drop RX data received from a subscription ID, specially when the data is over 30 bytes long, it tends to truncate the data and I just get a new packet header for the next message. If you have some other suggestions or ideas to try, please feel free to share. I currently have logs from but our software and LightBlue that show the received data missing the end of message headers and then a new start of message header coming in. I can then take this same device onto another iPad as explained above and it works as expected. We now have a total of over 10 reported cases of this issue with different users and all with the A16 iPad.

Thanks for you time,
Daniel
