Petrel2 bluetooth connection problems

[taimen]

I am having bluetooth connection problems with my Petrel2 (Divecan JJ-CCR model). I am trying to use the Android Shearwater cloud app to download dive information from the computer without success.
The Petrel pairs with my phone (OnePlus5) and I am able to download the dive list but downloading the actual dive information aborts in a few seconds with a "bluetooth packet error" message on the Petrel screen. Updating firmware does not work either. The same setup works fine with my Perdix AI.
I got a reply from shearwater with some generic instructions for bluetooth pairing, but setting up the connection is not the problem, it is the "bluetooth packet error" when transferring dive data.
Any ideas or similar experiences?

Had some problem recently to upgrade the firmware on my Petrel 1. Got all the needed help from Shearwater, you should keep with them, they are really dedicated.
