I bought a new Premium module for my VW, the one that includes Wifi built-in, and my Galaxy S4 doesn't seem to like it very much.
Everything works as expected with the old module, but I get constant connection drops with the new one. This happened with the stock ROM, so I tried the Cyanogenmod 11 and your rSAP and Phonebook apps.
With the stock ROM, the phone connects for a few seconds, then the connection is dropped, and it never connects again.
With rSAP and the phonebook app, the phone connects for a few seconds, then disconnects, and then connects again, and so on indefinitely.
I managed to grab the logs from the system, and also from all your apps using the HCI logger, I sent them to you via private message.
BTW, I still have the old VW bluetooth module, so I can still get logs from it as a comparison. Also, can I use wireshark as is to take a look at the .cap files, or do I need some plugin or something?
