I was using v46 before and BT was working fine with my carkit. Sorry, but I am no developer and canīt give you detailed information besides what can be found in the thread/wiki I mentioned...maybe those developers (e.g. mirakels) who created the updated obexd can give you more details. I have also no idea where and how to create a bug report, sorry again. I blamed neither KP nor CSSU to be the cause, just asking if it "might" be possible as I am pretty sure it broke with v47 update
