I had a clean install of LE 9.0.1 Generic version, and found out that the rtl8723bs bluetooth not detecting anything; randomly it will freeze the whole system in the process even the logfiles stated everything loaded successfully and working. Then, I went on tinkering and testing using my Lattepanda by compiling my own LE.
I found out that activate the 2 option in linux kernel config will immediately fixed the problem.
The rtl8723bs needed to enabled the 2 option below to be able to detect bluetooth device properly:
Is there anyway LE developer enable the option above?
