[arch-general] Cannot receive files via bluetooth

Hello, it seems some bluetooth has overwritten my bluetooth main.conf, as last change has been on September, 26th. Also, I cannot receive files any more, so I guess, I'd cahnaged sth. there. Unfortunately, I cannot remember, what changes I'd made in the past. :-( Could You probably tell me, what might cause the non-functioning file transfer? Sending files works, btw. Kind regards Peter
