After 10s of inactivity during the transfer I kill the obex process so the link gets closed. 1088497499.412666 < ACL data: handle 0x002a flags 0x02 dlen 12 L2CAP(s): Disconn req: dcid 0x0083 scid 0x0040 Do you see anything strange here? I guess i need a PA to debug this. Since this happens on SE Phones only i'll try to get somone to talk to there. As i sayd it heappens not always but verry often in the moment when another chip is paging. Maby this makes the phones stack crazy when they jump on the same freq? Anyways i guess this is not a bluez issue so thanks for the help so far.
