Hello again,
I enabled the GATT in my bluetoothd and found out that there was an
unimplemented attribute (below) and might be the reason why the iPhone
connection got disconnected after 30 secs.
2012-09-12 15:36:55.419980 > ACL data: handle 76 flags 0x02 dlen 9
ATT: Error (0x01)
Error: Attribute not found (10)
Read By Type req (0x08) on handle 0x0039
I would like to know if anyone here has a patch?.
Regards,
john
