Jes, >>> at this point i'm not sure who is at fault here. after reading >>> the spec i was not sure if *entire* rfcomm frame must fit into >>> l2cap mtu, or segmentation is allowed. i need to re-read the spec >>> and look at more dumps from different bluetooth devices. it >>> seems to me that if l2cap channel was configured to use 132 bytes >>> mtu then device should not send larger packets, so my first >>> impression is that the phone has a bug. >>> >>> as workaround you might want to try this: >>> >>> 1) edit /sys/netgraph/bluetooth/include/ng_btsocket_rfcomm.h file >>> and change RFCOMM_DEFAULT_MTU from 127 to 667. >>> >>> 2) re-compile ng_btsocket module, i.e. >>> >>> # cd /sys/modules/netgraph/bluetooth/socket/ # make depend # make >>> # make install >>> >>> 3) reboot and try again >> >> No, it doesn't work nor obexapp in client mode with that change.
