Hi Mauro,

what i wanted to say is that i can transfer (over L2CAP) data from
console, but transfer of files redirected to stdin always fails. perhaps
i am doing something wrong? such as calling write(2) over L2CAP sockets
with buffers larger that 762 bytes?

I haven't checked the nc6 Bluetooth support so far, but the L2CAP is a
SOCK_SEQPACKET and it has an in and an out MTU. The default MTU is 672
and this means if you send data with a larger buffer, the write() will
fail.

you're right. in fact:

nc6 --mtu=672 -b address -p psm

works perfectly.
