Re: [Gumstix-users] serial bluetooth console not very reliable

[Miguel P. C. <mig...@gm...>]

Hi Greg ...
It should be possible to connect, stablising a PAN network via 
bluetooth, then using ssh. There are many tutorials on the site. But, I 
was not able to do it.
However, I stablished serial console using rfcomm. I used the kermit on 
Linux.
I had the kermit configured for the tweener, so I used the same file, 
and changed the /dev/ttyS0 (my serial port on the Linux Box), for the 
/dev/rfcomm0, wich was the serial port  emulated by the bluetooth .
I didn´t change anything on the gumstix, but I did modified the 
rfcomm.conf file on the Linux Box . That file is on /etc/bluetooth.The 
modification I made , was to put the MAC o the bluetooth on the gumstix. 
(Wich I obtained by hcitool scan). That way, the Linux box stablish the 
connection automatycally when the gumstix is connected, and I all have 
to do is run kermit.I had worked for a long time, without any problems. 
However, once I tried to paste some text, and then the connection died, 
and I had to restart the gumstix manually.

I dont have the rfcomm.conf file here, but it was something like this

rfcomm 0{
    auto (wich was commented, and I un-commented )
    MAC of the gumstix  (Wich was something like 00-00-00-00-that, and I 
put my gumstix MAC)
    (other stuff)
}

I hope this might help
Greeting from Chile ...
Miguel
