rfcomm settings
 

hi,
i'm writing a simple cmd-line application based on serial bt communication to a bt reader.
Yes, this app is very similar to a gps-based application, but...

what i did:

* hcitool scan
and find reader's bt address , OK
* rfcomm connect 0 [BT ADDRESS] 1 &
and connect to bt reader creating /dev/rfcomm0 , OK

I have to use a perl script to open the serial port, but there's something wrong...

I think it's a serial port setting problem: how can i set flow control, speed etc.?

BtPlugin and other tool do automatically, but i have to do it using command line or using perl.

My perl script (php too) worked well on windows/linux uding mode/setserial using a pcmcia device on a serial port...

Can you help me?
Thank you in advance,
mbertazz

The advice I can give to you off the bat is to double-check your channel. Different channels connect to different services.

Other than that I had no problem talking to my cellphone using Python and RFCOMM.

Probably even easier with Python and PyBluez, too.

Such parameters make no sense with bluetooth. They can be set but they are ignored. Problem is probably somewhere else (local or remote rfcomm channel number). You can't use same local port for more connections so choose something unique on n770 side. Also try sdptool browse to check what ports/services are available on the remote device.

thank you very much: i don't care about i/o settings and i see is a permission problem, resolved with nochroot and/or chmod on /dev/rfcomm0

bye
