Try "sdptool browse local" from your gumstix prompt and see if your rfcomm service is running. You should see something like this -

Browsing FF:FF:FF:00:00:00 ...
Service Name: Serial Port
Service Description: COM Port
Service RecHandle: 0x10000
Service Class ID List:
  "Serial Port" (0x1101)
Protocol Descriptor List:
  "L2CAP" (0x0100)
  "RFCOMM" (0x0003)
    Channel: 1
Language Base Attr List:
  code_ISO639: 0x656e
  encoding:    0x6a
  base_offset: 0x100
Profile Descriptor List:
  "Serial Port" (0x1101)
    Version: 0x0100

If that checks out, make sure you're providing the correct pin when you "add" your Gumstix on the Windows side (I'm assuming its a Windows PC).

Subject: Re: [Gumstix-users] Bluetooth services problem- help please

i am not very experienced in linux either but i have working one gumstix with linux over last few weeks, so i can try out. but i warn u i am not an expert unlike many others who r there in the forum

as i understand the serial port error- did u specify the correct serial port. did u modify the file with the port information.

and seeing the log that since u get the gumstix login - wat happens after this, can u type in anything or is it not possible

I cannot make a serial port connection from my pc to my verdex board.

On my PC I can see the gumstix, and its name, but when I double click on
the icon to open a connection to "Serial port on Gumstix", I get a
dialog box on the PC - "The serial port connection failed: Service not

Anyone give me some clues as to what to look for on the gumstix via the
console to see what might be wrong? There are a couple of errors printed
out below during bootup, but not sure if they have anything to do with
this type of service with BT. Sorry, I am not that experienced with
Linux services



On bootup, I get the following:
