Using bluecove on Raspberry

[gwolfsystems]

Hi, I'm starting with my raspeberry. I decide to start using bluetooth on my Pi connecting a bluetooth Dongle. I try using bluecove library. This library works good when I try to connect 2 pcs with windows, but, when I try to start my demo on de Pi, appears a error on the prompt "The connection implementation for btspp cannot be found". I build the bluecove-gpl in my PI but It stills non working. Can you Help me? Thank you!

I looked for the answer but when I try to run my program I get the error message
"javax.microedition.io.ConnectionNotFoundException: The connection implementation for btspp cannot be found." I don´t know what I have to do.

I know nothing of BlueCove, but the SPP profile is not loaded by default. It may be as simple as

Code: Select all

sdptool add SP

. Before running your code. Otherwise, I'd look into getting Bluetooth serial communications working with command line tools, before programming it with BlueCove.

I can only suggest the same. From a command line, before running your code, enter

Code: Select all

sudo sdptool add SP
