hi Praveen
I'm not aware of anyone implementing SDP for BTnut, although it shouldn't be more complicated than on any other platform. Most of our projects have been BTnode-to-BTnode over our proprietary L2CAP connection-less networking code. Then, when connecting to standard devices like a mobile phone, students would just figure the correct RFCOMM channel and connect without SDP. Finally, for apps like my SNIF Monitoring tool, a standard L2CAP connection was used on a fixed PSM as the tool on the PC was custom anyway.
If you get your implementation working, I will be happy to add it to the main trunk, if you like.
I've started a new Bluetooth Stack at http://btstack.googlecode.com for embedded devices. It's main difference to BTnut is that it runs single-threaded which makes porting easier. It is less matured than BTnut - only outgoing connections, no packet segmentation/reassembly, beta RFCOMM - but it should be more resource efficient and it is already used on the iPhone... It will need an SDP implementation, too, but that s not a high priority yet. However, It will when RFCOMM for incoming connections is ready.
Best,
Matthias
Post by praveen vasishthaHi,
I have been working on btnode stack for past couple of months. I am working
in implementing SDP layer for this stack. I have seen some
mails/communications that some guys are working on this already. If somebody
can share the current development, then i can also help in completing this
task.
Thanks
Praveen
