What's your application? Could you develop your application based on the SPP demo?
I have tried the demo SPP project. It works fine.
After this, I created this eq_spp project following the attached tutorial. I could not see a big difference between them. When I run eq_spp, it seems the SPP library has been started, but its three callback functions don't work, if I connect/disconnect it, as I could not see the trace information. The connect/disconnect seems no problem, as I can see on windows, the status of bluetooth changed from paired to connected.
I found this in the snip.bt.spp demo:
#if defined (CYW20706A2)
// Initialize RFCOMM. We will not be using application buffer pool and will rely on the
// stack pools configured in the wiced_bt_cfg.c
I added this initialisation into the project I created and it works
That's great! Thanks a lot for your sharing.
