SPP Example - Device Pairing fails 99% because SDP doesnt seem to broadcast the SPP service all the time #427

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
I'm using embedded BTStack on a STM32F4XX Discovery Board.

When I discover the device with my PC, I can get to the point of viewing the 
available services.
Most of the time there is NO ENTRY in there, and therefore i cant establish a 
connection to the virtual SPP com port.

Sometimes it works and i can install the com port, but not work with it.
So far I could not see a pattern in the way it works sometimes and sometimes 
not.

I use a BT USB Dongle as my Bluetooth device on that embedded system, but i 
assume it must be an issue of the btstack. 

Thanks for your help!

Hi.  I didn't see an error in SDP for quite some time and I just ported BTstack 
to a new platform, so I assume it's specific to your port. 

You can
a) run BTstack on a OS X / Linux system with another USB Dongle for testing, or,
b) send a stdout packetlog as described here:
