Thanks Peter.
I need to connect out.
Currently I use Widcomm, and I need to connect 7 BT devices. Using SPP, we have only one SPP , but using RFComm, we can connect up to 7 devices. So we use RFComm.
Right now, we want to Micorsoft BT Stack, My question is that In Microsoft BT stack, (1) how many serial port we can use at the same time. (2) If only one serial port, is it possible we can still use RFcomm to create virtual com to connect more one device at the same time?
Thanks again.
