I am trying to use a CS4070 device with the SPP mode in a .net application.
Everything seems alright :
- HID mode is working
- when I scan the SPP mode barcode and pair my device, 2 COM ports appear in the device manager as "Standard Serial over Bluetooth link"
However, when I scan a barcode, the scanner beeps 4 times and the led beside the '+' button lights up and I don't see any activity on the COM port.
What do these beeps mean and how I can solve my problem.
Other info :
The Bluetooth device is a ASUS USB-BT400
My sysinfo is :
