Hi Nurwalid
The USRP B210 Works with Yate without any issues,
You need to ensure you have the Uhd Software and drivers to your linux box.
When you have done that issue the command uhd_find_devices it should at that point show your usrp type and serial number
You can also issue uhd_usrp_probe it will dump firmware on the USRP and check it, and give you a responce.
then in change your ybts.conf in /usr/local/etc/yate change the line in transceciver path=./transceiver-uhd
Then launch yate if you have done everything right you will get a red light on the rx/tx port and a green light on the rx port.
Hope this helps
