Hi dears,
I created a TX usrp an RX usrp object (using uhd::usrp::multiusrp::make())
using two different threads.
When I try to set subdevice for them the first thread can set subdevice
successfully but hte later fails to set it and throw an excption with this
error message: "Error: map::at".
(Example setting=> TX subdev=A:0, antenna=TX/RX; RX subdev=A:0 (or B:0),
antenna= RX2)
If I comment the methods to set subdevice for the later thread (e.g. for RX:
rx_usrp->set_rx_subdev_spec("B:0")) my code works correctly.
I wonder why this problem is for! As UHD examples such as txrx_loopback_tofile,
set subdevice for both TX and RX separately and it works fine. The only
difference between this example and mine is that I am using two different
threads.
It is worth noting that my code works correctly for N200 usrp.
My UHD version is "UHD 4.3.0.0.-0g1f8fd345"
Can anyone help me to resolve this issue?
Thank you.
Eesa
