Hello all, I hope the community is able to provide some assistance with this matter.
We've got a USRP B205mini-i and we're using it to test some Zigbee equipment we have on site to see how well it performs under a radio-noisy environment.
We've designed the GNURadio Companion file so that we can see a GTK spectrum in addition to sending the test signal out of the radio, however, when we try to observe the environment using an Ubertooth, the USRP does not seem to be putting out enough noise to get over the background noise of the environment, if at all.
Spectools does not show a substantial increase in noise around where Wi-Fi channel 11 would be, which is where our Zigbee equipment resides channel-wise, on channels 20-25.
Attached is the .grc file of our test setup. If someone could provide some insight as to what we might be doing wrong, that would be of substantial help. Thank you!
