Enabling Gains and Amplifiers in GRC
Posted: Tue Aug 27, 2019 8:07 pm
Hi,
I am currently working on a communications project utilizing two BladeRF 2.0 xA4 devices in a 2x2 mimo configuration. Unfortunately I can't seem to get very far into the project.
I am currently testing gains with the simple loopback example that was provided (I disabled the loopback feature and I seem to be receiving RF energy if I place the devices extremely close, otherwise I'm not seeing any signal).
I have been able to adjust the gain when I use the command line interface but I don't think adjusting the gains via the OSMOSDR source and sink blocks are working for me. I saw a couple of solutions in this forum but nothing that I have read seemed to solve my issue. Additionally, I can enable the BT-100 amplifiers via the command line interface but adding "biastee=tx" to the arguments list doesn't seem to enable anything (the blue lights do not turn on).
Any help would be greatly appreciated. Thanks.
