Multichannel (simultaneous) RX using LimeSDR

Hi all,

I’m in the process of trying to RX from the “A” and B" receivers using GNURadio Companion and the associated stack of API. I have single channel RX working just fine. My osmocom source block uses the “soapy=0,driver=lime,nchan=2” as discussed in another thread (https://discourse.myriadrf.org/t/two-rx-channels-in-gnu-radio/1234/5) but I am getting the error

RuntimeError: resolve_port: hierarchical block ‘source_impl’: output 1 is not connected internally

every time I attempt to run the code. I can’t see where I’m going wrong here. LimeUtils can locate and connect to the device without issue, and if I run single channel source (and remove the “nchan=2”) everything works fine.

Thanks everyone for your help
Cheers
Will
