FSK transmission between two Lime mini 2.0s

Hello!

I’ve been trying to transmit and receive data with two Lime minis via FSK demodulation. I’m using the GNU Radio FSK example (link here) as a template and modified it to transmit and receive to and from the limes. Currently, it seems to be transmitting as it can be seen in a frequency analyzer GUI, but it isn’t receiving anything from the Rx lime.

Here’s the flow graph for the TX lime computer (with LimeSuiteNG):

FSK_lime_TX
FSK_lime_TX3070×1679 378 KB

And here’s the flow graph for RX (with classic LimeSuite):

FSK_lime_RX
FSK_lime_RX1538×791 158 KB

Is there something I’m missing or parameters that aren’t quite right?

Thanks in advance!
