Dear GNU Radio Community, I'm working on a GRC flowgraph, which has different variable blocks, e.g 'frequency' variable linked to the frequency parameter of signal source, and I have made a custom python block to receive the data as a float from serial port: 'COM4' by using the pyserial library, I want to equalize the 'frequency' variable with the float data coming from serial port, so that frequency value update according to the data coming from a port, but the issue is that 'frequency' variable is not recognizing as a variable, (variable not defined issue), is there any solution or any block that will update the variable 'frequency' with the variable 'frequency' defined in custom python block, because I want to control the frequency from the serial port. I am trying to do this on Windows, I don't want to go with OOT modules.
Kindly help me in this regard. Regards Muhammad Anas
