So if someone knows how I can implement a callback or a polling function to make the device tune for real, but as fast as possible, that'd be very helpful.
In the past, I've done external tuning via GRC with the following: Create a variable block (ie - "frequency"), and put the name in the frequency parameter of the UHD-sink block. Create a subgraph consisting of a UDP source block and a variable sink block, aimed at the "frequency" variable. Use an external program to send a UDP packet to the port number of the UDP source block. The packet should contain a single integer representing the frequency. Pay attention to byte-order. I've used this setup to apply doppler correction from an external program when receiving telemetry from a spacecraft. We were only sending packets about once per second, so I don't know how fast this setup will go, but it's worth pursuing. @(^.^)@ Ed _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
