We need to implement Pitch - Catch functionality with three total devices. Further, we are implementing this with EV MOD versions of the -02 devices, which have been shipped to us from TDK with matching frequencies as required. Our understanding is that these need to be programed for either Pitch functionality or Catch functionality. Given that, we are not able to find details of where to locate the appropriate source code, nor how to execute. We are able to find the appropriate APIs to implement, Hardware triggered, single shot CHIRP.
