This script sends out a random chirp, then continuously listens out for chirps. It requires a [default] block to be set up in your ~/.chirprc file. See developers.chirp.io for further information.

If you want to select another block in the ~/.chirprc other than the [default], then pass in the block name with the -c argument. For example to select the [ultrasonic] block in your ~/.chirprc.

python3 example.py -c ultrasonic

The script will print out the available audio i/o devices, and point to the default audio devices. You may find that on some platforms you may find you need to explicitly set the input/output device. Use the desired device index with the -i and -o parameters accordingly to change devices.

There are also options to alter the block size and sample rate, however you shouldn't need to use these.
