Requesting device_data from ping360 results in an empty profile:

[patrickelectric]

device_data = p.wait_message([definitions.PING360_DEVICE_DATA])

I am also having issues getting data from the Ping360.

I'm not sure if I am "starting the sample" correctly. Should I be using:
ping.control_auto_transmit(start_angle, stop_angle, num_steps, delay)

OR, call this method in a loop like the example:
ping.transmitAngle(angle) (or maybe both? there aren't many comments in the ping360.py example and It's difficult to get visibility into what is going on behind the scenes.)

To retrieve the data I have tried the following two methods:
ping.wait_message([definitions.PING360_DEVICE_DATA])
ping.get_device_data()

the wait_message() method is returning None every time
the get_device_data() is returning something that looks like:
{'mode': 0, 'gain_setting': 0, 'angle': 398, 'transmit_duration': 32, 'sample_period': 80, 'transmit_frequency': 800, 'number_of_samples': 200, 'data': bytearray(b'')}

Any ideas? I don't have the version I'm using (I usually print brping._version__ but that seems to be missing.)
If there is an older version of ping-protocol that has the Ping360 portion working could you link me that branch/commit? We are planning to deploy the Ping360 in a system end of next week and I could have sworn I had the Ping360 working in the past.... I'm happy to submit the code I am running to get this behavior if that would help!

Thanks!
