Hi Del,
We hope you had a great weekend! It sounds like there could be a few reasons why your audio is not recording.
1) We recommend connecting your beacon to your vehicle first, then connecting the phone to the beacon.
2) You'll want to ensure your phone is running the app throughout the flight. If your phone was locked or in any sleep mode the app may have stopped running during your flight.
3) As you know, the audio will only record through the mic on your smartphone. When flying, try to turn off the wifi on your phone to make sure that the phone will not auto-connect to the vehicle wifi while using the beacon.
4) With the audio files on the SD card, you may want to confirm that multiple clips that you expected to show on the SD card weren't merged into the same audio file (i.e. two video clips had one longer audio file).
We hope this helps! Thank you for your patience through troubleshooting. Please let us know if you continue to experience difficulty after following these steps.
We're happy to have you flying with us!
Best,
Ralph
