- using Cube Orange and ads-B carrier board
- Firmware: Arducopter 4.0.0
- MP Version: 1.3.70
- set parameters

- ADSB\_ENABLE = 1 Enable ADS-B (Disabled as default)

- SERIAL5\_BAUD = 57 Set baud rate

- SERIAL5\_PROTOCOL = 1 Set protocol

- SR1\_ADSB = 2 Set ADSB stream rate to ground station on Telem2

but I can’t see any airplane around me (tested air traffic with flightradar24). With singe uAvionix ADS-B ping it works fine. Any hints what can be wrong? How can I check heartbeat of the internal ADS-B?

Are you outside? Clear line of sight?

Yes, was outside at the same place where the uAvionix Ping works well.

Go for a fly, and compare results. Range should be around 10 miles.

If you are still not receiving any, then RMA it
