Situation has developed a bit. While browsing the forum I found this topic: [Link keeps dropping](https://discuss.cubepilot.org/t/link-keeps-dropping/1164) and decided to try the firmware versions that are proposed there. With them the remote and air units connect, I start getting telemetry data, and about 15 seconds later I get a “Connection lost” message. This happens every time I restart the drone. So far after losing the connection it was reestablished once and lost again in a few seconds.
