Wireless telemetry "Waiting for hearbeat" after a few runs

Hello,

So I’m facing this issue where I have to reboot my FC to connect to an ESP Dronebridge telemetry module after a few successful trial runs of the mission. My Python code connect to the drone and after a trial run, the program is closed. I can run the code a few times but then sometimes it gets stuck waiting for heartbeat.

Packet size: 128

Baud: 115200

Serial read timeout: 50 ms

Anyone know of a fix?
