Setting up serial communication on UART 2

Hello!I am quiet new to ArduPilot, I started to work with it on code-level two month ago. Right now I am trying to send data through a serial port. It said, that UART 2 is free to use for own purposes. But when an other device was connected to UART 2, it was already receiving lots of data.I would be very thankful, if someone could provide some information on the data on UART 2 and whether there is a possibility to use an other port without affecting ArduPilots other system functions.Greetings

  • Thank you very much for your fast response!

    Do you know which message structure it is using? I tried 8-N-1 at 115200 Baud, but the output is not readable at all, changing the Baudrate hasn't changed anything.

    I am trying to find another port to use, but UART 0 is also sending data by default. Is there any other UART, that could be used?(I am using APM 2.6.1).
