How to change the baudrate in RFD868?

Hi all,

I am using 2 RFD868x-EU and MatekH743 Slim V3 controller with the latest stable plane firmware (4.4.4).

I managed to setup a link with the default configurations (both ardupilot firmware and modems firmware). However the rate is very slow, in particular I achieve about ~1 kB/sec which under EU restrictions (max duty cycle 10%) seems reasonable. I also saw here that others face the same issue. So at least I tried to increase the baudrate from 57600 (default) to 115200. Unfortunately did not see much improvement. To do so I made the following changes:

Serial1_baudrate → 115
changed modems baudrate using rfdtools to 115200.
changed the ftdi cable baudrate to 115200 in device manager.

Am I missing anything? Shouldnt I be able to see the rate doubling approximately?

If you already used the modem tools and the above mentioned parameters you could bump up the air speed if you haven’t since you changed baud. this is my default setting for my radios which are rfd900x and 900ux series.
