so i did some tinkering.
the readymade “pixracer” udp fw .bin would not let me connect to the http-console to adjust uart baudrate, so i chose to use the repository to build one to my needs (apm, 57600 on uart) with atom/platformIO. wasn’t a peace of cake for me as a non-coder, but it finally worked.
still dealing with uart-link-stability-issues due to the level-converter-setup, making it hard to successfully request the parameter list, but that just needs some soldering.
do you get access to the http-command-console with that .bin you linked?
