Hi, I've been using your python script recently and I was able to successfully send commands to the RM Mini 3 and have them executed.

While working on this I was wondering if you made additional progress regarding the need to send a dummy command before every real command?

When capturing the traffic to the RM Mini there's no additional (other than the 'command') packet going directly to the RM and I was hoping we could get around having to send the dummy command to keep the RM responding.

Best regards, Alex

Hello!

I've managed to isolate a parts of an UDP payload that changes every time you send a command (and replaced them with random hex string), so, in the new version, there is no need for a dummy command.

Hi Davor, thanks for posting this info. In the meantime I found out the same thing when I looked more closely at the tcpdump output for repeated keypresses :) and I've also created a version, that randomizes parts of the payload. I didn't find the time to post it here, but your version is more elegant anyway.

Best regards, Alex
