not using this anymore for some years now. please try the dev branch where i blindly applied possible fixes.

from raspberry-remote.

Does anyone got it now ? I've tried everything but nothing worked

from raspberry-remote.

tried a quick & dirty fix in 13055a1 - as I dont have the hardware anymore, I would kindly ask you to report back.
