Added a capacitor, same result - but Stuntteam you are so right! I also remeasured voltage on the level converter and it only delivered 2.2V, tried another level converter (same type) one and bingo it all works! Guess the first one is for the garbage bin now. Many thanks!

Missed the connection of mega pin 6 to gnd; now the output looks better, but the cc2500 is now reported as "missing": 20;00;Nodo RadioFrequencyLink - RFLink Gateway V1.1 - R48; 20;01;MySensors=OFF;NO NRF24L01; 20;02;setAnsluta=OFF;NO CC2500; 20;03;setGPIO=ON; 10;version; 20;04;VER=1.1;REV=...

Is there some way to check the response from the cc2500 or check if the module is defective? I believe the level converter is correctly installed, I have measured correct voltage 3.3V at gnd/vcc on the cc2500, I do not know how to check the other pins unfortunately. It should be a simple installatio...

Hi, Possibly something I am missing (ridiculously new to this), but I cannot activate the Ansluta protocol (nor LivingColors, BLE, Mysensors). This is the output in Rflink Loader: 20;00;Nodo RadioFrequencyLink - RFLink Gateway V1.1 - R48; 20;01;MySensors=OFF;NO NRF24L01; 20;02;setGPIO=ON; 10;version...
