Sending "Hex-Code" and converting to uint32_t problem

[choffmann]

hi,

i want to send a "hex-Code" via FHEM to my arduino and convert it to an uint32_t for the FastLED-Method.

I have tried many methods like message.getString() or getCustom() and something like that. The Arduino gets the "Code" - But everything i tried to convert to an uint32_t wont work.

I hope you can help me with a code snippet or something like that.

Many thanks!
Christian
