Nice work @Branther The disadvantage is that the node won’t be performing all the stuff that normal nodes do. But since you don’t want that stuff for this particular node, there is no real disadvantage.

thanks again Edi. I will first make a full backup and put it on a new ssd. after that i will test your solutions as far as i can. sorry, i must have overlooked the code snippets function. best regards

Just for reference, as this solution was no yet mentioned: You could also use a second UART on your controller or a software serial for debuging with the following defines: #define MY_SERIALDEVICE Serial // Interface for controller connection #define MY_DEBUGDEVICE Serial1 // Interface for debug output Regards, Edi

super, once again a few super links, thanks for that i will go for the easy way. this sketch by boots33 works perfectly. But before that i will try to understand and learn the steps. thanks again branther

@Branther Thank you for your feedback!

yes, absolutely. i always order all my components from aliexpress. i don't think it makes any difference which dealer i use there. you can be lucky and sometimes not sometimes you can tell right away, for example an NRF module didn't have an IRQ. sometimes you have to search specifically to get the nrf24l plus model for example, which is different from the normal nrf module. in germany the parts are 3-4 times more expensive. so i put up with it. if you have several components, you can swap them and limit the error. thanks again
