[SOLVED] Node does not connect to gateway



  • Hi,

    im working on a little project with two dimmable LEDs, analog to
    https://www.mysensors.org/build/dimmer.
    MySensors version is 1.54

    On my protoboard everything works perfect.
    That‘s what‘s the arduino tells me on start up via its serial port:

    send: 0-0-0-0 s=255,c=3,t=15,pt=2,l=2,sg=0,st=ok:0
    send: 0-0-0-0 s=255,c=0,t=17,pt=0,l=5,sg=0,st=ok:1.5.4
    send: 0-0-0-0 s=255,c=3,t=6,pt=1,l=1,sg=0,st=ok:0
    sensor started, id=0, parent=0, distance=0
    send: 0-0-0-0 s=0,c=0,t=4,pt=0,l=0,sg=0,st=ok:
    send: 0-0-0-0 s=1,c=0,t=4,pt=0,l=0,sg=0,st=ok:
    send: 0-0-0-0 s=255,c=3,t=11,pt=0,l=13,sg=0,st=ok:Greenhouse_1A
    send: 0-0-0-0 s=255,c=3,t=12,pt=0,l=3,sg=0,st=ok:1.0
    send: 0-0-0-0 s=0,c=2,t=3,pt=0,l=0,sg=0,st=ok:
    send: 0-0-0-0 s=1,c=2,t=3,pt=0,l=0,sg=0,st=ok:
    read: 0-0-0 s=0,c=1,t=3,pt=0,l=3,sg=0:0.0
    Changing level to 0, from 0
    send: 0-0-0-0 s=0,c=1,t=2,pt=2,l=2,sg=0,st=ok:0
    send: 0-0-0-0 s=0,c=1,t=3,pt=2,l=2,sg=0,st=ok:0
    read: 0-0-0 s=1,c=1,t=3,pt=0,l=3,sg=0:0.0
    Changing level to 0, from 0
    send: 0-0-0-0 s=1,c=1,t=2,pt=2,l=2,sg=0,st=ok:0
    send: 0-0-0-0 s=1,c=1,t=3,pt=2,l=2,sg=0,st=ok:0

    If i plug the same chip and the same NRF24L01+ on my etched board, the only thing it tells me on start up is:

    send: 0-0-0-0 s=255,c=3,t=15,pt=2,l=2,sg=0,st=fail:0

    I checked for hours all the connections, soldered capacitors on all possible places and now i run out of ideas. Has someone a tip, what this line wants to tell me?

    Aloha, FlorenzW



  • Solved. 100nF at the NRF24L01+ was not enough. With a 4,7µF tantal-C added it works.

    Aloha, FlorenzW
