When powered from usb, nrf24I01 is ok, from external Power not



  • Hi,

    I hope, you will understand my english.

    I have a sensebender micro. When I connect it only with a FTDI Programmer to watch the serial monitor, all is OK.

    But when I connect it to his power source, a LM2596S step down regulator, I get this on the serial monitor:

    0 MCO:BGN:INIT REPEATER,CP=RNNRA--,VER=2.1.1
    4 MCO:BGN:BFR

    8210 TSM:FAIL:CNT=1
    8212 TSM:FAIL:PDT
    18216 TSM:FAIL:RE-INIT
    

    On the gateway I get this:

    I have tryid it with an 10uf capacitor. But still nothing.
    
    Thanks Grave

    Welcome to the MySensors community @Grave !

    What capacitors do you use? The datasheet suggests 220uF.

    Have a look at the power troubleshooting flowchart here if you haven't already.

    Edit: sorry, I see now that you used a 10uF capacitor.

    It looks like the gateway restarts just after receiving the fpar message. Strange. What kind of gateway are you running?



  • @mfalkvidd I bet the serial gateway. 2.1.1 is bugy. I solved this problem by upgrading to the 2.2 beta from github.



  • I solved the problem. I have soldered a 1000uf capacitor to the output of the step down modul. Now everything is ok.
    I will try the beta Version.
