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

[Grave]

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

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.

[mfalkvidd]

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

[Jan Gatzke]

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

[Grave]

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.
