Repeater failing?

[Steve Caster]

Hi all

I try to connect a repeater to my arduino but I get the following output...
000;t;0;0;3;0;9;send: 0-0-4-4 s=255,c=3,t=6,pt=0,l=1,sg=0,st=fail:M
to be honest, I do not have a clue why this occurs. When I plug it in with the serial gateway connected directly to my testing laptop it seems to do as expected, yet the moment I move it around I see this error
Any ideas?

Kind regards

Steve

st = fail
Seems to be radio/coverage
Have you added a capacitor to the radio or what radio do you use?

Hey,

can this be a power issue? When I connect it to the USB port it works fine, when I use my convertor from 220v to 5vdc , it gives me this error...

@Steve-Caster , yes it can be a power issue. Cheap phone chargers usually have high noise at its 5V output, for example.

Arduino itself is more tolerant to it, however the nRF radio is very sensitive to power noise/oscillation.

Sometimes just a capacitor between radio's VCC / GND helps. Have a look at the "Connecting a Decoupling-Capacitor" here
