thx for your fast reply. i'm in the train right now. so i can't provide you now with any pics. as soon as possible i will do that!

I am using a battery booster (as it seems the same as you use), i have the battery jumpers connected, all the resistors and caps for the battery measurement.
It is just wired that it functions while the nrf24 is powered separately. maybe i got some bad radios?
One more question: the cap just below the booster. is this necessary to reduce the noice for the radio? might that help and if yes what size do you recommend? i didn't solder any cap yet there.

"Did you by any chance connect both batteries and ftdi Vcc at the same time?"
Yes! I did try this as well. Same results...
I should also mention i got my Arduino Pro mini battery powered hacked. So no more LED and Voltage regulator. But then again i also tried it with a untouched one.

just a quick update.

i ran some more tests with different radios and a 10uf electroltyte cap on the booster. And some different batteries.
Heureka! It works. For now. It is running now with a 3.7v lipo battery without the voltage regulator. Does anybody know if this is safe in the long run?

Thanks for clarifications

Awesome forum!

@flopp great setup! May I ask what controller you are using and how this works with getting the sleep time from the controller?

@sundberg84 do you experience the same thing when you are using boosters? Some are better than other even tough they are the same model? Same with the radios?

@gohan
just bought them on ali. What would you recommend in the meantime till they arrive here in snowy switzerland? i got a assortement of electrolyt caps.
i got a bunch of 0.1uf ceramics. could i just solder(or test it on a breadboard) 10 of them to try out?

ok. thanks for the tips and your promt assistance! such a great community!
i will try to experiment with some caps.
i tested already a couple of different radios. but maybe i will get once a decent one which will work

here are some pics form my pcb board!

Hi community!
i just got to fiddle around with my new newbie pcb and i ran into some problems.
I am already quite familiar with mysensors as i have built quite a couple of different nodes which are working very well (all on bread boards or selfmade pcb boards)
No i wanted to step up a bit and bought the newbie pcb boards.
I want to have a battery powered setup. So i did solder all the parts on the board. checked my wiring many times and also checked all components. I even did check the whole pcb board if every line is ok with a multimeter.

So my problem is:
all the time i debug my node (mockup sketch) with the Arduino IDE powered by battery, stable power source etc i end up having the error TSP failed.

when i leave my set up as is (i solders headers to the board to conveniently change the components ) and only power the NRF24 seperatly i get no errors. So it must be something with my power ?
but i don't get it where exactly my problem lies.
Could somebody help me?
