Nrf24l01 powering problem with LE33
I'm bulding a node (a motion captor) with an atmega328p and a 5v source
I want to use a LE33 for the VCC pin of the nrf24l01 but it's not working.
the debug log tell me that the radio is ok but I've a TSM Failure error and I can't connect to my gateway.
if i connect the VCC pin on the 3v out of a UNO card (that's the only thing a had for testing) its work like a charm.
I think i've missed something but I don't understand the problem
someone could help me a little bit?
@linkos did you connect a capacitor close to the nrf?
For power troubleshooting, see the flowchart at https://forum.mysensors.org/topic/666/debug-faq-and-how-ask-for-help
I don't test with a capa because I was thinking it was not necessary because it was working with the 3v of the UNO.
Thanks for the link. I'll try it tonight
What capacitor are you using?
I'll try with a 4.7uf. But actually I've not allready try it. I'll test tonight after work
4.7 uF is not enough, you need at list 10uF.
I had the same problem in my boards.
Ok thanks for your answer
