Arduino UNO doesn't send packets?

[mitnickhun]

Hello!

I've an arduino uno and a mega. I tried the GettingStarted project without success.

Mega can send packets and uno can receive them, but mega doesn't receive the ACK's. I already switched the RF modules beetween arduinos with same results.

How can I find uot the problem? Mega doesn't receive or uno doesn't send?

I use arduino ide 1.0.5.

Any suggestions appreciated, Thanks!

This seems to be h/w issues instead of the RF24 libs issue... I read a lot of people have power issues with the Mega and solve it by putting a 100nF caps between Vcc and Gnd of the RF module... search for it in the Arduino Forum...

thank you! i found some solutions. the problem is with mega's 3,3V - it's not stable and that's the problem

Hello! I have the same issue with an arduino uno and an arduino ethernet. I have tried with 100uF cap but nothing changed. What is really strange is that if I perform R -> T -> R transitions on both consoles and than immediately the arduinos stat communicating. I found that the "radio.openWritingPipe(pipes[0]);" line was commented out into the setup. One un-commented the GettingStarted examples worked fine.
