CE line on sensor node?

Pin 8?

It looked like you could have a connection to pin 8, but apparently (in the better pictures) you haven't...

@aquapro I dont think you got a nordic semiconductor nrf24l01, What I can find they are only in QFN package.

So the specs on that chip may be different. Maybe CE is inverted?

[aquapro]

hm ... if CE inverted, ping sample should not work?! CE must switch between hight and low for TX and RX right? But Ping sample send and receive works.

Hi,

I have bought the new modules (right on pic), which operate without modification. I simply swapped and all is fine.
What do I do with the other. How can I test inverted.

@aquapro

I hope you didn't get the left one when purchasing through the links in the MySensors "store"?

[aquapro]

I got the left one from other eb..-"store".

[aquapro]

The left one works with MySensor-Coding, but only with disconnected CE line.

If it truly works correctly with CE disconnected, that could be an advantage when there is a shortage of pins (eg: 8 pin ATTiny).

Have you achieved full operation without CE on the old modules?

And did you leave CE floating or tie it high?

[aquapro]

I still see no difference when CE is disconnected.Only it as work at all.

[Zeph]

What vendor did you use to get the "no CE needed" variants? That could be useful to test.

I'm assuming that the nRF24L01+ doesn't work without CE connected, right?
