CE line on sensor node?

[Yveaux]

Can you check with a different radio and/or Arduino?

[aquapro]

Yes, checked with 5 Arduinos (all different vendor's) and 8 radios. Same Problem. I am totally confused.

@aquapro

Have you tried all new wiring?

[hek]

If you show a few pictures also (closeups!) it might help.

[aquapro]

If I disconnect orange wire (red marker on first sensor picture), sensor works fine.

I think I would connected the radio directly to the breadboard pins next to the Arduino with new wiring.

@aquapro sagte:> Hi,

I have tested 1000 times, wasted complete weekend. Rechecked with built up the wiring from scratch. Same Problem.
Suppose I have swap the cables, which I doubt, why it works when I disconnect it completely?

I have all the cables replaced, also new from different suppliers. I used the next pins on the Arduino. For the pictures I have to build something stretched to better overview.

@aquapro
So the pictures don't reflect the current wiring?

[aquapro]

Pictures reflect the curren?t wiring! Same Problem with closer wiring

[Yveaux]

@aquapro The MySensors site (http://www.mysensors.org/build/connect_radio) gives the following wiring:

Arduino     nRF24
9           CE
10          CSN
13          SCK
11          MOSI
12          MISO
2           IRQ

These are the defaults for the library. CE & CSN you can adapt through the constructor of MySensor (did you do that?)

Looking at the pictures I have a hard time figuring out the connections for pins 8..12, while these are just the interesting part...

@aquapro Hmmmm
The chip on your looks like a blob more than this; You might have gotten a chinese ripoff .. I dont remember the chip name... Hmmmm hard to see!

edit:

maybe : http://forum.mysensors.org/topic/300/rfm73-experience/ ?
inverted CE?

[Yveaux]

@Damme Sharp observation, dude!

Have a look at these: http://www.aliexpress.com/item/Free-shipping-10pcs-lot-NRF24L01-wireless-data-transmission-module-NRF24L01-wireless-module/1996222121.html

Claimed to be nRF24L01+!!

@Damme
Nice Catch Indeed!

[aquapro]

@Yveaux yes I checked wiring with (http://www.mysensors.org/build/connect_radio)
more detail picture, hope so. (bad light)

@Damme
Chip is covered.

Pin 8?

[Yveaux]

@aquapro said:

Pin 8?

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

[Damme]

@aquapro I dont think you got a nordic semiconductor nrf24l01, What I can find they are only in QFN package.
http://www.nordicsemi.com/eng/Products/2.4GHz-RF/nRF24L01

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.

[aquapro]

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"?
