CE line on sensor node?
-
@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.

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

@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 IRQThese 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...

hello,
very good project!
I currently testing version 1.4b1 and I have a problem. Only if I disconnect the CE line on the sensor, the values are transferred.
If the CE line is connected, only one part will be sent, see Figure 1, the LED on the sensor remains on. As soon as I disconnect CE line, all values are not sent are transmitted (Figure 2) and the LED goes out and lights up briefly in the next transmission.Does anyone have an idea?
greeting

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:

inverted CE?

Pin 8?

@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/nRF24L01So the specs on that chip may be different. Maybe CE is inverted?

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.
-
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?
-
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?
