Raspberry GPIO NRF24l01+ make error

[Vladut Grecu]

@sj44k
Tell me where did you connected the CE Pin on rPi..
Do you have another Arduino so you can burn a serial gateway into it? So we can be sure that your Mega is sending and receiving properly?
From your Arduino output he clearly does not link with the nrf on the Raspberry.

[sj44k]

Checked the wires 5 times .. all looks well. CE is on pin 15
Arduino should also be ok, I get error messages (Check wires) when it's connected differently

(Heres the Arduino mega pinout as I used it
http://forum.mysensors.org/topic/249/arduino-mega-sensor-shield-2/2 )

I have an Uno ordered but at this moment I am stuck to 1 arduino
I do have an extra Pi which I could use ..

By the way, where would I receive the information on my pi in this example (in case it would work)
?
in the screen where I started the
./PiGatewaySerial

Or in a cat /dev/pts/1 ?

[Vladut Grecu]

Move the pin on 22. The actual 22 pin not gpio22. Full restart the pi.

I think you can cat the /dev/ttyMySensorsGateway. In the way I use it(with pimatic) all the commands are logged.

[sj44k]

Tried that too, not working. But I now see why you asked that my output when starting PiGatewaySerial shows :

CE Pin           = Custom GPIO25

So that needs to be harware pin 22

This picture helped a lot and makes now that I am 100% sure my Rpi is hooked up correctly.

:s: must be overseeing something realy simple / stupid .. :/s:

Guess it must be the Arduino Mega causing the issue, back to my drawingboard .. will keep you posted

[edit]

Just found an interesting SPI reference picture for my Arduino Mega

My Pinout seems to be ok on the SPI side, just need to check CE / SE in regard to the scketch/libraries I am using.

Radio 1 GND Paars Arduino GND
Radio 2 3v3 Blauw Arduino 3,3v
Radio 3 CE Groen Arduino 48
Radio 4 CS Geel Arduino 49
Radio 5 SCK Oranje Arduino 52
Radio 6 MOSI Rood Arduino 51
Radio 7 MISO Bruin Arduino 50

[sj44k]

YEAH !
It works !! thanks for pointing me in the right direction !
Arduino needed the right scketch uploade (I messed so much with it I needed to go back which I just did)

As a reference for all who are trying to get this to work.

Use this pinout for the RPI B+
Radio 1 grijs GND Rpi 25
Radio 2 paars 3v3 Rpi 17
Radio 3 blauw CE Rpi 22
Radio 4 groen CS Rpi 24
Radio 5 Geel SCK Rpi 23
Radio 6 oranje MOSI Rpi 19
Radio 7 Rood MISO Rpi 21

Arduino Mega
Radio 1 GND Paars Arduino GND
Radio 2 3v3 Blauw Arduino 3,3v
Radio 3 CE Groen Arduino 48
Radio 4 CS Geel Arduino 49
Radio 5 SCK Oranje Arduino 52
Radio 6 MOSI Rood Arduino 51
Radio 7 MISO Bruin Arduino 50

I used the Libs mentioned in the post above by Vladut Grecu :
https://github.com/mysensors/Raspberry

I used this Temperature sketch :
http://www.mysensors.org/build/temp

Before I did got the Temp sketch operational I needed to clear my EEprom :
http://arduino.cc/en/Tutorial/EEPROMClear

/*
 * EEPROM Clear
 *
 * Sets all of the bytes of the EEPROM to 0.
 * This example code is in the public domain.

 */

#include <EEPROM.h>

void setup()
{
  // write a 0 to all 512 bytes of the EEPROM
  for (int i = 0; i < 512; i++)
    EEPROM.write(i, 0);
   
  // turn the LED on when we're done
  digitalWrite(13, HIGH);
}

void loop()
{
}

Than we need to edit the sketch a bit due to the fact that the Rpi gateway DOES NOT hand out the Node ID's automaticly, and the Sketch is not Arduino Mega compatible so :

Set the Node ID manualy add

gw.begin(NULL,10,false);

Make sure the sketch is compatible with the Arduino MEGA pins (as published abover here)
Change Line 12 in the sketch :

MySensor gw;

into

MySensor gw(48,49)

Than compile and hook everything up and upload the compiled sketch and start the Rpi (SPI enabled) and start
./PiGatewaySerial

Output should show on your Pi when you
Cat /dev/ttyMySensorsGateway

Big Thank you to @Vladut-Grecu !

Just received a great pull request for the Rapsberry created by @Holger-Meyers .

https://github.com/mysensors/Raspberry

I had it finally working on my Pi2, but its very unstable. sometimes weird values, crashes and fails.

switched to a usb serial arduino and that works great.

[Andreas Maurer]

The original code on github is a bit buggy. Thats right. But the actual code after Holger has reworked it is running well.
I am using it for nearly a month now. Nothing has crashed after Holger has looked after the reason why.

Currently I am happy with the stability.

[Sander Teunissen]

@Andreas-Maurer Could you tell me which controller you are using for your setup ?

Thanks !

[Andreas Maurer]

I am using fhem on the same PI. connected over the pseudo serial port.

[blksun813]

What is the CPU usage of PiGatewaySerial when you look at top? Mine is using 97%.

[Andreas Maurer]

It isn´t on the list :)

[blksun813]

Thanks.. Looked again today and it has calmed down.. Maybe it's just at start-up before there are any messages received or maybe something reading the Serial Port.
