[Tutorial] Raspberry Pi NRF24l01 direct connection
-
Hi @Daniel-Oliveira,
I've talked with @Anticimex and @thozza about it... We think it would be best to move the RPi build file and any eventual support libs into the main MySensors repo to keep it in sync with the rest .
Not sure if @thozza has begun working on some autoconf script or not (did you?). But I imagine he'd appreciate any help you can contribute with.

Hi. Thanks a lot for this implentation and the helpful posts here!I've got the gateway working with a tmp75 temperature sensor on an arduino. The nrf24 is sitting on the raspberry directly (CE pin 22), as a controller i'm using PiMatic. It works very nicely!
There is one small problem however. The PiGatewaySerial will only work if i have called PiGateway before (and closed it again). With working I mean picking up radio transmissions from my sensor node. Everything else seems normal (/dev/ttyPiGatewaySerial and radio details printout).
The details of both configurations might give a clue:

I'm at the point that i want to daemonize the gateway. Which in fact i did, but the same problem persists. Before i hack the startup script to first run and close PiGateway before PiGatewaySerial, i was hoping that someone has an idea what i'm doing wrong.
Thanks in advance!
solved!
I have two RPIs (a Pi 2 B and a Pi B+), which both worked with the pyRF24 lib of TMRh20, so when i had a look in the source of the radio initialization of PiGatewaySerial and found this:#ifdef __PI_BPLUS gw = new MyGateway(RPI_BPLUS_GPIO_J8_15, RPI_BPLUS_GPIO_J8_24, BCM2835_SPI_SPEED_8MHZ, 1); #else gw = new MyGateway(RPI_V2_GPIO_P1_22, BCM2835_SPI_CS0, BCM2835_SPI_SPEED_8MHZ, 1); #endifWhen i changed it to:
#ifdef __PI_BPLUS gw = new MyGateway(RPI_V2_GPIO_P1_22, BCM2835_SPI_CS0, BCM2835_SPI_SPEED_8MHZ, 1); #else gw = new MyGateway(RPI_V2_GPIO_P1_22, BCM2835_SPI_CS0, BCM2835_SPI_SPEED_8MHZ, 1); #endifand recompiled the gateways,it all started to work. After powerup everything runs :).
The Rpi that is connected now is the Pi 2 B. So i guess either i have my nrf25 wired differently then defined in this lib, or the precompiler was thinking i have a B+ connected. Or both.
I will find out when i get this also working on my B+. -
I'am trying to get this working on my Raspberry Pi 2 B with Raspbian but when using the setup.sh command I get this error:

Hello everyone! Great work here! I see this is still running the 1.4 protocol, is that right? I was able to get this working but only my temp sensors would respond. Anything where I had to send data wouldn't work.
Any chance of moving to 1.5 in the near future?
Thanks!

It might be a stupid question, but I've been staring at my screen for hours now, and can't find the solution.
How do i install/ connect this gatewatay in domoticz?I have a Raberry Pi (2) with domoticz installed, followd this tutorial and connected the NRF24l01 directly to the gpio, and according to the printout everything works.
So took a Arduino Uno, connected a magnetic doorsensor and a NRF24l01 and uploaded the right sketch, all ok and it even seems that the Raspberry is receiveing the data
But what kind of gateway do I select in Domoticz?
When I select Mysensors USB gateway I can't choose a serial port (seem legit since there is no usb connected), what hardware do I select?? -
@ArieKanarie Mysensors USB gateway is correct. I think you need to perform the steps mentioned in section "Enable the gateway for use with Domoticz" at http://forum.mysensors.org/topic/2437/step-by-step-procedure-to-connect-the-nrf24l01-to-the-gpio-pins-and-use-the-raspberry-as-a-serial-gateway?page=1

@mfalkvidd said in Step-by-step procedure to connect the NRF24L01 to the GPIO pins and use the Raspberry as a Serial Gateway.:
@Eawo Yes, it should work. I ran Domoticz and MySensors Gateway on my Raspberry Pi 1 when I first tried MySensors. If I remember correctly I had to connect CE to pin 15 instead of 22 but I am not sure why. Try using the same connections as on your Raspberry Pi 2 first, and switch CE pin if you get "check wires". Please report back here how it goes, so I can add the necessary information to the original post.
For what it's worth, this is correct. I'm currently running on a Pi 1 and put CE on 15.
I followed these instructions and it worked perfectly with no fuss: http://forum.mysensors.org/topic/1151/tutorial-raspberry-pi-nrf24l01-direct-connection

@mfalkvidd Thanks you very much sir!

make file has changes and there is no more librf24-bcm. Refer to the readme on the git and follow them

Hello all,
I hope someone can help with this.Is there any way to run the generated ./PiGatewaySerial application in the background? I've got mine to work perfectly but only if I SSH into my Pi and execute the app using "sudo ./PiGatewaySerial". I'm looking to run this as a background service/application. Whichever is easier.
Thanks in advance
