[Tutorial] Raspberry Pi NRF24l01 direct connection
-
(solved)
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
