💬 Building a Raspberry Pi Gateway

ccy

I am trying to connect NRF24L01+ and Raspberry Pi 2 (Model B+). I am confuse about pin 22/24 too. In the diagram it shows "SPI0 CS0" and "SPI0 CS1" but these two pins aren't exist in NRF24L01+. How should I connect the pin? I connect Pi2 pin 24 to CS and Pi2 pin 26 to CE (Not sure it is correct)? Here is the message from mysgw:

[root@alarmpi bin]# ./mysgw -d

@ccy Look at the chart below "NRF24L01+ Radio". That shows the PIN numbers on the Pi and the pin labels on the radio to interconnect. Pay no attention to the labels on the RPi generic pinout diagram except the PIN numbers. The RPi SPIO labels are not what you are looking for. And be sure to use the chart for the correct RPi model.

gohan

Exactly, I was about to write pretty much the same 😀

Grubstake

@gohan I beat you to it! :smiley:

@Grubstake: Thanks. I have tried to follow "NRF24L01+ Radio" pin out connection. I have double / triple check my wiring is correct. But I still get the same fail message in mysgw debug mode:

[root@alarmpi bin]# ./mysgw -d

Here is my /boot/config.txt:

gpu_mem=64
initramfs initramfs-linux.img followkernel
dtparam=spi=on

and the spi dev:

# ls /dev/spidev0.*
/dev/spidev0.0  /dev/spidev0.1

I am using ArchLinuxARM:

# uname -a
Linux alarmpi 4.9.13-3-ARCH #1 SMP Fri Mar 3 18:45:16 MST 2017 armv7l GNU/Linux

I only wiring 7 pins (1-7) on NRF24l01+.

Output from MySensors configure:

I finally find out my raspberry pi board isn't detected properly in configure. I change the function detect_machine:

function detect_machine {
...
    case $hardware in
...
    BCM2835)
        soc="BCM2835"
        if [[ $machine == "Raspberry"* ]]; then

            if [[ $rev == "a02082" || $rev == "a22082" ]]; then
                tp="RPi3"
            else
                tp="Rpi2"
            fi
        fi
        ;;

make mysgw again, and I get this finally:

I can run mysgw. But what can I use it for? I want to make it control my light with 2.4G RF. But I don't know what to do next. Please advice Thank you.

gohan

@ccy
You need to provide some more details about your hw and general setup, what have you done so far, log messages, etc.

ccy

@gohan Sorry for my typo mistake. I can now run mysgw. But what can I use it for? I am trying to control my light with 2.4G RF.

gohan

Do you mean your light has already 2.4G RF or do you need to make a relay node with NRF24 that can switch on and of that light? But this is going a little OT in this thread.

ccy

@gohan Yes. I want to do that. I am sure my LED controller is 2.4G RF. But I can't detect any signal yet from my nrf24l01+ on raspberry pi. I am not sure what's wrong. Still trying now...

gohan

@ccy
Being 2.4G RF doesn't mean it is NRF24L01 compatible also without knowing what channel is using will make it even more difficult. So, unless you want to make a Mysensors LED Controller, I think you are out of luck if you want to directly control your existing one with a RPI and the mysensors gateway. Either way this is OT.

ccy

@gohan Is there a way to know the channel by doing some sort of scan? If the channel is known, what are the setting to fix the channel for mysgw?

Hello everyone!

I'm using a Rasp2 (with the 40 pins GPIO header)

Has anyone experience with using the NRF module on different pins than default? I'm asking because I wonder if I can connect a GPIO-connected touch TFT (which would use the 2 CE lines for the touch and display interfaces) together with the NRF - by hooking the MISO/MOSI/SCLK to the default pins (and thus sharing them between the TFT and NRF) and defining free pins for the CE and CS lines in the ./configure script when compiling the gateway code...?!

Or maybe using the SPI1 by first enabling it as laid out in this blog post - but how to proceed from there? (How to tell the gateway code to use SPI1?)

marceloaqno

@Velo17

./configure --spi-driver=SPIDEV --spi-spidev-device=/dev/spidev1.0

(replace the /dev/spidev1.0 with the one you enabled in /boot/config.txt)

Hello Masters,

Could you please help me with setting up virtual serial port?

I can't see the interface created under /dev.
I'm using the instructions and finish with the setup with the following command:

pi@raspberrypi:/tmp/MySensors $ ./configure --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyMySensorsGateway
[SECTION] Detecting target machine.
  [OK] machine detected: SoC=BCM2836, Type=Rpi2, CPU=armv7l.
[SECTION] Detecting SPI driver.
  [OK] SPI driver detected:BCM.
[SECTION] Detecting init system.
  [OK] init system detected: systemd.
[SECTION] Saving configuration.
[SECTION] Cleaning previous builds.
[OK] Finished.

pi@raspberrypi:/ $ sudo /usr/local/bin/mysgw -d
mysgw: Starting gateway...
mysgw: Protocol version - 2.1.1
mysgw: MCO:BGN:INIT GW,CP=RNNG---,VER=2.1.1
mysgw: TSF:LRT:OK

mysgw: TSF:WUR:MS=0
mysgw: TSM:INIT:TSP OK
mysgw: TSM:INIT:GW MODE
mysgw: TSM:READY:ID=0,PAR=0,DIS=0
mysgw: MCO:REG:NOT NEEDED
mysgw: Listening for connections on 0.0.0.0:5003
mysgw: MCO:BGN:STP
mysgw: MCO:BGN:INIT OK,TSP=1

Everything seems to be OK. However, when I check /dev directory, the interface is not created.

What could be an issue?
Thank you in advacne!

gohan

Why don't you compile it as ethernet gateway?

engy

@gohan Etherner Gareway is not supported by OpenHab MySensors binding.

gohan

Mqtt? 😀

engy

@gohan I'm sorry, MQTT is not supported by OpenHab MySensors binding. Ethernet Gateway is not supported on Raspberry PI.

marceloaqno

@engy OpenHab2 supports mysensors serial and ethernet gateways:
https://github.com/tobof/openhab2-addons/wiki

Maybe the build guide may have given you that impression, but ethernet Gateway is supported on Raspberry PI:

./configure --my-gateway=ethernet
