@gohan debug output could be useful ;-)

I would have posted it but it just shows as no nodes are trying to connect and nodes are unable to find a parent of course. I'm using the rfm2nrf pcb in order to have the pins to connect to the raspberry.

PS here is the log of the startup

On my test RPI3 it is working.... I have to double check the other one.

@gohan Hi there updated to the latest dev, but i still have to restart the service after a few days, this is the message in the log:

Hello, I'm also have issue with this question. My Raspberry Pi 2 type is a01041, but by the original "configure" file it is not recognized:

[SECTION] Detecting target machine.
  [OK] machine detected: SoC=unknown, Type=unknown, CPU=armv7l.

Maybe someone could explain why it is not recognized?

"Configure" file lines:

function detect_machine {
...
    case $hardware in

        soc="BCM2835"
        if [[ $machine == "Raspberry"* ]]; then
            local rev=($(detect_rpi_revision))
            if [[ $rev == "a02082" || $rev == "a22082" ]]; then
                tp="RPi3"
            else

Double radio or alternative pin for spi1:

https://forum.mysensors.org/topic/7702/double-spi-radio-raspberry-pi/2

arraWX

I followed the instructions carefully. However I get an error. Can someone help?

git clone https://github.com/mysensors/MySensors.git --branch master
cd MySensors
./configure --my-transport=nrf24 --my-gateway=ethernet

This results in a warning:

[SECTION] Detecting SPI driver.
  [WARNING] No supported SPI driver detected.

When I run make I get the follwing error:

In file included from examples_linux/mysgw.cpp:74:0:

Hope someone can help. Thanks.

Maybe you didn't enable SPI on the pi.

From command prompt type 'sudo raspi-config', then select option 5 from the menu. This takes you to where you can enable the SPI bus on the pi. Then try again.

@skywatch Thank you! That solved my problem.

Hello friends,

Reading the instructions for building a RaspberryPi Gateway using RFM69, it states that one should use the development branch and not master, since the Pi is using a different version of the driver.

Anyone knows when this will be merged to master branch?

Also, since this forces all nodes to use development branch as well to be able to communicate with the gateway, assuming I use the development branch now and it is later on merged into master, is there an easy way to upgrade nodes remotely to the new code?

I am planning to use Wall Switch Insertable Node, and Mini Relay Mode - Both support OTA updates, am I correct to assume this will allow upgrading without taking the nodes out of where they are located?

Thanks!
Sefi

gohan

Like all nodes, you need to change the bootloader in order to enable ota.

hello, is there a inclusion mode planned for the raspberry pi gateway ?

Hi,
This seems a great job, but despite I had a look at many posts (yes, many out of the dozens of pages.. ;-) ), I still can't figure out some questions..

Beyond the obvious advantage of saving an arduino (and power supply, space..), is there an advantage for having the gateway hosted by the raspberry PI hosting my Domoticz ? (like more CPU available for handling communications or for signing ? or on the opposite more risks to overload the PI CPU -despite only a couple persons have complained about high CPU load))
the default setup is Ethernet. What are the pros and cons of ethernet vs serial setup ? (speed? reliability ? possibility to move to other gateway?..)
Is signing now implemented in this setup ? I didn't see it explicitely described, but some posts seem related to signing.
if I want to use an external antenna and the high power NRF24, should I use an aother power source than raspberry PI ? (or maybe sharing the same USB charger, but diverting the power in parallel of the PI ?)
is there a tutorial somewhere detailing how to uninstall and migrate to an external gateway ? During such migration, would I need to "touch" again my sensors and would I lose history logs of these sensors in Domoticz ?

Sorry for all these questions..

Not really. Cpu usage is normally 0-2% so it doesn't affect either way.

Switching between different gateway types (serial, ethernet, mqtt) can be easier since there is no need to re-wire anything, just reconfigure and recompile. But that could be done with a all-in-one Arduino setup as well.

Remote debug might be a benefit, since logging in to the raspberry pi to view log files can be done remotely. Remote debug for Arduino is possible, but usually requires additional hardware.

The raspberry pi has room for more logging, which can help troubleshooting.

The biggest downside is that a raspberry pi environment is infinitely more complex than an Arduino, which could affect reliability and make troubleshooting harder. On the other hand, there are more debugging tools available which might make troubleshooting easier.

the default setup is Ethernet. What are the pros and cons of ethernet vs serial setup ? (speed? reliability ? possibility to move to other gateway?..)

No difference in speed. No difference in reliability.

Ethernet can easily be made accessible over the network. Doing that with serial can be done but is a bit tricky.

Some controllers don't have support for all gateway types. See https://www.mysensors.org/controller for details.

Is signing now implemented in this setup ? I didn't see it explicitely described, but some posts seem related to signing.

Yes. See the help text produced by running ./configure --help

if I want to use an external antenna and the high power NRF24, should I use an aother power source than raspberry PI ? (or maybe sharing the same USB charger, but diverting the power in parallel of the PI ?)

Yes. See the note on https://www.mysensors.org/build/raspberry#wiring

is there a tutorial somewhere detailing how to uninstall and migrate to an external gateway ? During such migration, would I need to "touch" again my sensors and would I lose history logs of these sensors in Domoticz ?

See my answer in the question you posted yesterday.

Sorry for all these questions..

No worries. Except for posting one of the questions again (which wastes people's time and confuses people when they read only one of the places), you are very welcome to post as many questions as you like. Asking questions is usually the next best way to learn.

Thanks a lot for your clear explanations ! Very useful !
and.. bravo ! for all your work

Hi,
I'm trying to install the gateway on a Raspberry Pi 2 hosting Domoticz already (I had used the standard Domoticz image).
I receive an error message on the make step, but maybe I've not properly understood instructions (not very friendly with raspberry and linux environment).
First, I wired the NRF24 with PA (meaning I used an adapter and the 5V physical PIN#4) and the IRQ (wired on physical pin #15)
Then I logged into my raspberry and staid in initial directory (pi@raspberrypi )
I then typed:

pi@raspberrypi ~ $ git clone https://github.com/mysensors/MySensors.git --branch master
Cloning into 'MySensors'...
remote: Counting objects: 14895, done.
remote: Compressing objects: 100% (8/8), done.

Resolving deltas: 100% (9022/9022), done.
pi@raspberrypi ~ $ cd MySensors
pi@raspberrypi ~/MySensors $ ./configure --help

Hopefully I did it in adequate folder ? (now I see a Mysensors folder in my /home/pi folder).
Then I typed:

pi@raspberrypi ~/MySensors $ --my-transport=nrf24
-bash: --my-transport=nrf24 : commande introuvable
pi@raspberrypi ~/MySensors $ ./configure --my-transport=nrf24
[SECTION] Detecting target machine.
  [OK] machine detected: SoC=BCM2836, Type=Rpi2, CPU=armv7l.

  [OK] SPI driver detected:BCM.
[SECTION] Detecting init system.
  [OK] init system detected: sysvinit.
[SECTION] Saving configuration.
[SECTION] Cleaning previous builds.
[OK] Finished.

So far, no error.. but should I have typed "./configure --my-transport=nrf24 --my-rf24-irq-pin=15" to implement the IRQ ? If yes, can I retype that command with new settings without issue ?

Then I understaood I had to run make command:

pi@raspberrypi ~/MySensors $ make
gcc -MT build/drivers/Linux/log.o -MMD -MP -march=armv7-a -mtune=cortex-a7 -mfpu=neon-vfpv4 -mfloat-abi=hard -DMY_RADIO_NRF24 -DMY_GATEWAY_LINUX -DMY_DEBUG -DLINUX_SPI_BCM -DLINUX_ARCH_RASPBERRYPI  -Ofast -g -Wall -Wextra  -I. -I./core -I./drivers/Linux -I./drivers/RPi -I./drivers/BCM -c drivers/Linux/log.c -o build/drivers/Linux/log.o
cc1: error: bad value (cortex-a7) for -mtune switch
Makefile:118: recipe for target 'build/drivers/Linux/log.o' failed
make: *** [build/drivers/Linux/log.o] Error 1

But errors... :anguished:
I tried to search on forum, and saw someone else meniotning a smilar error, but people were answering about OrangePI, whereas I use a Rasp PI 2.
I probably misunderstood some steps.. Could someone help me ?

Note: in instructions, there's a statement I don't understand for ethernet gateway: "To set the gateway as a client that connects to a controller, use:--my-gateway=ethernet --my-controller-url-address=YOUR-CONTROLLER-ADDRES" . IN which case do we need that ? (as said, I plan to simply use this gateway on My dodmoticz rasp PI).

Ricorico94

@ricorico94 said in 💬 Building a Raspberry Pi Gateway:

./configure --my-transport=nrf24 --my-rf24-irq-pin=15

That is fine, no need to add extra parameters as by defaults it will configure as ethernet gateway. Also try using the development branch as it has lots of bugs fixed.

@ricorico94 Yesterday I managed to make a working rpi gateway. I am on rpi3, use a socket adapter board for the radio and use domoticz. I posted all the details here: https://forum.mysensors.org/topic/7793/nrf24l01-problems-in-2-1-1-and-2-2-0-beta/24

ricorico94

Hi,
@arraWX : I looked at your post. Unfortunately, the error I face is before the start, as it's during the make, so it appears I follow the first steps you describe (config & make), but I still don't know how to solve the make errors.

In case it can help understanding what's going on or what to do, I ran the command:

gcc -v

which displayed: gcc version 4.6.3 (Debian 4.6.3-14+rpi1)
Could it be an issue this "+rpi1" whreas I've a PI 2 ?

arraWX

Do not know if it is of any help, but mine says: gcc version 4.9.2 (Raspbian 4.9.2-10)
