💬 Building a Raspberry Pi Gateway

[gohan]

So far it looks to me it is something related to the latest versions of Linux since it was working on older releases

[Inso]

@gohan ah okay wasn´t aware of it, as the dev channel worked I assumed the bug at MySensors.
However, would be awesome if there were a little hint in the tutorial. Took plenty of time to find out it was an software incompability ;)

[arraWX]

A little hint in the tutorial would have saved me a lot of time too.

[gohan]

I added a comment; I hope my English is sufficiently clear :D

[Sergio Rius]

Today my rPi gateway (2.1.1 stable) completely stopped working as a service (cli surprisingly worked), I thought that could be some debian update so I switched to devel, but when building it I get this:

LINUX_ARCH_RASPBERRYPI -DMY_PORT=5003 -DMY_RX_MESSAGE_BUFFER_FEATURE -DMY_RF24_IRQ_PIN=18 -Ofast -g -Wall -Wextra -I. -I./core -I./drivers/Linux -I./drivers/BCM -c drivers/BCM/bcm2835.c -o build/drivers/BCM/bcm2835.o

^

Makefile:102: recipe for target 'build/drivers/BCM/bcm2835.o' failed

Is this normal? I used the same configure was working before.

@Sergio-Rius a fix is available at https://github.com/mysensors/MySensors/pull/983

It is a one line change so you can just add it manually

[Sergio Rius]

Thaaanksss! I'll give it a go :)

[Sergio Rius]

@mfalkvidd Mmmmm... that worked, but now I'm always getting "mysgw: !TSM:INIT:TSP FAIL" as stated avobe. But I'm on development.
Wait, seems that after the 8'th intent it's working. I'll let him go and see.

[Sergio Rius]

I'm afraid that after some time it stops working. I get in Domoticz:

Over and over again.

But it seems Domoticz being crashing it.
If I do restart the service, Domoticz picks it and works for a while.

Is there any further log for exactly seeing what is the crash cause?

EDIT: Also it seems that there's any comunication at all. I only get internal heartbeats on MysController.

[gohan]

Did you get the latest version from development branch?

[Sergio Rius]

@gohan Yep! I exactly ran this command:

git clone https://github.com/mysensors/MySensors.git --branch development && cd MySensors

I'm now powering off my rPi for changing the PA+LNA radio for a standard one and bypassing the power regulator.

EDIT: I've done the above tasks and still getting strange things. It may be Domoticz as:

[gohan]

If you keep a myscontroller connected to the gateway, does it stays connected or does it get disconnected at the same time as domoticz? Also try to run the gateway from console with debug enabled so you can actually see what it is doing

[alowhum]

Possibly same problem with Domoticz here too. Using a directly attached NRF24 radio to a Raspberry Pi Zero W.

I tried to remake using the latest dev code, and got this error:

Hello all!

I'm trying to build a gateway with a Raspberry pi2, ethernet and Domoticz.
It looks like the gateway is beeing built ok and seems to run fine but nodes can not communicate with it.
I have read most of the postings here but I can not find any solution.
Hope you guys can help? Please!

I run raspbian (Jessie)
pi@raspberrypi:~/MySensors/bin $ uname -a
Linux raspberrypi 4.9.35-v7+ #1014 SMP Fri Jun 30 14:47:43 BST 2017 armv7l GNU/Linux

Using master branch

git clone https://github.com/mysensors/MySensors.git --branch master

Configuring like this

pi@raspberrypi:~/MySensors $ ./configure --my-gateway=ethernet --my-port=5003 --my-transport=nrf24 --my-rf24-ce-pin=22 --my-rf24-cs-pin=24

  [OK] SPI driver detected:SPIDEV.
[SECTION] Detecting init system.
  [OK] init system detected: systemd.

Obs! No Raspberry identification, why not? Maybe that is the culprit?
After make I start the gateway and get this:

pi@raspberrypi:~/MySensors $ cd bin
pi@raspberrypi:~/MySensors/bin $ sudo ./mysgw -d
mysgw: Starting gateway...

mysgw: Client 0: 0;0;3;0;18;PING

Seems nice and dandy and Domoticz connecting fine.
Trying with this example node:

#define MY_RADIO_NRF24
#define MY_RF24_PA_LEVEL RF24_PA_LOW
#define MY_DEBUG
#define MY_NODE_ID 42
//#define MY_DEBUG_VERBOSE_RF24
#define MY_BAUD_RATE 9600

#include <MySensors.h>
#include<Arduino.h>

#define OPEN 1
#define CLOSE 0
#define CHILD_ID 1

MyMessage msg(CHILD_ID, V_TRIPPED);

uint8_t value = OPEN;

void setup()
{
  Serial.print("setup()\n");
}

void presentation()
{
  sendSketchInfo("Door", "2.1.1");
  present(CHILD_ID, S_DOOR);
  Serial.print("presentation()\n");
}

void loop()
{
  value = value == OPEN ? CLOSE : OPEN;
  send(msg.set(value));
  Serial.print("message sent");
  Serial.print(value + "\n");
  sleep(1000);
}

And recieve this when running:

And no output in gateway either.
Both radio modules using capacitors.

What have I missed?

Thanks, Andreas!

I tried for months to get a stable working nrf24 attached to pi to act as a gw and controller.

In the end I gave up and now have a 3.3V 8MHz pro mini gw attached to the pi. I took 0v and 5v from the pi (via a 3.3v buck converter) and serial tx and rx. Only 4 wires needed and has been as stable as can be for over a week now.

Maybe help someone with the same unsolveable problems?

[gohan]

@aglock I put a note on the raspberry gateway page to use latest development in case of problems with stable. Did you try?

[aglock]

@gohan yes. Interesting though when I used git to switch between branches it said all files where the same?
Do you think the fault is in the gateway somehow?

[aglock]

@gohan Tried it again
configure now recognizes the rpi:

pi@raspberrypi:~/mys_dev $ ./configure --my-gateway=ethernet --my-port=5003 --my-transport=nrf24 --my-rf24-ce-pin=22 --my-rf24-cs-pin=24

  [OK] SPI driver detected:BCM.

  [OK] init system detected: systemd.
[SECTION] Saving configuration.

[OK] Finished.

But make fails with the following error:

-I./core -I./drivers/Linux -I./drivers/BCM -c drivers/BCM/bcm2835.c -o build/drivers/BCM/bcm2835.o

What to do about it?

@mfalkvidd Wow, thanks that works! :D
