💬 Building a Raspberry Pi Gateway

[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:

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:

This is my config:

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

https://www.mysensors.org/build/raspberry
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...

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.
[SECTION] Detecting init system.
  [OK] init system detected: systemd.
[SECTION] Saving configuration.
[SECTION] Cleaning previous builds.
[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
drivers/BCM/bcm2835.c: In function ‘bcm2835_delayMicroseconds’:

make: *** [build/drivers/BCM/bcm2835.o] Error 1
pi@raspberrypi:~/mys_dev $ 

What to do about it?

[mfalkvidd]

@aglock see https://forum.mysensors.org/post/79403

[aglock]

@mfalkvidd Wow, thanks that works! :D

[Woeka]

Got mysensors gateway working on gpio of my Pi again using ./configure --my-transport=nrf24 --my-rf24-irq-pin=15 --my-leds-err-pin=12 --my-leds-rx-pin=16 --my-leds-tx-pin=18 --my-gateway=ethernet --my-port=5003

However on tx or tx always the two leds connected to pin 16 and 18 are lit. More people with the same problem?

[sineverba]

@Woeka There is (on Arduino Gateway) a function named "DEFINE INVERSE BLINK". Try to search for same for PI....

[romeo01]

Can we use the "debug ota log" features with the raspberryPi gateway ??

My node is not accessible and runs MYSBootloader.
My gateway is raspberryPI.

Now, I need to update the firmware on my node. Via MYSController, no problems, upload runs like a charm.

But how to do for debugging my sketch ? Some bugs appear...... , I need to take a look on some vars values.
Usually, I use the serial port with serial.print(some vars).
Which alternative I have to use without serial port, only OTA features ?

Thanks for the great work !!

[gohan]

Unless you are using an esp8266, I don't think you can remote debug a pro mini. @sundberg84 is working on a serial logger to microsd card, maybe it could help you in some way

[romeo01]

In fact, I do not need to log, but need to look what's happen in my sketch.
The new "OTALog" function, MY_OTA_LOG_SENDER_FEATURE or MY_DEBUG_OTA seems to be the good way.
From the docs, it allows to send a debug message to another node or gateway via OTA.

But how to got the debug message from OTA node, on the gateway side (RaspberryPi) ?

[gohan]

@romeo01 said in 💬 Building a Raspberry Pi Gateway:

MY_DEBUG_OTA

I'd start reading from here https://www.mysensors.org/apidocs-beta/group__SerialDebugGrpPub.html#ga6bd5956352d3a184a0cb02783b8d35ff

Well, you found the starting point !

MY_OTA_LOG_SENDER_FEATURE & MY_DEBUG_OTA are enabled on my OTA node.

Again the same question: What I have to do on the gateway side ?
Is it possible with the raspberry Gateway ?

I'm still looking for debugging my sketch in remote. I need to have a look on the debug messages. I reminder, the node is not accessible and runs MYSbootloader.

[gohan]

If I understood well, you need to set a target node ID that will receive the debug and then make a node with that ID in order to get the debug messages

[romeo01]

Exactly, but I would like to use the gateway (raspberry) as target.
Is that possible ?
If yes, how to display the debug message on the gateway.
I have an access to my gateway only via SSH.

[gohan]

I have no idea if can do it, but you could just have a node connected to USB port of the rpi and do a "cat" on the USB port and you can read the debug from the node
