💬 Building a Raspberry Pi Gateway

Seems I'm closing in to working solution. I didn't understand how to use the ./configure element before now. However I ended up with these configurations

I recommend you to test that everything is working before using the option --my-rf24-irq-pin=15Like this:
cd MySensors ./configure --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyMySensorsGateway --my-radio=nrf24 make sudo ./examples_linux/mysGateway -d -
Thanks for adding signing.
I want to use my rPi to generate random soft serials for my sensors.
Could all three "gen" commands output the line to put in SecurityPersonalizer.ino like it does when using the "set" commands? -

Hi,
Is there anyone here that can give me some one-to-one support this evening to setup the Raspberry Pi + NRF24L01 as a gateway with MyController, and a Arduino Uno + NRF24L01 as Sensor node. I'm stuck after trying various things over the past week, so looks like I need some additional skills/knowledge to get the first setup working.
Maybe we can use Skype or some other medium. I will gladly pay a bit for this support if anyone is interested. I have some free time from 18:00 CET - 23:30 CET today...
-
I have a gateway and 1 sensor ,obviously.
I have added serial GW but anyone sensor appear, i'm sure that the sensor works, and the gateway also (see with the command mysGateway -d).
Can you have any idea ? Thank you -

You can pretty much test out using any of the arduino examples here:
https://github.com/mysensors/MySensors/tree/development/examples
Each one will present itself to the gateway when it starts up and you will see the presentation in the debug log. Make sure to run:
https://github.com/mysensors/MySensors/tree/development/examples/ClearEepromConfig
on the arduino first to make sure it starts with a fresh eeprom. After you select an Arduino sketch to test it with (seriously it doesn't matter which one you try) make sure to look at the sketch and add:
// Enable and select radio type attached #define MY_RADIO_NRF24 #define MY_NODE_ID 4For MY_NODE_ID you can select any number. Just make sure that each new sensor node that you create has a different node number so like start out at MY_NODE_ID 1 and when you make another sensor node you can #define MY_NODE_ID 2 and so on.
Next load it up to the Arduino, open the serial monitor, and see what happens. If you watch the serial monitor on the arduino you will see it present itself to the gateway and then you can confirm it in the debug log on the raspberry pi.
I think it is pretty normal to have the problems you are having. I uninstalled and reinstalled the gateway 3 times on the Raspberry Pi before I finally got it all figured out. Once you get it running it is a glorious thing.

Ok,
I've tested with the Voltmeter and the NRF24L01 module do get a steady 3.26 V. Both the gateway module and the Arduino sensor node...
Im now building a few extra sensor nodes, so I can test without the Raspberry pi. Hopefully I can atleast get them talking based on Arduinos first. Before testing the Raspberry Pi.

Can I attach one or more DallasTemp sensors on the Raspberry Pi gateway?

Has anyone else had an issue with getting a sensor node to reconnect after a lost connection? I can see it attempting to reconnect but even though it is back within range of the gateway it won't reestablish the connection. If I reset the node it re-establishes the connection without any problem. This is the cycle that it gets stuck in:

@Christian-Simonsen multimeter will not detect issues with the power feed (noise or unstable). It just says that you voltage under zero load is 3.3V.

I haven't seen anyone doing anything similar so it might require some work. But almost anything is possible given enough work :)
@mfalkvidd Alright :) The thing is that I have my Raspberry Pi as a Gateway today near my server rack and would like to measure the temperatur. Maybe I just get a Nano to do the work for me. Just would have been great to use the Raspberry.
