Step-by-step procedure to connect the NRF24L01+ to the GPIO pins and use the Raspberry as a Serial Gateway (MySensors 1.x)
-
I'm looking for some help in getting "PiGatewaySerial" running properly. I am having no issue running "PiGateway" and receiving all data from a counter node I'm using for testing. When I try to run "PiGatewaySerial", only intermittent data appears. For this example, I have my counter sending increasing integers at 1 second intervals, and receives fewer than 1 in 25 through the "PiGatewaySerial" script. I previously had this working reliably on a RPi2, reading in the tty output and logging it to a file. Now, I cannot repeat that on either that device, nor the current RPi B+ I'm working with. I'm sure there's some basic setting that I'm missing, but I can't seem to figure it out. Thanks!
An example of "PiGateway" correctly receiving all messages:

I have been thinking about giving this a try But:-
The Raspberry port is using protocol version 1.4.
Do the sensors also have to use version 1.4?@rmtucker
No, the sensors can be running 1.5 or 2.0-beta, the PI will run a 1.4 version.
The only thing not supported by the PiGateway is message signing.
But I have a mix of sensors in 1.5, 1.6-beta and 2.0-beta in my home network, so it certainly works. -

Adding support for signing on a pi gw should just be a matter of implementing random number generation and use software signing. With slight modification in the software signing backend as it assumes Arduino api:s for obtaining a seed for the rng.

Is it best to start with a blank jessie image and manually install/compile domoticz or just use the domoticz sd image?
The latter would be the easiest for me because i am useless with the CLI but if the first method is best??@rmtucker if you want to be able to run the very latest version of Domoticz, use the Debian image and compile Domoticz from git.
I use the Domoticz image. The downside is that I need to wait for new "official" Domoticz builds before upgrading, but the upside is that getting up and running was very easy.

@mfalkvidd
Actually ... I started with an official Domoticz build, and then I indicated in the settings that I wanted to update with the beta version. Since then I'm always on the latest beta (v5143 at the moment). -

@GertSanders cool. How often is the beta updated? Every build?
@mfalkvidd
Well, that seems to be the case. Sometimes I see daily updates, sometimes a week passes by without any changes. I selected the BETA channel for updates and since then I have seen new functionality come in on a regular basis. Not all of it is relevant to Mysensors of course, but none the less it's fun to see Domoticz is developed actively. -

Thing just purrs along. Will have to check when I get home but i believe my system uptime is approaching 1 year. It "just works" as they say.
I would like to upgrade to mysensors 2.0 library by it looks like the Pi repo has not being updated as often (last I checked, anyway).

@wergeld
Correct, the PI repo is basically unchanged. But it still is compatible with the 2.0-beta Mysensors library. -

@GertSanders What? I was under the impression that some features (like sending messages to nodes from domitcz wouldn't work).
@wergeld
Did not notice that, I can send values and "switch on" messages to nodes. The only thing I miss is the signing via ATSHA204. Even V_TEXT sending to and from nodes works. -
I have some trouble with the gateway not storing the network map, if i restart the gateway my non-sensor nodes need to send some kind of heartbeat to reconnect to the gateway.
Is this a known problem or is it something wrong with my setup?
-
Yes, known problem.
I had some hopes on @marceloaqno and @aaron832 providing a PR into development branch (so we can scrap the old RPI code). But there hasn't been any activity in a while.

https://forum.mysensors.org/topic/2759/mysensors-raspberry-port-suggestions/12@hek But insted of including heartbeats from every non sensor node (trying to keep 2.4 ghz traffic to a minimum), can i solve this by using an arduino repeater node? So the repeater knows the network map and sends heartbeat to the gateway.

@mfalkvidd I did the make clean and the make install and rebooted.
