MySensors Raspberry port suggestions

I think there may be a memory leak in the gateway. While using it as a ethernet gateway I loose about 100Mb every day, if my only node is turned on. After a few days I can't even login with SSH and need to remove the power to my Pi3 to reboot it.

If I turn off my node, memory usage is normal. So it seems to have something to to when messages is received/transmitted. Is there anything I can do to get more details where the problem could be?

I'm using the image from Domoticz where everything is installed, and have only added mysGateway.

@raptorjr @hawk_2050 I'll check.
@b0rmann I'll do something about it.

@marceloaqno Hi, could you please explain to me what the steps are to compile it for RPi3?
I went here - https://github.com/marceloaqno/Raspberry
Downloaded and tried to compile. The following error has come up:

OK, I manage to install it finally.

However, again I have a problem:

./configure --my-gateway=ethernet --my-rf24-channel=1 --my-rf24-pa-level=RF24_PA_MAX --my-controller-ip-address=127,0,0,1

when I start it I have the following in the log:

Add some options to the gateway execution:

# ./examples_linux/mysGateway -h
Usage: mysGateway [options]

Options:
-h            Display a short summary of all program options.
-d            Enable debug.
-b            Become a daemon.

Debug is now disabled by default.
You can't run it as a linux daemon if debug is enabled.
When daemonized all messages will be print to syslog.

@marceloaqno Interesting. When I execute "mysGateway -h" I get the following:

pi@m:~/MySensors/examples_linux $ mysGateway -h
MCO:BGN:INIT GW,CP=RNNG---,VER=2.0.1-beta
TSM:INIT
Segmentation fault

What does "Segmentation fault' mean please?

marceloaqno

@alexsh1 You must be root to run the gateway:

$ sudo mysGateway

It seems that you are not using the latest version, -h should have shown you the options list.

alexsh1

@marceloaqno I have the latest version (downloaded yesterday). Thanks very much for your help. I got the following:

I added MySensors with LAN in Domoticz (port 5003), but here a problem. I can see the node and the GW communicating:

The RF communication is fine, but I do not understand why Domoticz is not assigning ID.......

EDIT: I can see in Domoticz in the Hardware section:

MySensors Gateway with LAN interface
Version: ? Setup

Typically ? comes up when the controller is not recognised or not connected

EDIT2:Deleted and started fresh. Unfortunately, now the log file is flooded with the following:

@alexsh1 There is a bug with --my-controller-ip-address, I'm not sure if it's your case, but try to avoid it.

I tried Domoticz here and everything seems fine:

MySensors Gateway with LAN interface
Version: 2.0.1-beta (Setup)

I recommend you to start from scratch, re-download the gateway from here:
https://github.com/marceloaqno/MySensors/tree/dev-raspberrypi

alexsh1

@marceloaqno OK, this must be the reason. I have tried the serial setup and it worked with a little tweak:

/dev/ttyUSB20 -> /dev/ttyMySensorsGateway

For whatever reason Domoticz did not see ttyMySensorsGateway so I had to create ttyUSB20

emc2

@alexsh1 said:

Domoticz seems to only look for ttyUSB* interfaces. One easy trick is to run ./configure with this option so you don't have to worry with symlinking

./configure --my-serial-pty=/dev/ttyUSBMySensorsGateway

BTW @marceloaqno , what does the option --my-serial-is-pty exactly do?
So far I've been running the gateway in ethernet mode for a little while and it's working flawlessly, thanks a lot for this port.

alexsh1

@emc2 said:

./configure --my-serial-pty=/dev/ttyUSBMySensorsGateway

Exallent fix! Thanks

@marceloaqno I can confirm that the Ethernet GW works fine without --my-controller-ip-address
MAny thanks for your port and help!

emc2

@alexsh1 said:

Just a guess, I see on your previous post that you used --my-controller-ip-address=127,0,0,1 it may have been a typo here, but did you try with --my-controller-ip-address=127.0.0.1? (dots instead of commas in the IP)?

alexsh1

@emc2 No, this is not a typo. This is a format. And yes, I have tried it with dots (127.0.0.1) - it did not compile.

emc2

Good to know then, thanks!

alexsh1

BTW, I am using a nice adapter for nrf24l01+ LNA+PA designed by @GertSanders :
https://www.openhardware.io/view/17/Raspberry-Pi2-GPIO-interface-for-NRF24L01

Works nicely with this port and RPi 3.

emc2

Same, I had one Pi with GertSanders adapter and now switched to the SMD versions to fit nicely in my case.
https://www.openhardware.io/view/105/MySRaspiGW
https://www.openhardware.io/view/116/MySRaspiGW-PALNA

Interestingly the regular one is working better than the PA+LNA version since moved to 2.0, at least in term of sending commands. Receiving is fine. Compiling with --my-rf24-pa-level=RF24_PA_LOW helps a lot. It seems 2.0 is really more power hungry, any hope to optimize this?

Which remind me of one thing, sorry to bother you again @marceloaqno (how) is the --my-rf24-irq-pin=<PIN> working?
I installed wiringpi to get rid of the wiringPiISR: Can't find gpio program but I'm not sure if it's supposed to do anything in the long term.
I was thinking updating the design of my PCB to link BCM 24 (pin 18) to the IRQ pin of the radio module but it's unclear to me if the IRQ will ever actually be used on the gateway.

marceloaqno

Those are cool adapters, I need to build one for me.

@emc2 It's no bother at all!
Using nrf24 IRQ pin can give you more throughput and less chance of losing messages. It makes more sense to use if you have many sensors or need to transfer binary data (https://forum.mysensors.org/topic/3594/solar-powered-observation-nesting-box-network/).

--my-serial-is-pty will simulate a serial port and create a symbolic link to it instead of using a real one.
