Mysensors Gateway on OrangePi (Zero) (opi)

jirm

I just see than on your previous compilation for NRF24 build from Tmr24h that you confirm is working OK, the compilation have same "bad" cpu type A53 that I figure that is a bad selection for H3 and seems that is not any problem...so now I'dont understand nothing..
Well mean only understand that we need a mysensor coder for help an guidance and if available make to it all the changes needed for OPI on mysenros.

So we need help for all.

As a side comment, posting interesting good info about Orange PI GPIO ports assignment and usage, that can help too:

Great info indeed, thanks! I will join the effort again when the OPi+nRF24 arrived. Just compiling without any hardware feels like baking a cake and not eating it...

@Tag The RF24 won't work on the OPi out of the box. Since the GPIO numbering is different it will work but only after some tweaks. I'm not sure if you're familiar with:
http://linux-sunxi.org/GPIO
Once you get the pin numbering figured out you can use the TMRh20 library. I confirm that it works on my OPi PC. Didn't unboxed my OPi Zero yet :yum:
However it's not very clear what sort of gateway you're trying to build. My project will have an OPi Zero running MyController, hooked up to an ATmega328 running the GatewaySerial sketch. The radio will be be connected to the ATmega328 chip. This way I wouldn't have to worry about GPIO pin numbering.

I'm using a orangepi one and with your help I can compile it.
I tried it with a serial gateway. I connected a arduino nano with the gateway serial scath on it through USB to my orangepi one. DMESG say to me, that it is attached to ttyUSB0
So i tried to build the gateway with:
./configure --my-gateway=serial --my-serial-port=/dev/ttyUSB0 --my-serial-baudrate=115200

make has no errors

after that, i tried to start it with:
sudo ./bin/mysgw -d

Is started but i get this problem:
(

Do you know whats wrong with it?

@hausinger: try to change

./configure --my-gateway=serial --my-serial-port=/dev/USB0 --my-serial-baudrate=115200
to
./configure --my-gateway=serial --my-serial-port=/dev/ttyUSB0 --my-serial-baudrate=115200

Be aware that USB devices are enumerated in the order they have been plugged in, so you cannot rely 100% on the arduino being "0".

@mihai-aldea: haha I didn't even consider this. are there any disadvantages except for the increased power consumption? (and slightly higher cost)

Hi again to all OPI users.

I like see that are great movements here.

I think main goal here is achieve that OPI board can run mysensors for herself connected radio boards.
Of course that can work OPI (or any board) if we attach over some port the radio board, because use of any "conventional" port (means usb, serial, eth) is the same for any hardware from the software view.

Said this, I would simplificate (and reduce all hardware to minimum) all things I can and with a powerful board I can concentrate much of the roles needed.
Attach directly (means through GPIO) all hardware the board can manage without issues is my goal, and I think other much people.

I think the error posted @hausinger for run mysgw seems derived from de main problem we see when try compile mysensors on OPI, and is that the need (maybe although not always necessary) that SPIDEV driver are up and working properly and mysensors software can not detect SPI bus (then fail SPIDEV) on OPI while is not being adapted all software stuff from some mysensor coder.

I hope some mysensors coder hear our call and soon can help here.

ooh sorry. Sure, i wrote "ttyUSB0". It was a typing mistake here on the forum. In my configuration I already typed ttyUSB0
I edited my last post.

But the issue is still the same.

@mihai.aldea

Indeed good info about GPIO port.

I will be aware about your progress...seems your approach is a sure win.

Thanks

In my case, why should it be necessary to have a working spi bus? I wanted to connect a working arduino with the mysensors gw scetch on it throug USB to the OPI and use this as a ethernet gateway.

My last goal is to use a USB to RS485 converter on my OPI (works as a Gateway) without a connected arduino, because my whole mysensors communication should be over RS485.

jirm

@hausinger

Of course you dont need any SPI bus.
And so sorry but before I checked so badly the error you posted.

Not seems any related working error for mysgw. I think you have mysgw working fine, seems only they can not connect/work with sensor node.

You seems only need check node communication and adjust node configuration to have your mysgw working.

I don't see you found so much trouble to make working from usb-rs485 adapter if you can do it with usb/serial node, it's only matter that the driver of adapter can work with mysgw without so much issues.

Thank you for your fast answer.
I try to answer it as best as I can.

I tried it once again:
connected the arduino to the USB port on my OPI
DMESG says it is port ttyUSB0

If i start the Gateway with:
sudo ./bin/mysgw -d

I got the same result as posted before. My CPU Usage is at 100% on one core.

if I kill the process of mysgw and start openhab2 (my used controller) it can connect direct to the Arduino (connected as USB as before) and it worked fine.

So my configuration of my nodes (currently only 1 for testing) is working fine through rs485.

Summary:
Connection node -> Arduino Gateway = OK
Connetion from openhab2 to Arduino Gateway = OK (openhab2 on same OPI as Arduino)
OPI as a Ethernet - Serial Gateway = NOT OK, Problem is shown on my screenshot.

USB-RS485:
I also tried this, but after my configuration:
./configure --my-gateway=ethernet --my-port=5003 --my-transport=rs485 --my-rs485-serial-port=/dev/ttyUSB0 --my-rs485-baudrate=57600
I can do the "make" command.
After that I start it with:
sudo ./bin/mysgw -d
I only get this:

I can now type a new command in the console (Gateway quit itself)

It should be a H2+, but I have seen H3 (think that was with an FTDI interface on the debug port....

@hausinger That shouldn't happen (gateway quitting itself). Could you submit the debug log with MY_DEBUG_VERBOSE_RF24 enabled?

Yes i can check that, but how?
I tried it to enable it in "example_linux" => mysgw.cpp (added the line "#define MY_DEBUG_VERBOSE_RF24")
I also tried it in the file: "MyConfig.h" (also added the line "#define MY_DEBUG_VERBOSE_RF24")

But my output is still the same in the console.

mihai.aldea

@Tag Just to make it clear, do you want to connect the RF24 radio directly on the OPi's GPIO pins? Or do you want to connect it first to an Arduino and then to the OPi?
I haven't used the mysgw because so far I only played with EasyIoT (directly attached RF24 to RPi GPIO - doesn't work on OPi) and MyController (using an Arduino connected to the OPi's serial port).
Since MySensors is open source you can definitely change the pin numbers to match the OPI's Sunxi pin numbering. I don't have a setup in place right now to point you in the exact direction but will cook one tomorrow and get back with the details.
Meanwhile you can burn the GatewaySerial sketch on your Arduino and either use /bin/mysgw or:

apt-get -y update
apt-get -y install minicom
minicom -D /dev/ttyUSB0

It's likely that the minicom will scramble the text on your screen but you can:

Ctrl+Z
O
Screen and Keyboard
T
Esc
Save setup as df1

Close the minicom window then open it again and all should be fine.

Hi!, my idea is to have the NRF24 radio directly attached to the GPIO header on the OPI, (got this already working on my RPI system). So the idea is to run mysgw on the OPI system.
(already got an extensive sensor network running with multiple arduinos and Mycontroller on thae RPI) On the RPI i had the arduino GW attached to USB and the NRF24 directly attached at the GPIO header at the same time, MyController saw 2 gateways :) )

The other option like you already mentioned is to attach the arduino using USB read from /dev/ttyUSB0. I see this as a last resort only if mysgw will never run on the OPI zero.

I read on the OPI website that the 26 pin header from the OPI is directly compatible with the RPI, however other sources of information tell me differently. So if you want to help out with the pin numbering this is greatly appreciated!

but again mysgw on the OPI with the radio on the GPIO header would be great!!

At this moment we try to build/compile mysgw on the OPI board, however that fails at the SPI part.

Thanks!

@hausinger The problem you are having with your serial gateway (./configure --my-gateway=serial --my-serial-port=/dev/ttyUSB0 --my-serial-baudrate=115200) may be related to this bug:
https://github.com/mysensors/MySensors/issues/720#issuecomment-270712256

@Tag I made the test setup and retraced my steps from the previous experiment. While the TMRh20 is working, the problem indeed lies with the ** mysgw** compilation. I'm getting the same error.
After spending quite some time trying to mitigate the errors I hit a wall and I concluded that the problem is not the different pin numbering but the mysgw source code. I believe the problem is the lack of support for this architecture and with MySensors being so complex and my C++ skills so average, I'm afraid I can't help.
However, if someone can mitigate the source code to successfully compile, the radio should be initialized with:
RF24 radio(7, 0);
7 - CE pin
0 - CS pin
More details here: https://github.com/TMRh20/RF24/issues/257

Thanks for the confirmation!!, now lets hope that mysgw, will be fixed/ported to the OPI boards soon!
would be great to expand the number of systems it will run on..
