💬 Building a Raspberry Pi Gateway

[skywatch]

That all seems to be OK - Always worth checking though if you ever get issues.
That means that I am lost for any ideas on why you have problems with ./configure>make>make install. It seems odd. Do you have another pi to try it on? That's the only thing I can think of now....even a cheap pi zero would be OK for a test.

I would still disconnect the USB hub and all the gpio wiring at the pi and see how it goes.

Good Luck! :)

@skywatch Unfortuntately not, it's only pi that I have.
No problem, better to check everything. I don't know if open in github, leave here, pass to arduino connected via USB.....

And.. for Arduino connected via USB, I need to abilitate something with raspi-config or the only thing to do is to connect and domoticz will read it? (of course with sketch gateway loaded on arduino!)

@OliverDog said in 💬 Building a Raspberry Pi Gateway:

Why do Tx and Rx Leds blink every 5 to 6 seconds?
Is it about communication between RPi and Gateway?
Is there a way to disable it and keep blinks only with nodes communication?

Is there an answer for that?
Thanks again

Hi and sorry for the question..
I have been trying to build a gateway with a raspberry pi 1 and a radio module nrf24 + for several days without success. .I am analyzing step by step what I can be wrong..
You can kindly indicate the exact command syntax ./configure I have to give?
thank you so much

Welcome to the MySensors community @pandy

./configure --my-transport=nrf24

should be sufficient. What results did you get from the make and sudo ./bin/mysgw -d commands?

[pandy]

@mfalkvidd said in 💬 Building a Raspberry Pi Gateway:

./configure --my-transport=nrf24

Hi and thanks for the quick answer..
This is the result of the command:

[SECTION] Detecting target machine.
[OK] machine detected: SoC=BCM2835, Type=rpi1, CPU=armv6l.
[SECTION] Detecting SPI driver.
[OK] SPI driver detected:BCM.
[SECTION] Detecting init system.
[OK] init system detected: systemd.
[SECTION] Saving configuration.
[SECTION] Cleaning previous builds.
[OK] Finished.

[pandy]

The result of the "make" command is very long ..

@pandy

On pi1 I cannot get a stable and re-doable configuration. See some post before.

I finally swith to Arduino connected via USB. WOrks like a charme. Probably an issue with PI1.

[pandy]

the result of sudo ./bin/mysgw -d is :

mysgw: Starting gateway...
mysgw: Protocol version - 2.2.0-beta

and it blocks..

[gohan]

@pandy that's definitely a problem. What linux are you using?

[sineverba]

@pandy Same my problem.
@gohan I did try also the DIETPI, how you did suggest to me some days ago. Only to say to @pandy let down the idea to use PI1. Use arduino usb/serial with your PI1.
I did use several nights.... :(

[pandy]

Thanks to everyone for the answers and suggestions...
At this point I think the problem is the raspberry type..
I will try the suggested solution above otherwise I will be forced to change raspberry ..
Thanks to everyone for help

[pandy]

@sineverba thank you for your suggestion..Do you have a link where I can find a tutorial for this system?
thank you so much

[gohan]

@pandy go for a new rpi3 that works very well.

Hello everyone!

I am trying to use a NRF24 module on the SPI1 of a Raspberry2 (so that I can also use a touch tft on SPI0).

I enabled it in the config.txt so that is lists under /dev/spidev1.0 - for conveniency I configured the CS0 to be at GPIO16=Pin36 (by using dtoverlay=spi1-1cs,cs0_pin=16).

I use the dev branch of MySensors.git as the master branch does not recognize my Pi. I used this configure line:

./configure --my-rf24-channel=124 --my-rf24-irq-pin=29 --my-rf24-ce-pin=31 --my-rf24-cs-pin=36 --spi-driver=SPIDEV --spi-spidev-device=/dev/spidev1.0

successful make
but when I run the gateway in the shell with sudo ./bin/mysgw -d, I get the following:

mysgw: Starting gateway...
mysgw: Protocol version - 2.2.0-beta

mysgw: digitalPinToInterrupt: invalid pin: 29

Any ideas what I can do to make it work?

[Velo17]

I think I might have found the root of the problem. The ./configure detects my Rpi2 as such (rpi2) but in the RPi.cpp in line 26 there is the pin to GPIO translation array and it is lacking translations for the high pin numbers - which is obviously wrong as on the RPi2 you have the extended GPIO connector with 40 pins...

const static int pin_to_gpio_rev1[41] = {-1, -1, -1, 0, -1, 1, -1, 4, 14, -1, 15, 17, 18, 21, -1, 22, 23, -1, 24, 10, -1, 9, 25, 11, 8, -1, 7, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1 };
const static int pin_to_gpio_rev2[41] = {-1, -1, -1, 2, -1, 3, -1, 4, 14, -1, 15, 17, 18, 27, -1, 22, 23, -1, 24, 10, -1, 9, 25, 11, 8, -1, 7, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1 };
const static int pin_to_gpio_rev3[41] = {-1, -1, -1, 2, -1, 3, -1, 4, 14, -1, 15, 17, 18, 27, -1, 22, 23, -1, 24, 10, -1, 9, 25, 11, 8, -1, 7, -1, -1, 5, -1, 6, 12, 13, -1, 19, 16, 26, 20, -1, 21 };

I copied the rev3 array to the rev2 array and compiled this and it seems to work in my case!

[wergeld]

@Velo17 Thank you! I had been pulling my hair out over this issue on installing a new RPi2 setup.

[mfalkvidd]

Adding link to the github issue (thanks for creating!) for future reference
https://github.com/mysensors/MySensors/issues/895

[Velo17]

I just noticed that mysgw is constantly consuming 95-100% CPU here. This even happens when I unplug the NRF24 module so that after starting mysgw basically nothing happens. Running development branch. Hmmmm. Any idea what to check?

[mfalkvidd]

@Velo17 strace might be able to help:

sudo strace ./bin/mysgw -d

Could you post your configure command? I'd like to try to reproduce the problem. I have a gateway with development from git as of about 2 weeks ago (a9418271) but I'm not using the nrf24. That gateway uses about 2% cpu on my Raspberry Pi 1. There have only been 6 commits since I built my gateway but I can update it and see if it starts acting up.

On my gateway, strace outputs loads and loads of these:

gettimeofday({1501098316, 668956}, NULL) = 0
ioctl(6, FIONREAD, [0])                 = 0
gettimeofday({1501098316, 671383}, NULL) = 0
gettimeofday({1501098316, 672447}, NULL) = 0
gettimeofday({1501098316, 673818}, NULL) = 0
nanosleep({0, 10000000}, NULL)          = 0
gettimeofday({1501098316, 685602}, NULL) = 0
getsockopt(6, SOL_TCP, TCP_INFO, "\1\0\0\0\0\7g\1P4\3\0@\234\0\0\250\5\0\0\30\2\0\0\0\0\0\0\0\0\0\0"..., [104]) = 0
getsockopt(6, SOL_TCP, TCP_INFO, "\1\0\0\0\0\7g\1P4\3\0@\234\0\0\250\5\0\0\30\2\0\0\0\0\0\0\0\0\0\0"..., [104]) = 0
gettimeofday({1501098316, 689179}, NULL) = 0
ioctl(6, FIONREAD, [0])                 = 0

Also, which git hash are you using? (git log -1)

Another thing to try could be to enable all the debug flags in MyConfig.h and see if they give you something interesting.
