💬 Building a Raspberry Pi Gateway
-
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!

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?
@Velo17 strace might be able to help:
sudo strace ./bin/mysgw -dCould 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]) = 0Also, 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.

@mfalkvidd I make / make install a couple of times and maybe did a git pull inbetween as well - now everything is back to normal again. Thank you for giving me some dbug tips for the next issue :-)
My strace output looks similiar.
My configure line is
./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 --my-debug=disable -
Should be possible to connect two radio modules and run two instances at the same time?
It could be interesting to have a hat with nrf+rfm, all in one. -

An earlier discussion on the same topic: https://forum.mysensors.org/topic/4151/nrf24l01-and-rfm69-on-one-gw/So far, people have found it easier to add a separate gateway for each transport.

@mfalkvidd thanks for guiding me on the starting point. Perhaps the raspberry can break the doble transport limitation.
I'll investigate in how to install two services at once. But it'll would be nice any advice on the device virtualization part. -
Maybe it could be as simple as running two instances of mysgw, using different pins for the nrf and the rfm?
@mfalkvidd Maybe. I'm programmer, but not for Linux. My concern is the part of the service that creates the virtual device colliding between the instances.
I'll do a test in a virtual machine as soon as I have some time.
It should be something easy to test. -

@Sergio-Rius by "virtual device", do you mean the com port? If that's the caee, it can be specified with --my-serial-pty=
Ot let one gateway be serial and the other ethernet.
@mfalkvidd yes. Should work. I admit I've not taken a look at the code nor I don't know how to install the service two times.
I'm used to having problems with programs that use static resources allocation. But I don't know if that's the case. -
Hi guys couple of questions, apologies if they have been covered elsewhere.
I am running latest dev branches of domoticz and MYS on a pi2.
At random times it seems the NRF24L01+ LNA/PA goes down, or MYS goes down and domotics stops receiving signals from all of the nodes at the same time. I have the interrupt feature enabled.
I have set the option under domoticz/hardware/data timeout to restart if no data received in five minutes but I dont think this is an ideal solution, and have yet to find out if this domoticz feature actually works in my scenario.
Any idea what causes this? I found an old thread over on the domoticz/mysensors forum but no answers there. I am using a new sd card class 10.
What I want to do is try out the different MYS builds on domoticz ie MQTT and SERIAL as well as ethernet which I am currently running. However I'm not sure how to stop the current MYS service and completely clean up the current build to start from scratch... I have tried just re entering the ./configure commands then 'make' but this does not seem to work.
Many thanks,
Matt -

@Grubstake: Thanks. I have tried to follow "NRF24L01+ Radio" pin out connection. I have double / triple check my wiring is correct. But I still get the same fail message in mysgw debug mode:

Have set up the -d parameter in mysgw.servie and am waiting for it to fall over again.
If I catch it I will post syslog.
Thanks,
