💬 Building a Raspberry Pi Gateway

@sineverba said in 💬 Building a Raspberry Pi Gateway:

I have a couple of nodes + PI working without issues from a couple of days.
Now, I would add encryption / signing / security etc to protect traffic between Arduinos and PI.
Could you please help me posting right configuration to add to the

./configure

command?

Thank you very much!

Sorry..... I would UP! this :)

[Anticimex]

@sineverba is there not a --help argument to get a list of settings?

[sineverba]

@Anticimex sure... Bit I did read also the guide and .... I did noto understand very well whats I need to activate (if need) on gateway and on Arduinos to block, for example, the persone that live on third floor to play with my heater ..... :-) thank you in advance

PS security only software, no other hardware implied / want use

Thank you!

[Anticimex]

@sineverba I am not sure I understand what you want. You want to enable signing? There is extensive documentation on how to enable that. As for what to pass to the configure command on a rPi I am unsure of the exact naming but I am pretty sure the names are very similar to the #define:s the signing documentation describes.

[sineverba]

@Anticimex Yes, the doc is ... maybe ... too extensive :)

By the way, I would signing. So I need to do on both? Gateway/Raspberry and Arduino?

Thank you

[Anticimex]

@sineverba I am not sure I understand how it can be too excessive? It sounds like it is inadequate since you still have questions. :)
Of course you have to enable signing on both node and gateway. You also need to personalize the services with a hmac key. This is described. Please read the docs carefully. And if they are unclear, please provide a link to the documentation you have read, so I can verify you read the correct one.

[sineverba]

@Anticimex
I'm talking about this: https://www.mysensors.org/about/signing

Seems to me that probably need to be more clear your hint: you have to enable signing on both node and gateway.

I hope that soon I will can test on my network :)

Thank you for the moment :)

[Anticimex]

@sineverba yes, well that is for the official release so so far so good. I assume you also run the official version of the library and not the beta version, right?
For details on rPi configuration, perhaps @marceloaqno can provide some assistance but you will find all information needed on that page for configuring signing on your nodes.

[sineverba]

@Anticimex On Raspberry PI V1 I can work only with branch development. With master the radio / serial doesn't work

[Anticimex]

@sineverba then please use this documentation instead.

[sineverba]

@Anticimex thank you but... it is not the same?

[Anticimex]

@sineverba no, it isn't. There are newer features on beta branch. A third simplified option for signing exist (and if you have a hard time figuring out signing I highly recommend you use it).

Raspberry PI V1 Model B (2 USB ports, no wifi, 26 GPIO).

RASPBIAN JESSIE LITE v 2017-04-10-raspbian-jessie-lite.

Some day ago I did compile the gateway only with development branch, using this:

./configure --my-transport=nrf24 --my-rf24-irq-pin=15 --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyUSB020

And all works fantastic.

Today I did try a new fresh installation for a friend, same PI, and same commands and routine from zero:

1. Logged with PI
2. Changed Password
3. Activate SSH
4. Activate SPI
5. Expand Filesystem
6. Changed timezone

launched

./configure --my-transport=nrf24 --my-rf24-irq-pin=15 --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyUSB020

No error on output, rebooted many times, gateways locked. See the screen:

With current setup (that works perfect), if I reconfigure to use Led TX/RX/Err, I get same lock.

I have SD and a copy of it, but I would setup another one from zero.... and I cannot.

Thank you

[sineverba]

I don't want give up!

I did download last RASPBIAN version (2017-06-21).
Gitted from development branch...

My question is.... is it a problem of my PI? Too old? Need to buy the V3?

I don't understand why some time ./configure works (and entire system with domoticz works without problem!!!) and other time no!

Hi to all!
I did another test, on a new SD with Raspbian Lite 2017-06-21.

It doesn't work. Hangs on protocol version.

But... I did note this, after ./configure

Master branch

I'm going crazy :(

Try DIETPI instead of raspian and see if it changes

[sineverba]

@gohan
I can and I will try, of sure. But, why do you think that something will change? My hardware is too old?

[skywatch]

Can you look and see what power supply you are using and also tell us what you have connected to the pi?
Do you have a volt meter and know how to use it?

[sineverba]

@skywatch
For a moment, I did hope that your was final solution.

By the way, I have HDMI attached (but TV is off) and a hub usb (with nothing attached).

I did try 7 sd cards.

I did try also Samsung charger (ETA U90EWE) and a powerbank, both 5v/2a

I have a cheap multimeter and I have basic knolewdge. What do you want I measure?

The radio is firmed soldered on an header array and linked with jumpers:

No caps 'cause the nodes and gw can transmit without problem on over 15 meters on my home :)

Exact configuration with a 7-days-old installation works very well. If I try to replicate, with every combination (last raspi/previous raspi/master/development) sometimes works, I re-flash and doesn't work anymore.

I'm not crazy, I would to be sure that in every moment I can replicate totally the configuration from scratch and... I want understand whats the problem!

PS The config that works very well, If I try to reconfigure to use the LEDS, after configure hangs on same, same step of debug. Luckily, I use rpi-clone before every single edit on my so-precious configuration.

PPS If someone wants, I could torrent my SD configured.... :(

[skywatch]

OK! - Now I am not saying I have the solution to your problem, but I think it is worth ruling out a few things.

If nothing is attached to the USB hub, disconnect it.
With your voltmeter set to DC Volts, measure between TP1 and TP2 on the pi. You should see 5V DC. Up to about 5.5V is OK, but less than 4.8V can affect some things. Many time I have seen power issues be the problem.

Why not wire the NRF24L01 direct to the pi?

If all is well, then seems it is software problem after all ;)
