Hello again

I am having an issue with message signing. I have begun to expand my mysensors devices to include some actuators and sensors I want to secure. I have tried to get this to work, but keep hitting a wall.

Here;s my set up for my testing. My mega Ethernet gateway with software backed signing enabled, and my Uno set up as a mock relay actuator with software backed signing enabled. If I set up MY_SIGNING_SIMPLE_PASSWD "blahblahblah", everything works great. As soon as thats disabled...nothing wants to talk to each other.

How I have programmed the devices. On the gateway I ran the personalizer sketch and generated the HMAC and AES keys. I copied that info into the proper sections, disabled generate keys and enabled personalize soft. I then ran the personalizer on both the gateway and the node and received a "Succes" message.

This is my gateway sketch.

 * DESCRIPTION
 * The EthernetGateway sends data received from sensors to the ethernet link.
 * The gateway also accepts input on ethernet interface, which is then sent out to the radio network.
 *
 * The GW code is designed for Arduino 328p / 16MHz.  ATmega168 does not have enough memory to run this program.
 *
 * LED purposes:
 * - To use the feature, uncomment MY_DEFAULT_xxx_LED_PIN in the sketch below
 * - RX (green) - blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
 * - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
 * - ERR (red) - fast blink on error during transmission error or recieve crc error
 *
 * See http://www.mysensors.org/build/ethernet_gateway for wiring instructions.

All
A little while ago I had upgraded to MySensors 2.3.0 with horrible results....my 18 node network went kablooey. I couldn't get anything stable to save my own life. I was getting 30-90 minutes of runtime on the gateway before it was shutting down and going off line. I of course did this at the exact same time I was rebuilding my gateway, transitioning to the Mega 2560 from thr UNO 328 due to memory and lag issues. To top it all off I am running an NRF24 LNA/PNA radio at MAX because of distance and placement issues.

What I have found was needed to stabilize the gateway.....POWER POWER POWER! It became the Achilles heel of my project. I was initially feeding into the radio then sending power to the Mega via its VCC input (this was ok for the UNO). Voltage going over was good, current wasn't and the gateway would shutdown no matter what the radio power settings were of which radio chip I used. So I switched to a 12v 2.5A power supply and wyed it one connection to the radio board (which has its own voltage regulator) and the other to the Mega's DC jack. Second issue I noted was heat - the Mega runs hotter than the UNO did. I had 130 degrees Fahrenheit on the processor chip. I solved that with a heat sink I had from a raspberry pi and adding a small fan fed from the Mega's 5v pin placed at the back of the Mega. Since that, chip is a cool 80 degrees. I suspect since Im using the Ethernet shield that played a big role in the Mega heating up and the fan really helped.

The Fan is seen to the immediate left of the LAN jack.
The toggle switch serves 2 functions...when pushed to the right it resets the gateway, to the left enables inclusion mode. The three LEDs are TX/RX/ERR.

Hope this helps folks. I will add my wiring and code when I get a chance.

Heres the gateway mounted in my Ubuntu box, which runs my home media server and OpenHab.

Happy Building and THANK YOU to everyone who has posted ideas and code snipets that made this possible.

Morning all.
Ive just had to completely rebuild my openhab and mysensors set up. Im running OH 2.4 on a Raspberry Pi 3B+, with the MySensors 2.4 bindings. Gateway compiles and runs fine....butttt I acidentaly configured --my-leds-blinking-inverse. How do i unconfigure it.

Second led issue. The red error led is always lit, no blink, just steady burn. It is wired as noted in the guide.

Should i reneter the options and then remake the gate way? Im not sure how to go about this I was using arduinos before and there you just deleted the options from the sketch and reloaded it.

Thanks for the advice in advance

Hello again

I am having an issue with message signing. I have begun to expand my mysensors devices to include some actuators and sensors I want to secure. I have tried to get this to work, but keep hitting a wall.

Here;s my set up for my testing. My mega Ethernet gateway with software backed signing enabled, and my Uno set up as a mock relay actuator with software backed signing enabled. If I set up MY_SIGNING_SIMPLE_PASSWD "blahblahblah", everything works great. As soon as thats disabled...nothing wants to talk to each other.

How I have programmed the devices. On the gateway I ran the personalizer sketch and generated the HMAC and AES keys. I copied that info into the proper sections, disabled generate keys and enabled personalize soft. I then ran the personalizer on both the gateway and the node and received a "Succes" message.

This is my gateway sketch.

What am I missing here?

As promised this is my wiring and code, hope this help people out

First the wiring.

Radio - Mega Pin
+3V - NA
-3V - NA
CSN/CS(Yellow) - 6
CE(Orange) - 5
SCK(Green) - 14
MISO(White) - 15
MOSI(Blue) - 16
IRQ(Gray) - 2

Switch - Mega
Left - RESET
Right - 3 (inclusion Button)

LEDs - Mega
Red(Err) - 40
Orange(Rx) - 42
Green(Tx) - 44
All are grounded with 330 Ohm resistors.

And here is my Sketch. One thing I had done when I was just getting lots of shutdowns and errors was to wipe the board - I uploaded blink and left it alone for a minute and then reloaded the gateway with the updated libraries and (knocking on wood) it seems to be stable.

 * DESCRIPTION
 * The EthernetGateway sends data received from sensors to the ethernet link.
 * The gateway also accepts input on ethernet interface, which is then sent out to the radio network.
 *
 * The GW code is designed for Arduino 328p / 16MHz.  ATmega168 does not have enough memory to run this program.

 * LED purposes:
 * - To use the feature, uncomment MY_DEFAULT_xxx_LED_PIN in the sketch below
 * - RX (green) - blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
 * - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
 * - ERR (red) - fast blink on error during transmission error or recieve crc error

@scalz It was the big chip on the board heating up. I had thought that too so I swapped the mega out last night(had to wait until Amazon delivered it). It got warm (100ish Degrees) but not as hot as the other one did. But I tried to power the gateway as I had originally and the problems started right up again. So Im going with the issue was power related. Im going to keep the fan because a little extra cooling isn't going to hurt anything.

All
A little while ago I had upgraded to MySensors 2.3.0 with horrible results....my 18 node network went kablooey. I couldn't get anything stable to save my own life. I was getting 30-90 minutes of runtime on the gateway before it was shutting down and going off line. I of course did this at the exact same time I was rebuilding my gateway, transitioning to the Mega 2560 from thr UNO 328 due to memory and lag issues. To top it all off I am running an NRF24 LNA/PNA radio at MAX because of distance and placement issues.

What I have found was needed to stabilize the gateway.....POWER POWER POWER! It became the Achilles heel of my project. I was initially feeding into the radio then sending power to the Mega via its VCC input (this was ok for the UNO). Voltage going over was good, current wasn't and the gateway would shutdown no matter what the radio power settings were of which radio chip I used. So I switched to a 12v 2.5A power supply and wyed it one connection to the radio board (which has its own voltage regulator) and the other to the Mega's DC jack. Second issue I noted was heat - the Mega runs hotter than the UNO did. I had 130 degrees Fahrenheit on the processor chip. I solved that with a heat sink I had from a raspberry pi and adding a small fan fed from the Mega's 5v pin placed at the back of the Mega. Since that, chip is a cool 80 degrees. I suspect since Im using the Ethernet shield that played a big role in the Mega heating up and the fan really helped.

The Fan is seen to the immediate left of the LAN jack.
The toggle switch serves 2 functions...when pushed to the right it resets the gateway, to the left enables inclusion mode. The three LEDs are TX/RX/ERR.

Hope this helps folks. I will add my wiring and code when I get a chance.

Heres the gateway mounted in my Ubuntu box, which runs my home media server and OpenHab.

Happy Building and THANK YOU to everyone who has posted ideas and code snipets that made this possible.

I hadn't seen that, as it appears it was posted after I had written my post.
I had changed the CE/CSN pins based on the tutorial written on the Site and numerous other posters had states they had to make those changes to get the Mega and W5100 Shiled to work.

I will give this a try and see what happens.

Thanks you for the point in this directions.....Y'All rock

DB

Wow thats quite the project.....Im a pretty new guy here also. I tried something similar with my nano(and then uno) gateway and adding some sensors to it....I eventually abandoned it because it was just causing a log jam of data through the gateway and controller(I use OpenHAB), also if the sensor malfunctioned it took down the gateway on several occassions

My reccommendation is to set up a controller and gateway as standalone devices and then tie sensors and actuators in from there. Ive also found that it makes troubleshooting issues because the system is more modular.

Just my advice,, Wish you lots of luck and hope its as good and experience for you as its been for me.

I am in the process of moving my gateway over to an Arduino Mega 2560 R3.....presently it is running on an UNO R3 but that is my template device and I kinda want it back for that. Im using a W5100 Ethernet Shield, found here

My base gateway code comes from this post.

And my wiring is; (power is just off the Mega for testing only)
NRF - MEGA
Vcc - 3.3V
Gnd - Gnd
CE - 49 with change made in code
CSN - 53 with change made in code
SCK - 52
MOSI - 51
MISO - 50

 *******************************
 *
 * REVISION HISTORY
 * Version 1.0 - Henrik EKblad
 * Contribution by a-lurker and Anticimex,
 * Contribution by Norbert Truchsess <norbert.truchsess@t-online.de>
 * Contribution by Tomas Hozza <thozza@gmail.com>
 *
 *
 * DESCRIPTION
 * The EthernetGateway sends data received from sensors to the ethernet link.
 * The gateway also accepts input on ethernet interface, which is then sent out to the radio network.
 *
 * The GW code is designed for Arduino 328p / 16MHz.  ATmega168 does not have enough memory to run this program.
 *
 * LED purposes:
 * - To use the feature, uncomment MY_DEFAULT_xxx_LED_PIN in the sketch below
 * - RX (green) - blink fast on radio message received. In inclusion mode will blink fast only on presentation received
 * - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
 * - ERR (red) - fast blink on error during transmission error or receive crc error
 *
 * See http://www.mysensors.org/build/ethernet_gateway for wiring instructions.

But no matter what I do I get the following error.  Ive read through every post I can find here and nothing seems to get me going.

0 MCO:BGN:INIT GW,CP=RNNGA---,VER=2.3.0

Any ideas? If I load any other gateway sketch it fires up without a problem.

Thanks a bunch.

But Im still getting this error.

exit status 1
Error compiling for board Arduino/Genuino Uno.

Im at a total loss. The return_codes is located in a separate folder in the libraries file - SRC (which has the main sha204_library.h file), under the SRC folder is a folder titled "includes" which has the 'return_codes.h' file. Any attempt to place it in the #include decleration results in this error.
