@pepson only one word. Try. Really, you are lost in 1 cm of water. Try. And if it doesn't work, open your topic, showing exactly your sketches and what have you done.

Hi to all,
tonight I made update from 2.2.0 RC2 to 2.2.0 (stable) on my Raspberry PI3.
It is a live system (my heater control).

By the way the update is very simple.

First of all, backup or better CLONE your PI.

1 - Disable the daemon with

sudo systemctl stop mysgw.service && sudo systemctl disable mysgw.service

2 - Make a copy of the MySensors folder ( I made a copy with the name of version coming, so...)

cp -r MySensors MySensorsX.X.X(rc2)/

(the slash at the end means "It's a folder!"

3 - Remove the MySensors folder

sudo rm -r MySensors

4 - Git the "new" MySensors folder && configure it as usual. Remember to activate the daemon and see on Domoticz (for example) the gateway with new version

It seems that moving to last channel all nodes and gateways solved my trouble.

In this moment wifi is under heavy load (upload several video from several phones and tablet) and traffic leds never light the infamous red... neither nodes lost their gateway

@lassivv said in Multi Node project (MySensors noob) =RASPBERRY GATEWAY PROBLEM=:

Thx for info @sineverba but not help anything, same error message still.

I try with his kind configure:

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

Get this error back

mysgw: Starting gateway...
mysgw: Protocol version - 2.1.1
mysgw: MCO:BGN:INIT GW,CP=RNNG--Q,VER=2.1.1

Try the DEVELOPMENT branch, not the master.

I had my head broken on this with PI rev2.

How I get all working?

First of all, I did try on another raspbian the lib TMR20 and his "gettingstarted".

If all work with there, simpler at beginning than mysensors, I re-flashed a raspbian and:

1. Setup with raspi-config the SPI
2. Changed password to pi user
3. Installed git
4. sudo apt-get update (not upgrade, for info)
5. gitted from DEVELOPMENT branch
6. ./configured

and boom! All work.

After, I use rpi-clone and I did other tweaks on my distro (timezone, ssh, cron for backup, etc etc etc etc)

@pepson Last time. Please.
REMOVE
WHITELISTING
FROM
YOUR
SKETCH

Clear EEPROM and paste here output of debug. No other.

@pepson You use RFM69(H/W/HW). So I. My hint is remain with 2.2.0. I got so many issues with 2.3.0 and RFM that I reverted to 2.2.0 in 1 minute.

HMAC is not LAN MAC, is HMAC got from MYsensors gateway. Same for other 2 keyes.

I think that in long explain on my guide you have all info to get your keyes. I follow my same guide everytime I need to reinstall mysensors / domoticz / an entire PI. It is fully tested

@sundberg84 said in Can please someone check if my schema for RFM69 is right?:

@sineverba - 1 rule of debugging, remove as much as possible.
Can you try to use a 3.3v MCU directly with your breakout board? That way you can eliminate that the problem might be level shifting and work down the wiring to a minimum?

sure golden rule.
It works. Now it works. Directly on a 3v3 mini. Removed all level shifter. Now it works.
Thank you for the support!

@mfalkvidd I did introduce both on "difficult" node and after 24h NO NACK anymore.... Thank you very much!

@mfalkvidd For email probably solved. I re-saved my option and now seems working.

Thank you for the link. Sorry, I did not understand... I did see the link. Do I need to set both:

#define MY_PARENT_NODE_ID 0
#define MY_PARENT_NODE_IS_STATIC

Or only the second one (MY_PARENT_NODE_IS_STATIC) ? 'Cause I see for first one (MY_PARENT_NODE_ID ) default is AUTO, but I know that gateway is 0.

Thank you very much

Hi to all!
Want to share one of my project.

https://www.openhardware.io/view/544/Arduino-Atmega-Bootloader-Uploader

This is an Arduino shield to burn bootloader to the 3 different elements of family: an Atmega328, a Pro Mini and finally a Nano.

It is fully tested and working. I'm very happy with this for burn Optiboot on the nodes of my house.

I hope it will help someone.

Have a good day!

@neverdie Limited 50mm x 50mm at 5$, 100x100 15$. So, for small pcb price is same. For bigger, price is insane bytheway including DHL ship. From China to Italy, 3 days. Fantastic!

Happy Xmas to all forum users!
I need your help to focus and solve my troubles about NRF24, signing and Arduinos (UNO and nanos).

Previously I did start another discussion about this, opening a new one 'cause I did collect other infos and I would restart the discussion from zero.

Preamble > My environment

** Controller + Gateway **
Domoticz as controller on a Raspberry PI2 + Arduino UNO as gateway + NRF24L01+ PA/LNA. Antenna is powered from a socket getting 5V from PI Gpio and converted to 3V3. PI itself is powered with a charger 5V / 2A. UNO has write in EEPROM a fixed software serial from the security personalizer sketch and shares the same AES KEY for all nodes.

Current image of setup:

** Nodes **
I have 4 nodes with SI7021, custom PCBs, battery powered without boosters. NO signing, no security. They works perfectly.

Software: they have a software serial and share the same AES KEY with all other nodes.

3 of them have NRF24 black, I think counterfeit, but with 47uF caps on 3v3 and gnd. 1 of them has another type of NRF24, "red aliexpress version", with 47uF caps like others.

This is the "red" version:

Heater commander relay node
As name says, it's a node with a SI7021 + relay (based on secture actuator) that poweron the heater. It is on a custom PCB.

Software: has a software serial and share the same AES KEY with all other nodes.

You can see DOUBLE caps on it. Cap on the antenna + caps on the PCB (47uF + 0.1uF). Powered from a 5V / 2A Samsung charger (you can see the AMS converting the 5V to 3v3 and TPs, voltage are perfect) it works perfectly with UNO gateway.

That antenna was for testing solder, before mount on the wall. Now it has this kind of antenna:

It has security and whitelisting. Only because I don't want that another familty with mysensors could poweron my heater .

The big troubles

1 - If I swap the Antennas (BLACK LNA on relay node and GREEN on the gateway), security doesn't work. Period. Node relay wait for infinite for the nonce from gateway. I have 2x green and 4x black. I did try ALL antenna in every combination. No possibility to work.

The log is:

19544 Nonce requested from 0. Waiting...
24549 Timeout waiting for nonce!

2 - Sketch for Relay is a bit "fat". Uses 85% of memory. Cannot "put to diet". If I enable DEBUG + DEBUG SIGNING, it wait for infinite for

2134 Waiting for GW to send signing preferences...

The issues goes away when I comment both DEBUG or only the DEBUG_SIGNING. So, for debugging, need to remove the library for SI7021 and it's functions. Not very handly.

3 - Yesterday I did change the UNO with a NANO (on the gateway). Used same antenna and same power shield (5V from PI > 3v3 to antenna). Security signing stop working. After some restart of relay secure node, got the signing working. Of course, I did personalized with same serial software of the UNO and the AES KEY. From an hardware view, I did "swap" an ATMEGA328 with another with same, same, same configuration. No reason to break the environment.

For the moment (12h) all works, with the NANO. I cannot explain reason for relay node to make about 30/40 reset before re-start.

So, now my questions.

1. This is the GATEWAY UNO/NANO sketch. Based on the (looooong) preamble, is it right?

TL;DR:

• 1 gateway, software signing + software serial + aes key
• 4 temperature nodes without security
• 1 relay node with security

}

2 - This is the RELAY secure sketch, reporting the temp and relay state. It is a bit fat, use 85% of resource and cannot enable DEBUG_SIGNING without removing the SI7021 library. Is it possible to put to diet?

Thank you and again Merry Xmas!

Hi,
the title say all...
I have fun designing PCB for nodes. But, as title, do I need to implement the IRQ for them?

And, if yes, for the ATMEGA328 and NRF24 radio, what PIN are available for it? 'Cause, for example, I have a node very populated (interrupt, reset, tx leds, 2 sensors, 1 relay, etc etc) so many Atmega PINs are not available.

Thank you very much!

@zboblamont ok. I did not know cause I have a PI1. Btw, what about serial port name and out of the box working? Or need some edit on PI config?

Edit: I did read your answer late

@Boots33

Never seen the request function.
You are hero-member for a reason...
Thank you very much!

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

@sineverba

@sineverba said in Building a Raspberry Pi Gateway:

Going crazy here.
I did get success with MySensors and first Arduino node on a fresh Raspbian (last image) and branch development. All ok!

Now I want re-do on other SD (same Pi, same WIring, same Radio). I did put "old" sd on a secure location and re-start from scratch.

I did compile with:

./configure --my-transport=nrf24 --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyUSB020

and answer is:

[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.

Make ends with no error.

The debug

sudo ./bin/mysgw –d

locks here:

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

And no other lines.

I Repeat, same PI, same Radio, same wiring. If I try other SD, all goes ok and I can use it on domoticz.

Thank you

OK, re-re-done on fresh install and all went ok.

I think that problem was when I deleted the PI default user and created another one.

I did follow the gordon guide: https://gordonlesti.com/change-default-users-on-raspberry-pi/

Probably a permission issues changing or not changing root?

Thank you

@mfalkvidd yes, I'm using node 2 and mysensor 1 gateway.

Unfortunately I don't get on work 2.0 gateway.....

Next week I will restart with a fresh Raspbian, maybe I will solve my initial issues...

Thank you very much!

you have probably forgotten to run sudo make install. Read the instructions again, and follow them this time

In my case I did need simply to restart. I did "make install" but I did need to restart
