Gateway using mysensors 2.3.0.......

/**
* The MySensors Arduino library handles the wireless radio link and protocol
* between your home built sensors/actuators and HA controller of choice.
* The sensors forms a self healing radio network with optional repeaters. Each
* repeater and gateway builds a routing tables in EEPROM which keeps track of the
* network topology allowing messages to be routed to nodes.

* DESCRIPTION
* The ArduinoGateway prints data received from sensors on the serial link.
* The gateway accepts input on seral which will be sent out on radio network.
*
* The GW code is designed for Arduino Nano 328p / 16MHz
*
* Wire connections (OPTIONAL):
* - Inclusion button should be connected between digital pin 3 and GND
* - RX/TX/ERR leds need to be connected between +5V (anode) and digital pin 6/5/4 with resistor 270-330R in a series
*
* LEDs (OPTIONAL):
* - To use the feature, uncomment any of the MY_DEFAULT_xx_LED_PINs
* - 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

@skywatch

you are using a 3.3v promini as a GW.... 2 questions...

how do you get the data from the promini into the RPI, how is that wired since the promini does not have an USB port...
the GW sketch you posted is designed for an arduino nano 16Mhz, if you use a 3.3v promini it needs run at 8Mhz... Try to make this change in the GW sketch to hardcode the 8Mhz feature. It might be that the cpu freq in the if statement is not picked up bt the compiler, so try with the if statements removed.

#if F_CPU == 8000000L
#define MY_BAUD_RATE 38400

Can you try an arduino nano + NRF24L01 as gateway, and connect it to USB (if you have one lying around)

Just as background info, my 1st mycontroller setup was an RPI 2b with an arduino nano on usb that acted as a GW... had this setup for years and it worked flawless, other versions of the SW, but still....

@Tag

Thanks for the reply. In answer to your questions.....

The pro mini is connected via serial connection to the pi (tx/rx on pro mini to tx/rx on pi). I chose 3.3v pro mini as then there is no level shifter needed.
It is definitely being picked up by the compiler as the serial rate between the pi and promini works at 38400. If this were not picked up I would expect 115200. I don't have a nano anywhere, but could try a uno or mega.

I now am running on a 'Pi Hut' 5V 2A supply and have had 2 junk node id's already this morning (But this time both from the same node I think, so will look into that as well). I am also going to see what good power supplies RS Components has and probably add a mains filter as well.

Tag

Ah okay!,
Well, it might work this way, but sometime ago I ran into issues with serial comms where the TTL level between high and low was different between systems, and had to use a pull down resistor to fix this...

Another solution is to remove the arduino from the equation... it is possible to use plug the radio directly on the GPIO header of the RPI.. For a howto look here

Got this working for over a year now on and OPI zero and it works as expected.....

skywatch

@tag I originally had the nrf attached directly to the pi and moved to an arduino GW as I had issues with the directly connected setup (also I realised that HW signing is only supported for arduino GW and not for NRF attached directly to the pi).

However, I have discovered something.

I am testing it since yesterday lunchtime. At the momtent it looks good, but I have been at this point before.

Give me a few days to test and I will report back then.

I seem to have found the root cause of this, now working for 4 days with no corrupted data. But I have seen this overnight in the log, anything to worry about?

It is a holiday weekend here, but I will post the story of how I found and fixed the issue. You can all guess if you like. I bet nobody will get it!

Great news! :thumbs_up:

But I have seen this overnight in the log, anything to worry about?

How often are you seeing this log? If you see this error very frequently kindly report a bug/issue. I do not get any clue why failed to retrieve a node from the database. A particular message will be dropped(without any action) when you face this issue.

It is a holiday weekend here, but I will post the story of how I found and fixed the issue. You can all guess if you like. I bet nobody will get it!

Enjoy your holiday weekend! I am eager to see your fix

jkandasa

@skywatch Can you break the surprise?

skywatch

@jkandasa OK - it's a long story though......

So for the last 2 months after upgrading to mysensors 2.3.0 I get the library update pop-up with arduino IDE - It sometimes tells me to upgrade to a lower version of the library than I already have, so I figured it was a bit buggy.

Recently it was telling me I needed to upgrade to the latest mysensors 2.2.0 - But since I already had 2.3.0 installed I ignored it and carried on. After all, all the nodes reported as 2.3.0 and there was only 1 mysensors folder inside the libraries folder.

But when I went into the mysensors examples to clear eeprom, I found 2x mysensors options. They were different. I was baffled. I rechecked the libraries folder, only one mysensors folder. I checked app data, program files, temp files and everywhere I could think of. No other mysensors folders present.

After a lot of searching I found something interesting - In the arduino libraries folder there were a few 'arduino xxxxxx' folders (where xxxxxx was 6 seemingly random digits). Inside one of them were files relating to mysensors 2.1.1. - I deleted this folder and tested the IDE which compiled mysensors sketches with no issues.

With this rouge folder removed I decided to re-flashed the gateway and all nodes. This was the point that all the problems went away (and now even ack works properly)!

So it appears that this was the issue - it explains why the issue was only affecting me, but I still can't figure out what was happening fully as the nodes all reported as 2.3.0 and yet somehow having an older mysensors.h and mysensorscore.h inside a folder that wasn't mysensors in any way seemed to be causing the issue.

Still I found the problem and now have a stable system. It just goes to show that if you don't give up, eventualy you'll make progress.

So a big THANK YOU to you all for the help with this and sorry for taking your time on this one.

It's a learning curve for sure!

jkandasa

@skywatch Interesting story

So a big THANK YOU to you all for the help with this and sorry for taking your time on this one.

No worries at all. I have fixed couple of other issues(when working on this) and we have improved MyController quality further

skywatch

@jkandasa Thank you! - I have no idea what created those arduinoxxxxxx folders, there were 4 or 5 of them. A casual look and it's easy to think they are part of the internal arduino ide or something.

Still, at least I may make more progress now.

But not a time for relaxing, I still have FOTA, SWsinging, HWsigning and low power battery nodes to learn! - You have been warned! Hahahaha.....:)

jkandasa

@skywatch

You have been warned! Hahahaha.....:)

@jkandasa - I was about to mark this as solved, but this morning while I was asleep it did this to me....... MyC 1.4.0 snapshot installed......

jkandasa

@skywatch looks like some corruption in received data from your serial port.

skywatch

@jkandasa Today I noticed no data for 2 hours from any node.

I disconnected the pro mini from the pi, waited 20 seconds and then reconnected. The GW reconnected fine with MyC and all node data returned again.

So I guess we can be sure it is either the serial port on the pi locking up or the pro mini serial having an issue.

At least it is proven where the issue is, now to look into it some more. I will get around to trying the 5V pro mini as a GW (with level shifter for serial) just to see if that is the problem. I will also ask the question on the MyS site as well to see if anyone has similar problems.....

jkandasa

@skywatch well, at least we find the issue where it is.
If you have USBtoTTL you may use that one.
I used cheap Chinese USBtoTTL all the time works well.
I used this one from Aliexpress.

skywatch

@jkandasa Thanks for the reply.

I do wonder though that if the problem is with the GW serial port then it will be just as likely to fail connected to a serial to usb connection as well as when connected to a pi. Unless the pi is somehow upsetting the serial port on the pro mini in a way that the usb to ttl will not.

I did ask on MySensors forum about using 3.3v pro mini as GW and the problems I experience, but no replies yet.

I'll try and modify things for a 5V pro mini on serial in the next few days and if that doesn't solve the issues I will try the usb converter you suggested (I have one somewhere!)....

Thanks.

skywatch

@skywatch I couldn't find a usb converter so I ordered a couple just in case.

FWIW I also added a temperature controlled 20mm fan to aid the cooling of the pi. Even with the big heatsink posted earlier in this thread, you can see the difference when the fan is activated.

I only used 4 components to make a fan controller that works with a python script to control the speed according to cpu temperature - so virtually noiseless in most circumstances.

Oh, I may have some news about this issue tomorrow as well....... (Queue suspence music from 1950's horror/scifi movie).....

skywatch

@jkandasa

You will be happy to know that this issue is now SOLVED!

Since installing the latest SNAPSHOT 1.4.0, all the problems associated with this have gone away.

Phew, what a little sod this problem has been, but we never gave up and all is well now.

Big thanks!

jkandasa

@skywatch Great! nice to hear this.
You may disable gateway(after some days) raw message DEBUG to INFO, this log will keep growing.
