<![CDATA[Multiple NRF24L01+ gateways]]>HI all!

I added a second gateway to my controller set-up.

It is working fine, but with one slight issue.

When I look under resources->gateways I can see the 2 gateways and select them to see details etc. All is as expected here.

When I look under resources->nodes however, I only see one gateway. I assume this is because they both get/have node EUI0?

Is there a way to display both GW in the 'nodes' page? If I add MY_NODE_ID to override the default in the GW sketch, will this also affect the "PARENT" id too?

So why do I see both GW in resources->gateways, but only one shows in resources->nodes? I can't figure out what is going on here......

So how does mycontroller differentiate between gateways if both are having node id 0?

Internally it keeps a unique id for each gateway. Quick view:

You have to maintain a unique node id inside a gateway only.
So each gateway can have the same node id.

@skywatch Sorry for the delayed response.

Me too! 😉

Well I have done more on this to see what might be happening and it seems that my last hope (that each gw needed it's own node id) was barking up the wrong tree.

So how does mycontroller differentiate between gateways if both are having node id 0?

I also removed that 3.3v 8MHz promini GW and replaced with a 5V one. Now both GW have the same serial speed (115200) in case that was an issue.

I need to reflash one GW and will make another soon so that both are identical as far as is possible.

We never stop learning (unless we choose not to and that would be an awful pity)!

It is odd. I could not guess the real issue.
Can you please change the serial driver from Auto to jSerialComm and check the status?

Earlier this week MyC was showing all nodes from one GW as down, the other GW was still working as was McA. I replugged the GW into the pi USB port and it all started working again.

Yesterday I noticed no automation and upon checking again had all nodes down (this time on both GW's). So I edited ALL GW configurations (as you advised above) and still nothing. After a few shutdown/poweron cycles it finally started working again - but only for half an hour when it all broke again.

From the below photo you can see that MyC sees the GW is 'UP' and running normally......

gateway.jpg

Then,clicking on the nodes info we see that all are down....

nodes.jpg

This is unexpected as MyC can see and report the messages from the nodes via the GW.

The log file is similar to the last one I sent you with a lot of garbage messages like this.....

log.jpg

So as far as I can see there is an issue, but not with the GW as I thought as it still works as far as MyC is seeing the data. So the question is what is going on here?

I am puzzled by this situation!

UPDATE - Even stranger now!!!!

So this morning all the nodes on GW were showing as 'down' with the GW showing up. Last seen on the nodes was 12 hours ago.
Just out of curiosity I tried sending a LED lights on and it worked! So did LED lights off and then on again! - Yet only those messages showed up for the node in sensors action and still the node shows as 'down' for 12 hours. I guess that this is due to one way communication of the lights messages.

NOw I notice that when a IR command is sent it is wotking as expected but no message shows up in 'sensors action' ????

Thanks for the help resolving this! 🙂

@skywatch Thanks for the logs. Can you edit and save again gateway2 and see the behavior?

I have done as you say. I'll keep an eye on it and see how things go. Thanks! 🙂

But just to be clear, GW2 is the MQTT GW for McAgent, the errors in the log were all GW5 related though?

On the node page gateway, details will be.

No - or at least not knowingly 😉

Yes there are errors - but for some reason I can't post the code in code tags.
