mysgw MQTT Issues

[xefil]

Hello to all,

I'm having issues with the only node in RF69 I've actually installed.
Switched to RPi and radio connected as MQTT server I'm getting this:

Is this !TSF causing me the issues not getting any informations from the node?
The node has worked well with RF68 on arduino (as gateway) before moving to RPi.
What could be the cause?

Thanks,

Simon

Why are you using version 2.2.1? What do you see on the node log?

I've noticed this now (remote) connected to the RPi. I can give a check on the logs of the node as soon I'm back.
About the version, which should I use? This is the first I've downloaded (months ago).
I've seen there is a v2.3.0-alpha. I could test it.

[gohan]

use the master branch that is 2.2, the 2.2.1 are 2.3 are alpha versions and still under development

Ok, this is something I can test right now!

Could it be a power issue? The radio is directly connected to 3.3V pin, without capacitor.

add capacitor and try again

Size? 100uF enough?

[gohan]

Yes, I use 10uF ceramic because of low ESR

Actually I've only electrolytic ones, I'll try meanwhile with that, thanks!

Hello!

Added capacitor, but it's still not working.
It has worked from some minutes but then no-more.

Seems the GW is not able to send out the answer.
BTW It gets every message from the node...

Ideas?

Thanks!

move node closer. You could also try swapping the 2 radio modules to see if the problem changes.

Strange is, the same radios had worked well until I've switched to RPi GW.
From the logs, correct me if I'm wrong, the issue seems to be on the gateway, not able to send the return/ack message:

!TSF:MSG:SEND,0-0-27-27,s=255,c=3,t=8,pt=1,l=1,sg=0,ft=0,st=NACK:0

The node is sending well!

TSF:MSG:SEND,27-27-255-255,s=255,c=3,t=7,pt=0,l=0,sg=0,ft=0,st=OK:

Or not??

I've added capacitors 100uf to both and, as well, added a copper coli antenna 868Mhz.
Now the GW is 10meters far away from the node. There is only one wall between.
I was testing to switch to RF69 radios which should be better if compared to nRF24L01+ in terms of range and walls.
This is not what expected...

I'll try to replace the radio on the GW side.

Any other suggestion is well appreciated!

Thanks, Simon

[gohan]

I forgot you had rfm69, so capacitor is not that important. Try to look at my rfm69 signal scanner and look for the code to print on debug the rssi of signal and output power and try to move around to see if you get any value change. I had problems with rpi3 gw using the alpha version, but on stable it works. You could also try to compile it as an ethernet gateway just to see if you get any changes. Can you also post the configure parameters you user?

Hello!
Which parameters?
compiling parameters of the GW?
I've configured it with:

./configure --my-transport=rfm69 --my-rfm69-frequency=868 --my-gateway=mqtt --my-controller-ip-address=192.168.1.50 --my-mqtt-publish-topic-prefix=mygateway1-out --my-mqtt-subscribe-topic-prefix=mygateway1-in --my-mqtt-client-id=raspberryRFM69

About the rfm69 signal scanner, should it run on the node or on the RPi?
(where to find it?)

Thanks @gohan :-)

Ok, then I need to upload it on the node (which is on a little wooden bird house) and go around with my laptop connected on it :-) Not a problem.
But would that report issues on the GW RPi as well? How?

Meanwhile I can try to compile the ethernet version to give it a try.

Thanks, Simon

Just a quick idea: are you powering the RFM69 from the Rpi?
I use a Rpi Zero W and when I powered my radio NRF24 from that it doesnt get enough juice even with caps.
I now use a bigger USB-wall wart and use AMS1117-3.3 to power the radio (PA-version) and added caps.

My two cents

Possible the problem is only sending and not receiving?
I've not tested the signal scanner right now.
I was hoping it's a power issue :'(

Hello @gohan ,

I was able to compile correctly the network IP mode. I had compiled it with the wrong transport.
BTW, now it initialized correctly, BUT same problems.
I've replaced the radio as well (only on the gateway).
Here the logs:

mysgw: TSF:CKU:OK,FCTRL

As you can see the SEND message fails.
I'll try now to move the node closer and then try the scanner.

Hope it helps :-(
