Debug the Wifi Gateway ?

kr0815 last edited by

I built the dev version of the Wifi Gateway.
It´s running, but after several hours, it stops

I´m connected to it through my FHEM Controller and with a Putty Telnet session

Sometimes, it doesn´t fetch wireless messages from the sensors
Sometimes, it´s inaccessible from the controller / telnet
Sometimes it happens after startup, sometimes after many hours

I already tried with different power sources, capacitors,...
I also swapped the NRF24L01 to a total different one ( with / without external antenna)

Is there any possibilty for better debug output ?
By telnet, it only shows my the received / sent commands ?

Hi OSD, thanks for your input. Those are the 4 relays on IO-MCU. I buzzed out the circuit and found that I had an open circuit on the 12v line to the relays. Furthermore 2 of the relays indicator LEDs were illuminating, 2 were not. I suspect, when I first juiced up the circuit on this MCU, the 2 relays fired, but I'd made the trace too thin for the required current. I wired up some jumper wire on the reverse of the PCB and the 2 relays started working. The 2 that remain inoperable? https://forum.arduino.cc/t/using-pins-a6-a7-on-pro-mini-compatible/118050 A6 and A7 can only be analogue inputs, cannot be digitally written to..... - so this part of my PCB is now redundant. However, all in all, some good fault finding, found the two issues, and I'm now going away to re-think my PCB trace widths and reading the datasheets more accurately Thanks

Hi all, Should anyone face the same problem, I found the root cause: brownout threshold. I burned a new bootloader (Optiboot 8.0) without such trigger and the node has been working with used batteries (~2.7V) since May. Hope this helps.

Hm, maybe the problem is that your rPI has a short interruption in the WIFI connection, the MQTT TCP connection is interrupted and does not autostart again. Maybe there is something in the logs. Maybe you can find something about reconnects in one of these: journalctl --unit=systemd-networkd journalctl --unit=wpa_supplicant You could try to run wpa_cli in daemon mode to react to disconnects and connects. Create a script like this: #!/bin/bash case "$2" in CONNECTED) <your command to start the gateway>; ;; DISCONNECTED) <your command to stop the gateway>; ;; esac then, start wpa_cli in deamon mode: wpa_cli -a /path/to/your/script #use sudo if your gateway commands need sudo If that helps, you could create a service from this command. Regards, Edi
