Meteobridge NanoSD endlessly resetting
« on: November 29, 2021, 12:25:24 PM »
Hi,

That's the problem in a nutshell. Looks a lot like it boots to the point where it's trying to access the Internet and Meteobridge, fails, restarts....repeat.

I think the original cause was a brief interruption to power, causing a WiFi repeater to restart and possibly change channel.

In the past when this happens, I've been able to access the in-built WiFi hotspot, log in and change stuff. Usually a save+reboot is all it takes.

Right now, it never seems to get to the point where it brings up that hotspot.

I have tried:

Interrupting the boot by pressing the blue button on the logger. The LED changes to very rapid flashing if I do that - but no WiFi hotspot advertised. Further button presses DO NOT result in the LED reverting to a slow flash - so the various reset options aren't available either.

Powering off and on again - on restart the old pattern kicks in.

So I could do with some ideas about bootstrapping this thing into a stable condition, where I might reconnect it to my WiFi.

The set up:
NanoSD 2gigabyte.
Davis VantagePro console
Davis mains power supply plus console batteries for backup

Weather nets connected (on a good day): Wunderground and UK Met Office

Regards,

Andy

Would appear a weak internet connection?
This WiFi repeater sounds like it needs checking out?
How far is the NanoSD from this Repeater? How far is the Repeater from the main router?
Are you able to move the NanoSD closer to the main WiFi?
What is the color of the NanoSD wire strap, Black or Red

Hi Matt. The wireless repeater is doing a pretty good job for about a half dozen other devices. The internet connection downloads at around 100mb/s. The Nano is about 5 metres from it, line of sight. Thatís not to say that it gets a brilliant signal, because itís wall mounted. I might try and check that out, if I can coax it out of its loop. The strap is red.

Red Strap? Ok what is the capacity of the power pack? Original Davis or have you upgraded this already?

Fixed - for now.

I tried the power-on-off-on sequence in the thread above, in case the PSU in underpowered. Boot sequence preceded as normal but this time it advertised its internal WIFi hotspot. I connected and checked networking. It said it had successfully connected to the Internet, and the LED went solid. Iím tempted to think thereís at least a couple of issues:

- Nano not handling auto selection of WiFi very well, and Ďmissingí the allocated channel on boot (Iíve made channel selection static on the repeater at 2.4GHz)

- some challenges with the internal hotspot not being offered in parallel with using the radio to connect to the local network, which might I suppose be related to power consumption.

Iíll order a bigger PSU, and hopefully thatíll steady the ship.

Thanks for the help!
