I'm installing a NANO SD in my VantagePro2 station for the first time. The components are:
- Meteobridge NANO SD (red strap), with 125 MB total RAM (60 MB free; 51% used)
- storage WD SLC, 7.3 GB total, 7.2 GB free (1% used)
- SW Version Meteobridge 6.1 (Jan 27 2025, build 5033), FW 1.4
- web browser Firefox 135.0 in Troubleshoot Mode (all add-ons and extensions disabled)
The problem is that when I make a change to the Network or System configuration and reboot (using "Save and Apply and Reboot" or "Reboot" buttons on those pages), the system freezes solid and I have to power cycle the station to get any response at all from the NANO SD. When it freezes, the connection to my web browser is dropped, pings to the NANO SD's IP address get no response, the red LED is solid on (as if it were connected to the internet), and the reset button does nothing,
After the power cycle, any configuration changes I had saved _are_ applied and effective, so I _can_ change my configuration, but only by doing many power cycle restarts.
Any ideas what might be causing this problem?

Re: NANO SD freezes on reboot, requiring power cycle
Ok so installed in and older VP2 console that had been running for some time?
If so are you still using the old Davis power supply? If that is the case then power supply and especially for the red strap needs to be beefed up to at least 1A or better.

Re: NANO SD freezes on reboot, requiring power cycle
Yes, it's an older VP2 console that has been running for 8+ years with Meteobridge hosted on an external TP-Link unit, and it has been using the original, Davis power supply for the console (plus a separate supply for the TP-Link).
I will get a higher amperage 5V supply, install it, and report back.

Re: NANO SD freezes on reboot, requiring power cycle
Unfortunately, using a new power supply did not solve the problem - or if it did, it introduced a new one. I tried two, different 5V 1.0A power supplies and a brand new, 5V 2.0A power supply. The NANO SD will now occasionally boot up and connect to the Internet, but stays running only for a few hours before dropping the connection and freezing (no response when pushing the blue button). Oddly, it appears that if I power off the NANO SD and weather station for 4-12 hours and then restart them, they will sometimes boot correctly and connect to the Internet and send weather data. But only for a few hours before freezing up again. So...
I have reverted to using my TP-Link MR3020 v1.9 with a USB connection to my Davis VantagePro2 through a Belkin USB 2.0 F4U021 hub, and am "back on the air" sending weather data to Weather Underground and NOAA CWOP.
BUT! I would still very much like to use the NANO SD and eliminate the tangle of hardware and USB and Ethernet cables, so if you have any further ideas please let me know.

Re: NANO SD freezes on reboot, requiring power cycle
What is Nano to your router WiFi connection like?
Re: NANO SD freezes on reboot, requiring power cycle
The NANO reports a 94% WiFi connection to the router (it is located about 20cm from the router).
When I reconnected the NANO just now (with the 5V 2A power supply) it booted and reported its assigned IP address (192.168.3.31) by flash codes after a single press of the blue button. However it did not respond to an http request at that address. By connecting to its "meteobridge_XXXX" diagnostic WiFi, the NANO displayed its Network webpage (see attached screenshot) which said that connectivity was fine and I should Save,Apply&Reboot.
After doing that the NANO froze and would not even display its IP address in response to a single press of the blue button, much less respond to http or ping requests.
I then power-cycled the station and NANO by disconnecting and reconnecting the batteries and power adapter, but the NANO remained frozen.

Re: NANO SD freezes on reboot, requiring power cycle
What is the other SSID #1 @ 10%? Would that be interfering? Did you try the SSID #11?
Re: NANO SD freezes on reboot, requiring power cycle
The other SSID at 10% is a WiFi-connected doorbell camera. I don't imagine it would interfere with the NANO connecting to the router, considering how much stronger the router's signal is due to its being only 15cm away from the NANO.
Happily, though, I can now report a bit of success.
After posting my last entry, I noticed that the console's firmware was at rev. 3.15, where the current version is rev. 3.88. Updating a VantagePro2's firmware is not a simple process at all, which explains why I hadn't done so earlier. To get the latest firmware I had to create an account on Davis Instruments' "WeatherLink.com" site. But by reinstalling the original Data Logger in the console and connecting its USB cable to my laptop I was able to complete the update.
Having updated the firmware I restarted the console without either the NANO or the DataLogger+MR3020. I then used the console setup mode (hold DONE button; press - (minus) button) to verify that all the settings were correct (they were). In doing that setup, I noticed that the NANO was sometimes leaving the console in setup mode (with just "Receiving" showing) without displaying any data. After exiting the Setup screens (press-and-hold DONE), I accessed the console's Statistical Diagnostic Screen (hold TEMP; press HUM) to verify that it was receiving data correctly. It was - with a 94% rate of good packets, a background noise level at 15, and console batteries at 4.42V.
I then reinstalled and started the DataLogger+MR3020. It connected and uploaded data flawlessly, and I was able to access it at its assigned IP address (192.168.3.21). So it was time to re-try the NANO.
I powered down everything, removed the Data Logger, reinstalled the NANO, and restarted the system. The NANO completed its startup and showed a solid red LED fairly quickly. The console display was stuck in "Receiving...." mode, though, By pressing and holding the DONE button I was able to exit that Setup mode and to see live data on the console display. And then by entering the console's Statistical Diagnostic Screen (hold TEMP; press HUM) I could verify that it was receiving data from the sensors correctly. Interestingly, that screen showed that the console battery voltage was significantly lower (4.11V) with the NANO installed than when I was using the Data Logger and external TP-Link MR3020.
Initially, I couldn't connect to the NANO through its assigned IP address (192.168.3.31), but by going through its "meteobridge_XXXX" diagnostic WiFi I was able to see its Network webpage and press the Save&Apply&Reboot button on that screen. The NANO rebooted, and again fairly quickly showed its solid red LED. I was then able to successfully connect to its webpage at its assigned IP address.
So far the NANO has been successfully uploading data to Weather Underground and CWOP for nearly two hours. I plan to let it run overnight and see if it remains stable.
The bottom line is that I don't really know what I did that fixed the problem of the NANO freezing and being unresponsive.
- The console was receiving packets of data successfully, so I don't think that was the issue.
- Using the console DONE button to force exit Setup mode when the display was stuck on "Receiving" helped verify that the console was operating correctly.
- Using a 2A power supply might have been the solution, and if I have the time and inclination I'll see if reverting to my 1A and 0.3A supplies causes the problem to recur.
- Upgrading the firmware might have contributed to solving the problem.
For now, I'm going to leave it all alone and hope that it runs smoothly the same way the TP-Link MR3020 did for so many years.
If you have ideas that you'd like me to try, to help narrow down the root cause and solution of the problem I was having, I'm certainly happy to help.
And if it was the bigger power supply, then other readers might like to know that the 5V 2A I finally got was a "Max LLTo 5V DC 2.0A Wall Adapter AC Power Supply 5V DC 2A 3.5mm/1.35mm Class 2 Transformer" (Brand YaizK, Model Number MT-523, Manufacturer Maxinbuy).

Re: NANO SD freezes on reboot, requiring power cycle
This is what the Nano AP allows upon a reboot and then closes down after a set time for security purposes.....Initially, I couldn't connect to the NANO through its assigned IP address (192.168.3.31), but by going through its "meteobridge_XXXX" diagnostic WiFi I was able to see its Network webpage and press the Save&Apply&Reboot button on that screen. The NANO rebooted, and again fairly quickly showed its solid red LED. I was then able to successfully connect to its webpage at its assigned IP address...
Can not say I have encountered FW 3.15 with a Nano, Envoy FW 1.90, FW 3.8 and Vue Fw 3.00 have not had any issues.
The red strap Nano definatley requires the extra power as was released April 20,2019. High power WiFi like the red strap Nano and being so close to the router (15cm) could also be contributing to reception anomalies?
Meteobridge NANO: adds TX power boost mode for the new batch of NANOs (left picture, with a red strap instead of a black strap). This option makes use of the better RF power emission of the new batch of VoCore2 modules. Please be aware that this mode draws so much power that the console needs support by additional batteries or (better) a more juicy power supply (minimum 500 mA). The standard 300 mA power supply of the Davis console cannot feed this mode, voltage will plump on WiFi operation and make the NANO reboot. Please use this mode only, when you experience WiFi reach problems. If your WiFi operation is fine, don't mess with this mode. Black strap NANOs don't have this option.
Re: NANO SD freezes on reboot, requiring power cycle
Well, the brief success proved to be temporary. The NANO continues to freeze up on most reboots, and to only remain online for a short while if it does successfully connect.
I have tried all of the following, without success.
- renaming the WiFi SSIDs to unique names
- moving the console and NANO farther away from the router
- connecting to a different WiFi access point (on the same 192.168.3.* network)
Nothing has resulted in the NANO staying connected for more than a few hours.
I have reverted to using my Meteobridge WR3020 to connect my weather station to the Internet.

Re: NANO SD freezes on reboot, requiring power cycle
This looks very much like a power issue. Please add batteries in the console as well to help out with power demand spikes.
