Hi
I have three airrohr sensors that have been used (months ago) by some colleagues and students.
I can connect with all of them to their local Wifi access point, but with only one I’m able to access the config page on 192.168.4.1/config and connect it to my Wifi network.
With two sensors the config page doesn’t load, although I’m connected to it’s network.
Tested on several devices (phone, laptop).
Any idea what could be the problem and how to solve this?
Kind Regards,
Gwen
Hello @Gwen, the page http://192.168.4.1/ is only reachable if you are connected to the sensor wifi hotspot. After configuring the sensor with the wifi credentials of your home network you need to look for the local IP address that the sensor got in your network. Normally there should be a page on your router that is showing all connected devices with their corresponding IP address.
Hello @ricki-z. I know it’s only reachable if connected to the wifi hotspot. As mentioned, with two of my sensors I’m unable to access the config page while connected to the wifi hotspot. The page just keeps loading and I’m sure I’m connected to the sensor. I’ve tested this on several devices, all with the same result.
Try Erase Flash and Upload firmware again

Wifi Password: airrohrcfg
Nice feature “Discovery” sensors
Hi @fredvduin
I also tried that, but with no result.
On the website the only tool that runs on my Windows machine is v0.3.2.
I don’t find a v0.3.3 for Windows and the v0.3.4 Beta gives an error while starting.
I found this Github where there should be a flashing tool which can implement the Wifi credentials at the same time, so you could bypass the config page.
Unfortunately I have no clue with which version of the flashing tool this is possible.
The sceenshot shows vervion 0.3.2 on an Apple computer.
I only have Windows machines at my disposal, no Ubuntu or Apple.
My computer is a windows 10 computer and I use AMD64 V0.3.2 (picture)
Give this tool an error? or can you not access the NodeMCU.
You need a driver?
Ok, so v0.3.2 is the one to use, thanks.
After several tries I found the problem.
Our access points are suppressing any local Wifi network that appears.
So my phone couldn’t hold a stable connection to the sensor long enough for the config page to load.
Tried at another location and I was able to configure the sensor.
