I ordered a kit with NodeMCU and SDS011 and following the guide I was able to set it up successfully, it already appeared under my devices and on the map, with incoming data.
Then I decided I want to send data to a third party API, so I unplugged the sensor, waited for it to restart, and wanted to set up wifi connection + custom API, but ever since I am unable to even join the wifi network. It connects for a short while (I can see it on the router’s admin page), then disconnect. The sensor’s network in the meantime is always visible (airRohr-).
Are you sure you want to connect the right way. YOu should be able to access the sensor through the router on an adresse 192.168.1.<100 or something>. Check the DHCP client list of the router.
If you keep seeing the AirRohr-… network it means you are not connected to your router at all. And you have only 10 minutes to connect because of security reason. Please read the instructions attentively.
As I also have no idea what’s going wrong I tried debugging a bit. It would be most useful to see the logs, but I haven’t managed to make it work as the flashtool documentation seems a bit outdated (driver link for the NodeMCU is broken). Do you have any tips on debug tools?
It worked out, thanks for the responses. I checked the logs with Putty and it was unable to connect to the wifi. Interestingly, after a wifi network restart it worked again. ¯\(ツ)/¯
One more follow up question: what is the easiest way to change the sensor configuration (connect to a different wifi, send data to a different custom API, etc.)? Without having to disconnect and wait for it to forget the config
