Hello. I am attempting to set up the PA-I (not the touch version) and the PurpleAir Classic devices purchased about a year ago. Both result in the same issues. Although the the ESP is hosting the wifi network at PurpleAir-**** and upon selecting the network, it does not allow you to connect. This has been tested on multiple clients, all with the same result. The serial output appears to be normal and I have attempted to re-flash the firmware, which changed nothing. What steps can I take to fix this?
Are you still having this issue? Often, multiple attempts in succession will allow you to connect. You may need to power cycle your device.
