In AP mode, you need to have your laptop or computer connect to the AP name that OpenSprinkler creates (the OS_xxxxxx SSID). Then once connected, open a browser and type in: http://192.168.4.1/update
That’s what I did but the webserver responds “page not found”. The only page I can navigate to is the root where I may choose which wifi network to connect to.
To enter bootloading mode, the correct procedure is as follows:
– remove all power from OpenSprinkler (i.e. remove orange terminal block, and unplug USB).
AHA! I didn’t remove AC power. I’ll try that tomorrow as neither OTA option works.
Thanks
