I’m trying to upgrade to the latest version of OpenSprinkler version 2.1.9 rev3.
In this mode I navigate top the update url on the device, upload the latest os_219_3.bin file, specify the password and click submit.
The software is submitted to the device, I can tell it reboots as it looses the WIFI connection but it NEVER gets back online. I’ve waited hours for it to complete. The only way to get it back online again is to cut power but then it boots in the old version 2.1.7
I’ve tried this both with my old config and after a factory reset.
AP mode doesn’t work at all as the update url doesn’t exist.
I’ve followed the instructions herehere but I can’t get it into bootloader mode. B2 button just doesn’t react other than rebooting the device.
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
To enter bootloading mode, the correct procedure is as follows:
– remove all power from OpenSprinkler (i.e. remove orange terminal block, and unplug USB).
– press and hold B2, then plug the USB cable in. Then release the button. The LCD will remain off, indicating it’s in bootloading mode waiting for program to be uploaded.
