[Feature Request] Provide Update Links to Older Firmware?

[ksquared83]

In the course of dealing with #316 I had to roll back to earlier firmware versions, but there doesn't seem to be any direct way to flash older updates directly from https://www.airgradient.com/documentation/firmwares/.

I understand that all old versions can be compiled from Github, but installing the entire Arduino IDE toolchain to compile existing older versions is a big lift (and I happen to lack sufficient local storage to install new tools). I ended up finding old firmwares here https://www.airgradient.com/documents/fw/new/combo/ and just modified the "Flash Now" link with Chrome's Developer Tools to try the old versions.

Since rolling back to older versions is a common pattern when issues are encountered, it might make sense to keep these directly accessible from the firmwares page.

If you are comfortable using the dev tools in your browser, then you can edit the manifest=... attribute of the "Flash Now" button on the firmware page to flash other versions of the firmware.

You should be able to change the 3-3-6 version number in the manifest attribute to any value listed here: https://www.airgradient.com/documents/fw/new/combo/

Then click the button to flash via the online flashing tool like normal. I've only personally tried this with 3-1-13, but it worked great for me.

It would be nice to be able to do this without modifying the source code of the page though.
