Few days ago I noticed most of links from Google and this forum leading to sdk.hardwario.com are not working. Now I realized that you renamed libraries and functions from bc_ to twr_. So https://sdk.hardwario.com/bc__module__battery_8c_source.html#l00080 doesn’t work, but when I retype it to https://sdk.hardwario.com/twr__module__battery_8c_source.html#l00080, it works.
It would be really nice if you setup server side rewrites to do this permanent redirect for users. You won’t lose tons of indexed pages and users won’t be so upset like me, before I realized what’s going on (nobody really likes 404 errors, right)?
