So .. I have project on my plate which is basically a firmware updater for a project based around the ESP8266 (see <a href="http:&#x2F;&#x2F;magicshifter.net&#x2F;" rel="nofollow">http:&#x2F;&#x2F;magicshifter.net&#x2F;</a> if you&#x27;re interested).<p>My question to anyone who knows the answer: would it be possible to write an app (in Linux of course) which access the &#x2F;dev&#x2F;tty.FORESP8266 and writes&#x2F;reads raw blocks, such that it could be bundled into AppImage and run on, basically, OSX and Windows as a Linux app - and still have the raw i&#x2F;o access it needs to perform a firmware update?<p>If so, I&#x27;m willing to expend the time to learn how to use it and build this app .. it seems to me to be a more interesting approach than using, for example, Qt to build a cross-platform serial i&#x2F;o app ..
