I tried to update the Taranis firmware using the software supplied on the FrSky website. But it turns out it's version 2.1.6 - the same firmware as is already on the radio
So I went to the Open TX website for the most recent firmware, but according to the website OpenTX version 2.2 is only available after downloading the TX Companion in .exe format. So I downloaded the newest Open TX companion and installed it. But when I try to search for Open TX Companion updates, or Firmware updates I get an error message that says 'Unable to Check for Updates'.
How can I update the firmwares of the internal module, the Taranis' OpenTX firmware (version 2.2 apparently), or the X8R receiver firmware to the newest versions? Are the individual files available anywhere other than through the TX companion software (which can't search for updates) or the FrSky website (which seems to provide outdated files)?
