How to Update FrSky Receivers Firmware

Why would you need to update FrSky receivers firmware?  It’s easy to do that’s why.  Jk, I ran into an issue with the last batch of XSR receivers.  They were pre-flashed from the factory with version 170605 firmware.  Not sure why they did this because this version doesn’t work with the LUA script or telemetry.  You would get telemetry readings but the voltages were all off.  The LUA script either got readings or no readings but you can’t save any of the settings like PIDs or VTX channels.

Looks like FrSky knew they goofed up with this version firmware because they quickly updated it with version 170619.  This version works with the LUA script and correct readings on telemetry.  So if you are having issues with your LUA script not working (no readings or unable to save new settings) or you have wrong VBAT readings, it’s probably running firmware 170605.  Update the FrSky receivers firmware and it will fix the issue.  Here’s how you update the firmware.

If you found this post helpful, it would be super cool if you purchased the components from my store or purchase items from my Amazon links.  These posts are expensive and take a loooong time to make so the purchases make it possible for me to keep making them.  Thanks in advance, I greatly appreciate it 🙂
