Lastest FrSky Firmware Release Breaks Serial RX Connection
We like to update our components’ firmware right away to get all the latest errata fixes and features.
In this case, the latest FrSky R-XSR firmware release ( R-XSR_FPORT_FCC180228.frk ) broke the Serial RX connection.
We recommend that you use the ( R-XSRFCC171009.frk ) release; which we have found works as expected.
As a disclaimer, we do NOT test the firmware beyond our own usage model and subsequently do NOT test each errata fix or feature add.
Therefore, use this firmware at your own risk.
This post is simply a Heads Up ! that the latest release clearly breaks the Serial RX connection so don’t waste too much time debugging.
