OLED display not update EKF


I used Pixhawk 2.1 with firmware 3.5 RC7. Although EKF bar full red (Mission Planner, test with compass near metal), but the OLED LCD status EKF always show is OK.

sorry cannot help …but where did get the oled …banggood or ebay link please…looks cool

That looks like the banggood link. But you can also get it on Aliexpress or any other source

These work with Pixhawk 1…

this one is out of stock on banggood and aliexpress is too slow to spain so I went for a color led one …seems to work too on pixhawk 2.1 … thanks again

Here’s the wiki page for the display including some links in case that’s helpful. http://ardupilot.org/copter/docs/common-display-onboard.html

Thanks for the report, I’ve confirmed this is a real issue and raised a to-do here: https://github.com/ArduPilot/ardupilot/issues/6352

My guess is that the “EKF:ok” is connected to the EKF failsafe which is probably not the correct behaviour because we don’t allow EKF failsafes to trigger while the vehicle is disarmed so it will always show “ok”.
