Solution -can't pass Compass calibration?

Post by Hubsan-Ailsa » Mon Jan 14, 2019 2:13 am

Having trouble getting through either compass calibration 1 or 2? Never fear, Back to Basics is here!

Cheesy intros aside- really, this tutorial is here to help you troubleshoot compass calibration. Let’s get started.

1) There is no prompting on the transmitter screen- it’s all black and the aircraft’s LEDs are going around in a circle! Help!

Answer: The transmitter and drone need to be re-bound to each other. Use the below link to rebind and you’ll find that everything works.

2) There is no prompting on the transmitter screen- it’s all black and the aircraft is beeping loudly, continuously and incessantly. The top of the screen reads “Check Gyro Sensor” and it never goes away! What’s going on?

Answer: You most likely have an H501SS. Check with the below video. If you have an SS, you need to reflash (redo) the Flight Control firmware (visit www.hubsan.com, “Support”, “Product Support” to get the firmware and instructions). If you have an S, try reflashing the Flight Control firmware as well- if it refuses to go through, please email service@hubsan.com and/or reach out to the Hubsan community online. You might have a hardware problem.

3) Okay. So everything’s showing up on the screen: telemetry, Calib. Compass 1 and the drone’s LEDs are flashing in a clockwise circle. But I can’t get the drone to get past Calib. Compass 1!

Answer: First, place the aircraft on a flat surface and let it stay there for 20 seconds. Then, calibrate. That should solve your problem. If it does not, power off the aircraft and change locations. Make sure you have no ferrous metals, electronics with strong magnets in them (like high quality speakers). It might be difficult if you have underground power lines; these usually make it harder for the compass and GPS to function at their usual pace. Repeat the above after power on. If *still* you cannot calibrate your compass, pick the aircraft up and turn it around 90 degrees. Memorize what the H telemetry value says before and after turning (see below picture for clarification). If it keeps on falling to 0 every time, your aircraft compass needs replacement. Please contact us via service@hubsan.com or PM us on Facebook.

4) I can’t get past Calib. Compass 2.

Answer: Place the aircraft on a flat surface and let it stay there for 20 seconds. Then, calibrate. This should solve the problem. In the very rare occurrence that it does not, please restart and calibrate by placing the aircraft on a flat surface and letting it stay there for 20 seconds. Should you have any questions, contact us or reach out to the Hubsan community.

5) I’m in South America/South Africa and can’t get past the compass calibration!

Answer: Use the suggestions listed above. If you get stuck at Calib. Compass 2, please email us (service@hubsan.com). The magnetic inclination of where you are will likely require additional assistance firmware or hardware-wise. Please do not try and make it work on your own; we will help you.

Compass calibration issues usually fall into the above categories. Should you experience anything outside of what we have described above, please post below or contact us (via Facebook PM or service@hubsan.com).
