Asiair Crashing

dseaman6745T

Have a 3 1/2 yr old AsiAir. Has worked nearly flawlessly since new. Last 2 nights, noticing almost constant crashing of the AsiAir. Will polar align fine. Start the guiding routine; sometimes completes the calibration, more often get a reconnect message. After reconnecting in 1 minute, the main camera, guiding camera, mount, and focuser are all disconnected. Can reconnect all of them. Starting the guiding sequence, same result. Have reloaded firmware to app twice, done hard reset for AsiAir. All cables look good. Have tried a second battery, same result.

Any suggestions before sending the AsiAir out for inspection and potential repair?

Did it update and you only see these issues after the update?
What firmware version are you running? The actual version number - don't say "latest".
Do you use and Android or Apple device to run the ASIAIR App?

Have you updated your app hence firmware version recently? What versions are you running?

Asiairs are notorious for suddenly causing problems when they were previously working perfectly fine once people update.

Roll the firmware back to factory, and uninstall your app, and reinstall an older app version. You need an older app version because they contain the firmwares, if you reconnect to a rolled back asiair again with the up to date app, once connected you'll be forced to update the firmware of the unit and you'll be back to square one again.

Firmware version currently running for AsiAir is 2.3(11.56). That was done after the first issue with crashing occurred on 3/23/25. I had been running an earlier version of the software (not sure which one) until then with no issues. This was done on the APP ( after re-installing the APP) with reload to factory firmware and then accepting request to update to current firmware (2.3 (11.56).

I started crashing before updating the software. The update to 2.3 (11.56) was a part of the plan to fix.
Firmware is 2.3 (11.56), has been updated and reloaded 3 times now.
Running off Apple device running iOS 18.3.2 which was updated last week. The crashing has occurred after the Apple software update which makes me think there is a compatibility issue although I don't see anything on the net indicating others having similar crashing problems post 18.3.2 update.

Well this narrows it down. Just did a Google search for iOS 18.3.2 Wi-Fi issues and there's a bit out there:

Oh - and make sure you're not running a VPN on your Apple device.

I'm still using 2.1.5 with firmware 11.08, I've read many forum posts with people with issues for firmwares/app with v2.2 and 2.3. I don't understand how a stable working version suddenly becomes unstable after an update. This happens over and over again. It happened quite badly after v1.9 of the app too when it was updated to V2.0 (note this means firmwares too as they're often updated when the app is).

Astrop note this means firmwares too as they're often updated when the app is).

FYI: The firmware on the ASIAIR is always updated when the app version is. They're a matched set.

It's for this reason app auto update on your device for the ASIAIR App should be turned off. You can do this for just the ASIAIR App on Android. You have to do it for all apps on Apple.

Follow up. Did about 5 hours of in-house testing yesterday; isolating all the components in an effort to determine which one was the culprit. Ended up being the 533MC camera which was using 12v power off the AsiAir. Consistently, the AsiAir would crash at 7-8 minutes after starting if the camera was powered on (cooler) and activated on AsiAir. Had no issue with focuser, guiding camera, or mount as long as the camera was not attached to the AsiAir. Initially thought this was a data cable problem but found that the power stability was in fact the issue. When powering the 533MC using another power port (the AM5 accessory power port), no more crashing. All these tests were done in the basement with no guiding so, not confirmed yet in actual imaging session.

Interesting how this occurred suddenly after years of powering the camera using an AsiAir port with no upset. Possible the AsiAir is getting ready to crash for good but for now, back to it tonight for the real test
