I hoped the Firmware Update would help, but after 3 days the System is offline again.
Can you help please?

Thanks for Support

@broker The firmware version is the latest. Did you try turning off the WIFI on the screen and turn on again to test if it can connect stably?

Wenn I turn off and on WiFi on the screen, it works

I‘m dealing with the same problem, that my AC300 looses the wifi connection after a couple of minutes. I can always reconnect by switching off/on the wifi on the display of the AC300. Wifi signal is excellent an I set the network to 2,4GHz.

Serial number: AC3002145000796518
Communication: IoT2144000466583
IoT: v9014.09
ARM: v4037.05
DSP: v4036.07

Could anyone solve the problem?
Best regards

@bluetti_burgmeierjgmailcom Please check again if there is a software update.

Unfortunately there is no update in the app available (coupled via bluetooth).

I have my iphone on wifi and my ipad on bluetooth. There’s only a problem if I try to connect with both on wifi or both on bluetooth at the same time. It’s the same for some of my other gadgets.
I prefer bluetooth because it connects faster than wifi, especially when I just want a quick look at SoCs.

@bluetti_burgmeierjgmailcom Please check the SN of the AC300 or take a photo for me.
