Bluetooth works like a crap on 2018 MM

[avxkim]

I've read many topics about bluetooth interference. When i was using USB keyboard/mouse i had no problems. But now i switched to Magic Keyboard 2 / Trackpad 2, they're not disconnecting, but i have cursor / keyboard stuttering from time to time, it's very annoying. I'm not using USB ports at all.

Did someone managed to fix this interference issue?

Strange I’ve got a MM running with exactly those Apple Bluetooth devices, and it’s in a server cabinet with bucketloads of USB3, networking and power cables. Works fine no issues (unlike my 2017 iMac which does have BT issues with very little other kit around it).

What transmitting frequency is your router on? If your router is using the 2.4 GHZ band and your router has dual bands, switch to the 5 GHZ band instead. The 2.4 GHZ band will sometimes cause interference with BT.

My router stands next to MM and i'm already using 5ghz. I use wifi for universal clipboard mainly, because MM is connected via ethernet.

FYI, universal clipboard works without Wifi too (using Bluetooth). Might be worth testing whether it makes any difference turning Wifi off on the Mini

I tested it already, it works 1-2 hours, then stops working. I can't copy anything from ios to mac and vice versa, only when i turned on wifi (also connecting to a network is mandatory, otherwise it won't work).

Forgot to mention, with wifi completely turned off (not on, but not connected to any network) i have no issues with bluetooth, but i've read only 2.4GHZ is interfering with bluetooth, so why my turned on wifi, but not even connected to a 2.4ghz is causing problems?

continuity seems to throw it off as well.

I had lots of issues with Bluetooth and Wifi. In the end it was an external hard drive I had near it. Seems they are very prone to interference.

I have external HDD attached to a time capsule, but it's on the other side in the room.

I have literally nothing connected except keyboard via LG (nothing to the mini except the screen) and i get bluetooth freezes.

This is clearly yet another hardware defect that Apple refuses to acknowledge and fix

"HDD on other side of the room."
Did you buy a high quality cable?

This is the one issue that is inching me towards not buying another MM18, I've not experienced trackpad dropouts on any other device. I take it no improvement since new Mojave?

I have no issues with my Logitech keyboard and mouse. Bluetooth works fine.
