Packet loss when Bluetooth scanner is enabled

[Plotter]

Hello,

 

I have an Pro 4pm and it is connected on channel 11 of my wifi AP. The AP is about 5 meters from the Pro 4pm and device is in a plastic box.

I have created a script to scan bluetooth and whenever it finds my bluetooth device, it turns on the lights. I have noticed that whenever I start the bluetooth scan (active or not) I get packet losses on the wifi side. If I disable the scan, everything works fine.

Anyone else have similar issue or could point out to the right direction?

I noticed just the same with Shelly PlugUS.
