There are easy ways of preventing interference while using Bluetooth systems.
If there are multiple Bluetooth devices in the same area, try moving a couple for a better chance at a successful connection.
The closer your Bluetooth device is to whatever you are connecting it to, the better chance of a solid connection you will have.
Removing any devices that emit a frequency in the range of 2.4GHz to 5GHz from the area.
Don't try to connect to a device in a separate room through walls made of concrete, metal, or plaster.
While using Bluetooth devices, you can run into a lot of issues with your connection.
These complications can be a result of your technology being too close to microwaves, a cell phone, or wireless transmitter operating in the 2.4-5 GHz range.
Any wireless device that operates at the same frequency as your Bluetooth device can cause an interference in the connection.
Devices such as external hard drives with poorly covered cables can interrupt a connection if they are close enough to your device.
Wifi routers and even simple objects like baby monitors or video cameras can cause a disruption.
Materials such as metal, concrete, and plaster can easily cause interference while materials such as wood or glass produce little interference.
