### Known working adapters
<div class='note'>
Known working adapters list adapters that do not meet high-performance requirements but will generally work. These adapters vary widely in performance and may take as long as thirty seconds or more to establish a connection. These adapters may also miss advertisements such as button presses or temperature updates.

### Improving connection times
The connection time and performance vary greatly based on the Bluetooth adapter and interference. The below adapters are listed from best-performing to worst-performing:

### Integrations that require exclusive use of the Bluetooth Adapter
While newer integrations can share the Bluetooth Adapter, some legacy integrations require exclusive use of the adapter. Enabling this integration may prevent an integration that has not been updated to use newer methods from functioning.
