How many bluetooth connections at once
Most Android devices can connect to two or five Bluetooth devices simultaneously, while others support up to seven devices. The number of supported connections depends on the Bluetooth module your device is equipped with.
Bluetooth 5-enabled Android devices support up to seven simultaneous Bluetooth connections. However, your manufacturer or carrier may limit this number. The quickest way to test that is actually to try to connect to seven devices via Bluetooth. The good news is that you should be able to activate additional Bluetooth connections in Developer mode.
