The latest generation of smartphones are designed to support multiple Bluetooth connections at once.
In theory, Android devices are able to handle between 4 and 8 connections and iPhone devices will run up to 6. However, some smartphones, even brand new, have variable Bluetooth performance. For those ones, connection problems with the app/device could sometimes be observed. Of course, we are here to evaluate your device performance if you need us.
