I am needing to have one embedded Bluetooth device open 2 simultaneous connections
one with a mobile device (iPhone or Android) to receive audio
a second connection with another embedded Bluetooth device to exchange small packets of data (remote control)
Does anyone know how to do this and what devices can be used?
As far as I know, this isn’t possible to do. You may be able to find a Bluetooth module that allows connections to two separate devices at the same time, but I’m not aware of any that allow that without some sort of firmware hacking. It might be easiest to just use two different Bluetooth modules and have each one connect to different devices.
