Simultaneous Bluetooth and Bluetooth LE connections, is it possible?

Question

I'm currently trying to develop a piece of software that would require to connect one bluetooth "classic" device and at least 2-3 Bluetooth Low Energy devices. And of course communicate with these devices, so it's not enough to be able to pair the devices but also to connect and communicate with them.

I'm using Nexus 4 (Android 4.3) as a unit which connects to these Bluetooth and Bluetooth LE devices.

Is this possible or is there some kind of restriction that only one, or the other, kind of Bluetooth devices can be connected simultaneously?

Answer 1

I'm pretty sure there's no restriction in the Bluetooth standard for having both regular and LE connections at the same time (on the host side).

However, I think there may be a restriction on having both a regular and a LE connection to the same device at the same time. There's no reason to do that, though, as all the LE functionality is available through a regular Bluetooth connection on devices that have both abilities.

EDIT: You can restrict a device to not allow both LE and BR/EDR or you can also allow it. I'm not sure why you'd want to connect both on the same device, though.
