Use a USB dongle whether it can connect more device.

I have a question about USB dongle, when use MasterEmulator to development Windows program whether can connect more device

The Master Emulator can only connect to one Peripheral at a time. If you need to connect to multiple devices, I'd recommend you to try the S120 SoftDevice, which can be connected to 8 Peripherals simultaneously.
