Connecting finger scanner with duo


#1

Hi,
I want to connect the RedBear Duo with a Finger scanner like this:-


This device specification says that it has Bluetooth V2.0+EDR, Class II.
I want to know whether Duo (Bluetooth v4.1) can connect to this peripheral (Bluetooth v2.0) and can receive the barcode number from it. If it’s possible, it would be great if I can be guided how to do this.
Thanks.

Hi @vrgdubey, The Duo only support BLE 4.1, though the on-board bluetooth chip is compatible with classical bluetooth spec. To benefit from the classical bluetooth relevant features, you have to develop firmware for Duo using WICED-SDK.
