Bluetooth low energy compatible with arduino

Hi all,
I am trying to find a bluetooth low energy which can be programmed as a bluetooth scanner and save the scanned bluetooth id and RSSI. I am wondering if there is any technology around for that. I came accross Tinysine Serial Bluetooth 4. Do you think I can do such a thing with this.

Thanks

The device is just another serial device as far as Arduino is concerned. There is an AT command to query RSSI. I guess you just leave it in AT mode if you want to continuously check this,
