Collect Bluetooth Low Energy Data
Adafruit has the Bluefruit Sniffer requires a host PC instead of an arduino UNO (http://www.adafruit.com/product/2269) it basically has a nrf51822 module which talks to the PC over a UART using the FTDI usb to Serial converter chip. I suspect that you could probably get a similar nrf51822 module and flash the sniffer firmware( found here: https://github.com/adafruit/Adafruit_BluefruitLE_Firmware/tree/master/sniffer/1.0.1)use the Jlink to flash the firmware onto the BLE module and use that to communicate with the arduino UNO over a uart connection. Hope that helps, Good luck!

you can try using one of these modules maybe:
