LAUNCHXL-CC1310: Sniffer connection problem

Part Number:LAUNCHXL-CC1310

Hi.
I am trying to set up a sniffer fw on LAUNCHXL-CC1310 to sniff sub1ghz packets coming from CC1350 sensortag.
I used C:/ti/simplelink_cc13x0_sdk_1_30_00_06/tools/ti154stack/TiWsPc2/sniffer_fw/bin/sniffer_fw_gfsk_50kbps_868_915.hex with Flash Programmer to flash the launchxl, and it flashed successfully.
When the device is turned on, the green led is blinking and I can see in UART the string "TI Packet Sniffer ver.1.0.0" printed every second.

I installed smartRF packet-sniffer 2 from TI but when I turn it on, it cannot find any devices, also when I press "Search for new Devices".

Can you please help, How do I set up the sniffer?
