Could you put an iPhone or other smart phone near by, and turn off/on its bluetooth? In principle, when you turn on the bluetooth, you should see some packet printing on screen.

I have the exact same problem, I also try the btle_tx example and in seems to work since the SDR Bluetooth low Energy shows on devices on my ligth blue app in my phone, however not a single package shows when i run the btle_rx example.

Please also try to change the rx gain via the command line arguments.

I already chache de gain value a few times and start turnining on and off the bluetooth of an android smart phone and an Iphone without any succes, im using the Hackrf one btw, i´m attaching some pictures on this comments just in case.

[JiaoXianjun]

The antenna seems a bit abnormal.
Can you unplug the antenna (yes you don' need antenna)?
Then try some big gain values?

[FreddXINN]

I unplugged the antenna and try increase the gain step by step to the maximum value and also changing the channels without good results
