ABSniffer USB Dongle 502 works as USB 2 UART mode. It can work with Windows/Mac/Linux/Raspberry PI

  • Size 68mm x 26mm x 12mm
  • Micro controller TI CC2540


Raspberry PI

On a Raspberry Pi the device shows up as /dev/ttyACM0.


  • Install package kmod-usb-acm first
  • After installing, you will get some log like
[47056.710000] usb 1-1: new full-speed USB device number 4 using ehci-platform
[47056.940000] cdc_acm 1-1:1.0: This device cannot do calls on its own. It is not a modem.
[47056.950000] cdc_acm 1-1:1.0: ttyACM0: USB ACM device

And now

# ls /dev/tty*
/dev/tty      /dev/ttyACM0  /dev/ttyATH0  /dev/ttyS0

After that it's just a cat /dev/ttyACM0 to read the output.

Thanks Jason for his sharing!
