Usage

The following Commands are availabe via USB-Serial (115200 Baud):

• filter [mac] -> set MAC-Address of the searched device

• station [-v] -> list all availabe wifi-stations in 2.4G/5G Spectrum

• scan [from] [to] [-v] [-r] -> look for MAC-Addresses on specified channels

  • Channel 1..13 for 2.4 GHz (802.11b/g/n/ax)
