DopeScope 2.0

Wi-Fi Scan

The default screen in the Wi-Fi menu will show a continual scan of the advertised networks within range. The display shows the RSSI, encryption type, channel and SSID (if not hidden) for the AP. The display will update roughly every three seconds. Using the buttons, you can pause the scan and scroll through the list of APs. Pressing the SELECT button on an AP will bring up an option menu which will allow you to get more details, follow the AP or return to Wi-Fi Scan or the Main Menu. If you scroll back to the top of the screen, the device will resume scanning. Pressing the SELECT button while actively scanning will return you to the main menu.

Wi-Fi Details

The Wi-Fi Details screen will show you the normal information about the AP (ESSID, BSSID, channel and encryption). The scope will then lock to the channel of the AP and listen promiscuously for all packets coming from the AP. The RSSI value will update every time a packet is observed from the AP and a chart at the bottom of the screen will show the activity of the AP in packets/sec. This will allow for better AP hunting. Pressing the SELECT button will return you to the scanning screen.

Wi-Fi Snoop

The Wi-Fi Snoop mode allows you to observe more activity related to the AP. The device will tune to the channel used by the selected AP and begin listening for all packets to and from the AP. A list of clients will be shown. By default, the list is sorted by the time(secs) since the client was last seen, but by pressing the UP and DOWN buttons you can change this to sort by the last RSSI of the client or the total number of packets seen from the client. This mode allows for greater insight into client devices and will allow for finding rogue clients. Pressing the SELECT button will return you to the scanning screen.

BLE Scan

The default BLE screen shows a survey very similar to the Wi-Fi SCAN mode. You will be able to see any BLE device in range as well as their RSSI and what capabilities are being advertised. Four flags represent the “Appearance Data,” “Manufacturer Data,” “Service Data” and “Service UUID” if available. Using the UP and DOWN buttons, you can scroll through the list of devices. Pressing the select button on a device will open a details page. If you scroll back to the top of the screen, the device will resume scanning. Pressing the SELECT button while actively scanning will return you to the main menu.

BLE Details

The BLE details page is similar to the Wi-Fi details page. It will show the name of the BLE device (if advertised), the MAC address, the last observed RSSI (continually updated), seconds since last seen and the extended information included in the advertising frame. When possible, it will attempt to identify the manufacturer of the device if enough information is provided in the advertising frame. A chart in the lower half of the screen will show the RSSI over time to help locate the observed device. Pressing the SELECT button will return you to the BLE scan.

* Be aware that BLE devices regularly change their MAC addresses to avoid tracking. If a device seems to disappear, return to the scanning menu to try to relocate it.
