Software WiFi emulation

Description of the feature you're suggesting.

Bluetooth and WiFi both operate in broadly similar RF range: 2.4 GHz. Although there are significant differences between the two communication technologies, the radio hardware itself can produce either signal.

This is called Cross-technology communication (CTC), which is a particular technology that enables direct communication between heterogeneous devices that use different wireless standards.

A lot of research has been done in this area in recent years, and it is now a proven fact that commercial wifi devices can emulate bluetooth signals with clever software, and vice versa: vanilla bluetooth devices can also communicate natively with wifi access points without any hardware modification.

It would be a breakthrough hack, if Flipper Zero could employ such technology, and can emulate WiFi without any external hardware addon.

Here are some research on the subject to start with:

  1. Unify: Turning BLE/FSK SoC into WiFi SoC
  2. BlueFi: Physical-layer Cross-Technology Communication from Bluetooth to WiFi
  3. FLEW: Fully Emulated WiFi

Anything else?
