Version 0.5.0 releases are being synchronised across Flipper and ESP32. The biggest changes to v0.5.0 is the addition of Bluetooth Classic and BLE scanning and homing/following features.
Plus lots more.
Compatible with ESP32 and ESP32S2.
Incompatible with ESP32S3 and ESP32C6 - I'll start working on that soon.
