Espressif's flagship chip ESP32 has passed the Bluetooth LE 5.0 certification!

According to Espressif's official WeChat account, on November 30, 2019, Espressif's flagship chip ESP32 passed the Bluetooth LE 5.0 certification of the Bluetooth Technology Alliance (Bluetooth SIG).

This means that the protocol version supported by ESP32 Controller has been upgraded from Bluetooth LE 4.2 to Bluetooth LE 5.0, which has higher stability and compatibility. Bluetooth LE 5.0 is becoming the mainstream version of current Bluetooth chips. In this way, ESP32 will be more compatible and adaptable to other Bluetooth 5.0 chips, and play an advantage in the field of Bluetooth and the Internet of Things.
