What BT version?

Trying to figure out what BT version the board runs. While I’m waiting for my board to arrive

According to the datasheet for the uBlox NINA-W102 module used for WiFi and Bluetooth communication on the MKR WiFi 1010, it's 4.2.

thank you kindly... just trying to get my bearing on this new chip/dev platform... can you possibly point me to the specs? I'm interested if the BT has some decent range (over 100 ft LOS).

Here you go:

Wow did I read that right? 400 m (1/4 mile) using the internal/pin antenna? Has anyone tested this and what sort of bit rates are we talking about. That seems incredible to me.
