Thank you all for the explanations.
On the product page: ARDUINO UNO WiFi REV2 — Arduino Official Store
There is no mention of BLE or bluetooth, and i think this is a BIG mistake especially since the board supports it and this feature should definitely be stated on the 'Overview' page and not just mentioning 'Wi-Fi' since it easily misleads into believing that there is no Bluetooth support and we'll just click away to somewhere else to find a Bluetooth-supported Arduino board.
I believe that with the soaring popularity of ESP modules which are sold much cheaper and also are more powerful than Arduinos (i'm not sure if i'm allowed to mention ESP here? if not, i will edit my post) which work perfectly fine with the Arduino IDE and have integrated WiFi and BLE, this is undoubtedly slowing down the adoption of Arduino MKR boards and the Uno Wi-Fi Rev 2. I wonder if there is a solution to this? How does Arduino co-exist with ESPs when they seem to be taking over the world like a storm, especially with the rise of wireless control and communication with makers and hobbyists, for IoT, etc.
