How to use the Bluetooth Low Energy on the ESP32?

[@ElectronicsSimplified7]

The upload speed should match with the Baid rate (not necessarily) But the ESP32 devkit v1 functions well and has no uploading issues with 115200 upload speed. You could refer to the other videos where i have explained the errors of esp8266.

can we control the range of Bluetooth devices? I am using ESP032 and want a 2-meter range, not 10 meters. Please let me know how can I do it...
