Is it correct that there are paths that are not unlocked in ble_gap_ext_connect? #20

Hi @KAMEDAkyosuke , if I have understood you correctly, I believe you are having issue with using extended connect API (ble_gap_ext_connect) on ESP32. We need to enable 'Extended Advertising' (BLE_EXT_ADV) feature for this API to work and ESP32 hardware does not have support for this feature. You can refer: https://www.espressif.com/en/news/BLE_5.0_Certification where it is mentioned that "Due to hardware limitations, ESP32 does not support such functions of Bluetooth LE 5.0 as 2M PHY, LE Long Range, and ADV Extensions"

@prasad-alatkar thank you for your replay😀 I didn't understand about the hardware limitations.
