Hello, reopening.

iOS Devices do not support classic BT SPP (BTSerial). Only BLE works with iOS

@sirapol I am just posting a comment from IDF issue about BT Classic on iPhone. Take a look to see the options you have: https://github.com/espressif/esp-idf/issues/6513#issuecomment-776244467

Also link to Apple's supported Bluetooth profiles on iOS and iPadOS may help.
