Help me with converting my Bluetooth Classic Code to Bluetooth Low Energy

[MelodyApril]

It is required to keep everything working exacly the same, with the only difference being that I'd like the code to use BLE, meaning any line of code related to BT Classic has to be replaced with its BLE equivalent (which is a bit over me atm, even after reading through the BLE examples available publicly).

Here is my code:

I tried replacing some code lines with BLE related lines but the callbacks started giving errors, especially after getting rid of the BluetoothSerial SerialBT; line.

If anyone can help me with the process it'd be awesome. I'm trying to make the device compatible with both Android and iOS, the reason behind the conversion, as of right now it only works with Android OS and I can't test it on iOS devices.

Here examples of BLE

BLE ESP32. Bluetooth. Send. Receive. Arduino IDE. Multitouch

Hello friends, I'll write in this topic about BLE on ESP32, send and receive text, with clock and without clock. Notify. I'll use the codes of Neil Kolban. 0.- Board D1 R32 ESP32. This is a cheap card ($ 5) with the dimensions and shape of the Arduino UNO, but with the ESP32. [esp322pin_h] Search images: D1 R32 ESP32 This card has classic Bluetooth, BLE, WiFi, ADC, DAC, and more feature. This card can be programmed with the Arduino IDE. [comparativa] There is another smaller ESP32 mode…

HM-10. BLE. Arduino UNO. Notify. Bluetooth. AT. iBeacon. Arrhythmia

Hello friends, I bought a wonderful HM-10 module with BLE for only $ 2. I have written my experiences on this Spanish website (http://kio4.com/arduino/161_HM10_BLE.htm) and I would like to share a summary in this Community. I have used the BluetoothLE 20190701 extension. I have connected the module to an Arduino UNO [hc10_3] I tried to use these libraries, but they did not work for me in Arduino UNO. CurieBLE.h is for Arduino 101 (Curie). ArduinoBLE is for Arduino MKR WiFi 1010,…

Update: I've manage to update most of the functions in the code but it still returns an error at the moment.

Update: I've managed to add a bit to my new BLE version of the code but the RSSI keeps showing as 0 no matter what connects to the Esp32.
