How to send messages using bluetooth

[GreenNarae]

Hi!
I purchased esp32 this time and am working on the project.
Led control was successful using Raspberry Pi. But I don't know How to do with the next Bluetooth communication.
I want to send texts like a keyboard using Bluetooth. But since I'm new to esp32, I don't know where to approach it.
It would be very helpful if you, the experts, advise me.
Thank you!

Hi,

It sounds like you want to make the ESP32 act as a Bluetooth (BLE) keyboard. Which is to say, implement the BLE HID service.

Please see https://github.com/micropython/micropython/pull/6559 for an example implementation of this.
