I am working on an ESP32-C3 Mini, which will act as a remote controller with multiple buttons. When a button is pressed, the ESP32-C3 Mini will send the corresponding data to another ESP32-S3, which will act as the BLE Central device.
Can anyone guide me on where I can find example code or reference projects for this type of BLE communication?
You could use ESP-NOW to send messages from one ESP32 to the other. Best way is to use MicroBlocks to program the ESP32 and the MicroBlocks extension to communicate with the boards from App Inventor.
