Bluetooth Classic
Connect to your project using Classic Bluetooth modules (e.g. HC-05, HC-06).

Bluetooth Classic is ideal for continuous serial communication between two devices.

Bluetooth Low Energy
Connect to your project using Bluetooth Low Energy modules (e.g. HC-08, BT-05).

Bluetooth Low Energy (BLE), works differently to Bluetooth Classic. Bluetooth Low Energy can be thought of as a notice board with lots of (typically 20 byte) notices (called characteristics). Multiple devices can connect to the BLE device and read or write on the notice board. By reading and writing on one of the characteristics, we can emulate serial communication. If you use BLE modules, keep this in mind and try to keep each message to under 20 bytes to reduce the chance of loosing data. BLE is more suitable for low power sensor type applications rather than the continuous serial communication done here with these Bluetooth UART modules.

USB
Connect your project using the micro USB port of your Android device. It is also an 58.11.88.57 04:08, 20 August 2022 (UTC)
