E104-BT40X Dual-Mode Bluetooth Module Overview

The E104-BT40X dual-mode Bluetooth module is a serial-to-dual-mode Bluetooth slave module developed by Ebyte, supporting Bluetooth BLE4.2 + SPP3.0 protocol versions, i.e., low-power Bluetooth BLE and classic Bluetooth SPP Profile. It can freely switch between BLE low-power Bluetooth and classic Bluetooth, operating in the 2.4GHz frequency band.

The E104-BT40 series dual-mode Bluetooth module uses universal AT commands to set parameters, ensuring simple and quick operation. The Bluetooth module only supports the Bluetooth slave role. Through this Bluetooth module, traditional low-end serial devices or MCU-controlled devices can achieve wireless data transmission. It is a low-cost, easy-to-use, and reliable data transmission module.

Common Application Scenarios of Bluetooth Module
