1. Overview
1.1 Brief Introduction
E104-BT40 module is a serial to dual-mode Bluetooth slave module based
on Bluetooth 4.2 + 3.0 version, namely low power consumption Bluetooth BLE
and classic Bluetooth SPP Profile, which can freely switch between BLE and
Classic Bluetooth, working at 2.4GHz.
The E104-BT40 module uses general AT commands to set parameters, and
the operation is simple and fast. The module only supports the Bluetooth slave
role.
Through this module, traditional low-end serial devices or
MCU-controlled devices can perform wireless data transmission. It is a low cost, simple and reliable data transmission
module.
