1. Overview
1.1 Introduction
E104-BT20 Bluetooth serial communication module is a data transmission
module based on Bluetooth Specification V2.1 BR / EDR Bluetooth protocol.
The working frequency is 2.4GHz ISM, and the modulation method is GFSK.
The module's maximum transmission power is 3dBm. It’s packaging method is stamp hole and It has onboard PCB
antenna which enable the module to have a 50-meter communication distance.
The E104-BT20 module integrates the transparent transmission function and the master-slave function and it’s
offers instant access to user. The E104-BT20 supports AT instruction, so users can set parameters such as module
master-slave role, serial port baud rate, device name, etc., which is flexible and convenient to use. It also supports
point-to-point connection from master to slave module to achieve fast data transmission and the data transmission
is stable and efficient. In slave mode, it supports a maximum baud rate of 921600bps. It is a simple and efficient
data transmission module that minimizes the developer's work and project development time.
