1. Overview

1.1 Brief introduction

E104-BT51 is a serial to BLE Bluetooth slave module based on
Bluetooth protocol version 5.0, which is small-sized, low power
consumption, and works in the 2.4GHz frequency band.
E104-BT51 module is a serial to BLE Bluetooth module developed
by Chengdu Ebyte Electronic Technology Co., Ltd. based on TI
CC2640R2F chip. This module uses AT commands to set parameters,
and is easy to operate and configure. The module only supports the
Bluetooth slave mode. The module functionally supports low-power
broadcasting with changeable content, transparent transmission of data and continuous transmission of files with variable
baud rate. It supports air command configuration and IO port level reading , IO port switch level setting, PWM output
with variable frequency and period, AD analog acquisition, Bluetooth battery voltage service. The module can be widely
used in smart wear, home automation, home security, personal health care, smart appliances, accessories and remote
control, automotive electronics, lighting industry, industrial internet, smart data collection, smart control, etc. The
module supports a maximum baud rate of 921600bps and a 2M PHY air rate of Bluetooth 5.0.
