Introduction

E104-BT53 is a serial port to BLE Bluetooth module based on Bluetooth protocol version 5.2. It is small in size, low in power consumption, and works in the 2.4GHz frequency band. The module uses general AT commands, and the operation is simple and fast. Modules can be widely used in smart wear, home automation, home security, personal health care, smart home appliances, accessories and remote controls, automobiles, lighting, industrial Internet, smart data collection, smart control and other fields.

Features

• Support Bluetooth BLE 5.2 protocol
• Simple and easy to use, without any Bluetooth protocol application experience
• Support all features of BLE 5.2: 2M physical layer, long - distance, fast extended broadcast
• Support BLE single - master role, single - slave role, master - slave role and Beacon role
• The module can act as the master role and the slave role at the same time. When connected by other master role devices, it can also connect to other slave role devices
• Support OTA remote upgrade function (E104 - BT53A3 only)
• The master role supports multiple connections: under a single master role, up to 8 slave role devices can be connected at the same time; under the master - slave integrated role, 7 slave role devices can be connected at the same time, and can be connected as a slave role by another master role device at the same time; The default connection interval is 20ms, the connection is fast, and it is compatible with other BLE modules of the company
• The user interface adopts the general serial port design, the hardware flow control supports full - duplex communication, the minimum baud rate supports 1200bps, and the maximum supports 921600bps
• Support serial port or mobile APP to send AT commands
• Support AT command software reset module
• Support AT command to set connection interval to control different forwarding rates and adjust dynamic power consumption
• Support AT command to set transmit power, broadcast interval, serial port baud rate, broadcast name, etc.
• Support AT command to modify service UUID of slave role
• 2K serial port cache, the serial port receives user MCU data and automatically divides it into 244 bytes, and the timeout time is 100 milliseconds; High - speed transparent transmission and forwarding, the actual measurement can reach 50KB/s when the signal is good
• Support to modify the physical communication rate: 1M, 2M and LE Coded (125K and 500K)
• The slave role supports custom broadcast data, a maximum of 26 bytes
• The slave role supports extended broadcast packets, and a maximum of 251 bytes of extended broadcast can be customized
• Support setting long - range broadcast package (Long Range/LE_CODED)
• The module is compatible with other models of the company
• Sleep power consumption is as low as about 2uA
