1. Overview
1.1 Introduction
Small in size and low in power consumption, E104-BT5032A is a serial-to-BLE module based
on BLE 5.0 working at 2.4Ghz. It works as both Bluetooth master and slave.
Based on nRF52832 from Nordic, the E104-BT5032A module is developed by Chengdu Ebyte.
AT commands are available for parameter setting, thus operation is simple and fast. There are
Bluetooth master, slave and observer modes. It functionally supports low-power broadcast, data
transparent transmission, and air configuration. It is widely used in smart wear, home automation,
home security, personal health care, smart home appliances, accessories and remote control, automotive, lighting, industrial Internet,
intelligent data acquisition, intelligent control, etc. The maximum continuous transmission baud rate is 921600bps.
