consumption, working at 2.4GHz.

E104-BT52 is developed by Chengdu Ebyte Electronic Technology Co., Ltd. based on the dialog DA14531 chip. The module

uses general AT commands to set parameters, and the operation is simple and fast. The module only supports Bluetooth master, slave

and observer modes. The module functionally supports low-power advertising, data transparent transmission, and air configuration.

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. The maximum

baud rate is 460800bps for data transmission.
