General Details

Basic Functions

WH-BLE103 is low-power Bluetooth module which supports BLE4.2 protocol and user can realize communication through simple configuration. The module can be use for point-to-point transparent transmission and enctyption transmission. Module can work at master mode or slave mode. User can set one module as master, the other one as slave for transparent transmission. Or develop APP according to standard BLE protocol to communicate with module. BLE103 supports one-to-many broadcast mode and iBeacon protocol. And also support modifying 128bit format UUID to be compatible with other company BLE modules. WH-BLE103 is reliable BLE module with various functions and high compatibility.

 

Features

Compatible with USR-BLE101 in function and encapsulation, add external version and GPIO

Identify Packet function

Identity packet is used for identify the device when module works as TCP client/UDP client. There are two methods for identity packet. 

Identity data will be sent when connection is established. 

Identity data will be add on the front of every data packet.

Heartbeat Packet Function

Heartbeat packet: Module will output heartbeat data to serial or network periodic. User can configure the heartbeat data and time interval. Serial heartbeat data can be used for polling Modbus data. Network heartbeat data can be used for showing connection status and keep the connection (only take effect in TCP/UDP Client mode).
