DFRobot_ESP32_WiFiBLE

This library is based on ESP32 master BLE applications. It can connect 4 slave devices at the same time, and can connect different Bluetooth through setting different service ID. At the same time, an example of combining WiFi and BLE is also given.

Installation

Download the directory "DFRobot_ESP32_WiFiBLE » and move it into the "libraries" directory inside your sketchbook directory, then restart the Arduino IDE. You will then see it listed under File->Examples->DFRobot_ESP32_WiFiBLE.

Usage

The library is instantiated as an object with BLE provided to read and write data from BLE. #include "DFRobot_ESP32_BLE.h" DFRobot_ESP32_BLE ble;

void setService(uint16_t ser)

Setting up peripheral service ID.

Example:

ble.setService(0xdfb0);

0xdfb0 is the serive ID for Bluno, so you can connect Bluno.

void setCharacteristic(uint16_t cha)

Setting up peripheral Characteristic.

Example:

ble.setCharacteristic(0xdfb1);

0xdfb0 is the Characteristic number for Bluno, so you can connect Bluno.

void setconnummax(uint8_t max)

Sets the number of connections from the machine

Example:

ble.setconnummax(2);

The max conncect number is 2.

void setconnectname0(String str)

Setting up peripheral's name,which serive will connected.

Example:

ble.setconnectname0("Bluno0");

void init()

Initalize ESP32 BLE device.

Example:

ble.init();

void begin()

Start running Bluetooth device

Example:

ble.begin();

String readdata(char *buf)

Read data from BLE.

Example:

char dataName[15] = {'\0'};
String bledata = ble.readdata(dataName);
