SPP-C Bluetooth Module (Alternative to HC-05 HC-06)

Description

What is the SPP-C Bluetooth module? The SPP-C Bluetooth module is a wireless device that allows connecting Arduino devices to smartphones or computers for sending and receiving data wirelessly. It is an economical alternative to HC-05 and HC-06 modules. Features: An economical alternative to HC-05 and HC-06; Enables wireless data communication with Arduino, smartphones, or computers; What is it used for? The SPP-C module can be used to create devices such as temperature sensors that send real-time data to your mobile device or computer. It is compatible with various Arduino circuit types. Tutorial: How to Use the SPP-C Bluetooth Module The SPP-C Bluetooth module is an economical alternative to the famous HC-05 and HC-06. It allows connecting Arduino devices to smartphones or computers for wireless data transmission. What is needed: Arduino Uno, USB A-MicroB cable, Arduino IDE Steps to connect the SPP-C module to Arduino: TX of the module to pin 0 of Arduino, RX of the module to pin 1 of Arduino, GND and VCC as required. Install the SoftwareSerial library in Arduino IDE. Open a new sketch in Arduino IDE and include ‘SoftwareSerial.h’. Create an instance of the SoftwareSerial class with the TX and RX pins used. Initialize the SPP-C module by sending AT commands. Refer to the datasheet for detailed specifications. Write code that allows the Arduino to send data to the Bluetooth module when receiving data from the computer or smartphone. Configure the mobile device application (such as Serial Monitor) for communication with the SPP-C module. Test the connection and data transmission. Example code: // Include ‘SoftwareSerial.h’ #include // Create SoftwareSerial instance SoftwareSerial bluetooth(0, 1); // RX | TX void setup() { Serial.begin(9600); bluetooth.begin(9600); } void loop() { if (bluetooth.available()) { int incomingByte = bluetooth.read(); Serial.write(incomingByte); // Send data to the computer } } Mini-project: Create a real-time temperature sensor that sends data to your smartphone or computer via the SPP-C Bluetooth module. Common errors: Incorrect module configuration, connecting TX and RX to the wrong pins, failing to properly check the connection, entering incorrect data during configuration. Recommended accessories: DS18B20 Temperature Sensor, 16×2 LCD Display Module, DS3231 RTC Module, PIR Motion Sensors. Frequently asked questions: Is the SPP-C module compatible with HC-05?
