The document provides instructions for connecting an MSP430G2553 microcontroller board to an AT-09 BLE module and establishing serial communication between them. Key steps include connecting the GND, VCC, RXD and TXD pins between the devices, initializing serial communication at 9600 baud, and sending an "AT" command to verify the connection is working properly. It recommends downloading a BLE TERM Android app for testing the Bluetooth Low Energy connection and notes that the service will need to be changed to read and write data.
Msp430 g2 with ble(Bluetooth Low Energy)
- 1. MSP430G2 with BLE Code: void setup() { Serial.begin(9600); /* Define baud rate for serial communication */ Serial.println("AT"); } void loop() { String str = ""; while (Serial.available()) { Serial.write((char) Serial.read()); delay(1); //wait for the next byte, if after this nothing has arrived it means the text was not part of the same stream entered by the user } } Board: MSP430G2553
- 2. BLE: AT-09 AT-09 GND <-> Any Arduino GND Pin AT-09 VCC <-> Any Arduino 5V Pin or 3.3V Pin Turn on you Arduino, you should see the AT-09 led blink. Let’s connect the TXD and RXD pins with the Arduino like this: AT-09 RXD <-> Arduino PIN 3 AT-09 TXD <-> Arduino PIN 2 After that, we can begin the serial communication by calling Serial.begin(9600) and send the first command Serial.println(“AT”). The AT command allows to verify that we are correctly connected and return “OK” in that case. It acts like a ping command.
