I am trying to establish connection between two BLE (BT43) through AT commands from an Arduino Uno. I am not getting any response from the AT commands. The connections are as follows:
Arduino Tx --> BLE Rx Arduino Rx --> BLE Tx Arduino 3.3v --> BLEVcc Arduino Gnd --> BLE Gnd
Can someone please help me with this? Thanks in advance! this is my code
#include <SoftwareSerial.h>
SoftwareSerial BTserial(6, 7); // RX | TX
const long baudRate = 115200;
char c=' ';
boolean NL = true;
void setup()
{
Serial.begin(9600);
Serial.print("Sketch: "); Serial.println(__FILE__);
Serial.print("Uploaded: "); Serial.println(__DATE__);
Serial.println(" ");
BTserial.begin(baudRate);
Serial.print("BTserial started at "); Serial.println(baudRate);
Serial.println(" ");
}
void loop()
{
// Read from the Bluetooth module and send to the Arduino Serial Monitor
if (BTserial.available())
{
c = BTserial.read();
Serial.write(c);
}
// Read from the Serial Monitor and send to the Bluetooth module
if (Serial.available())
{
c = Serial.read();
BTserial.write(c);
// Echo the user input to the main window. The ">" character indicates the user entered text.
if (NL) { Serial.print(">"); NL = false; }
Serial.write(c);
if (c==10) { NL = true; }
}
}
