I purchased a DF Romeo BLE V1.0 From DigiKey. I followed the instructions to connect to the pc running XP. I am new to Arduino and am need of some help.
I get a Error: Programer is not responding. Not in sync: resp=0x60
I have tried numerous time with different driver etc. I believe the board is ok and the problem is either the driver or in the pc com port. I cannot find much info on the help forums. Can anyone give me advice? It would be much appreaciaed
- Hardware preparation: a BLE-Link, a RoMeo BLE, a PC and a micro USB line.
- Software preparation: serial debugging assistant, Arduino compiler.
- The operation:
Step 1: Set two bluetooth devices as a master and a slave (bluetooth communication should be established between a master and a slave machine). Here we set BLE-Link as the master, while RoMeo BLE as the slave. Specifically, we first connect the BLE-Link to the PC via a USB cable and the BLE-Link would be identified as a serial port equipment. Then open the serial debugging assistant (take the V1.8 version of BLE-Link firmware to for example), send the "+++" to BLE-Link, proving that you have entered the AT command Mode when receiving "Enter into the AT command Mode". Send the BLE-Link "AT + SETTING = DEFCENTRAL" (remember to select a new line to send), meaning that the BLE-Link has been set as the master when receiving "OK". Accordingly we set the RoMeo BLE as the slave by connecting it to the PC, open the serial debugging assistant and send "+++" and "AT + SETTING = DEFPERIPHERAL".
Step 2: Arduino program on RoMeo BLE, which is used to parse the data commands to open or close the light L.
The code is as follows:
int led = 13;
char rcv_buf[10]; // Receive command arrays.
void setup()
{
pinMode(led, OUTPUT);
Serial.begin(115200);
}
void loop()
{
int data_len=0;
while(1)
{
while(Serial.available())
{
rcv_buf[(data_len++)%10] =Serial.read();
}
if(rcv_buf[data_len-2]== '\r' && rcv_buf[data_len-1]=='\n') // Stop reading the serial once getting the ending command.
break;
}
if ((data_len==4)&&(!strncmp(rcv_buf,"ON",2))) // Open the light L when the command is "ON".
{
digitalWrite(led, HIGH); // Set D13 pin as high and openg the light L
Serial.println("LIHGT ON");
}else if((data_len==5)&&(!strncmp(rcv_buf,"OFF",3))) // Close the light L when the command is "OFF".
{
digitalWrite(led, LOW); // Set D13 pin as low and the light L
Serial.println("LIHGT OFF");
}
}
Step 3: Connect the BLE-Link to the PC, and meanwhile open the RoMeo BLE. Wait a few seconds the two bluetooth devices will automatically connect. The LINK light will be on showing connection, indicating that the two devices are ready for wireless communication. Then open the serial debugging assistant and send "ON" under the mode of New line. This command is sent from the serial port, passing through the BLE-Link to RoMeo BLE. RoMeo BLE after receiving the command will parse the Arduino program, and then open the light L. When sending OFF under the mode of New line, RoMeo BLE turns OFF the light L.
