Hi, möchte Daten die ich von einem Fio aus via XBEE S2 an dem Arduino UNO(inkl. Wireless SD Shield+XBEES2) sende mit Bluetooth anhand von dem Bluefruit LE SPI an das Smartphone senden.
Nun habe ich dieses an den Arduino Uno geflasht und war mir ziemlich sicher, dass ich damit die empfangenen Daten via XBEE direkt über dem Bluetooth-Modul an das Smartphone senden konnte, doch sobald ich mich anhanf der Bleufruit LE APP mit dem Modul verbinde und auf Uart gehe kommt nichts an.
Habe alles Versucht und mehrmals mir das Tutorial angeschaut, doch jetzt bin ich an einem Punkt, wo ich nicht mehr weiterkomme.
Hier der Code:
include <Arduino.h>
#include <SPI.h>
#if not defined (_VARIANT_ARDUINO_DUE_X_) && not defined (_VARIANT_ARDUINO_ZERO_)
#include <SoftwareSerial.h>
#endif
#include "Adafruit_BLE.h"
#include "Adafruit_BluefruitLE_SPI.h"
#include "Adafruit_BluefruitLE_UART.h"
#include "BluefruitConfig.h"
/*------------------------Global variables-----------------------------*/
String receivedData="";
boolean stringComplete= false; //Flag if string is completely received
/*---------------------------------------------------------------------*/
// Create the bluefruit object, either software serial...uncomment these lines
/* ...or hardware serial, which does not need the RTS/CTS pins. Uncomment this line */
Adafruit_BluefruitLE_UART ble(BLUEFRUIT_HWSERIAL_NAME, BLUEFRUIT_UART_MODE_PIN);
/**************************************************************************/

automatically on startup)
*/
/**************************************************************************/
void setup(void)
{
// put your setup code here, to run once:
//Baudrate für XBEE-KOmmuikation & Bluetooth Module
Serial.begin(9600);
pinMode(13,OUTPUT); //Pin 13= integrated LED of Fio
//reserve 200 bytes for receivedString
receivedData.reserve(200);
/* Wait for connection */
while (! ble.isConnected())
{
delay(500);
}
// Set module to DATA mode
Serial.println( F("Switching to DATA mode!") );
ble.setMode(BLUEFRUIT_MODE_DATA);
}//end fu
void loop(void)
{
// put your main code here, to run repeatedly:
serialEvent();
if(stringComplete == true)
{
//send characters to Bluefruit module --> everything that comes on RX-Pin will reach Bluetooth module
// Send characters to Bluefruit
Serial.print("[Send] ");
Serial.println(receivedData);
ble.print("AT+BLEUARTTX=");
ble.println(receivedData);
//clear stringbuffer
receivedData="";
stringComplete=false; //reset flag again to false
}//endif
}//end loop
void serialEvent()
{
while(Serial.available())
{
char inSign=(char)Serial.read();
//add the read sign to the buffer & increment counter of buffer
receivedData+=inSign;
//when incoming character is "/n" set flag --> /n = sign that string ends
if(inSign == '\n')
{
stringComplete=true; //flag = true
}//endif
}//end while
}//end fu
Bitte um eine Hilfestellung bzw. kann mir jemand helfen?
Danke sehr
Anbei noch die Config Datei für die Pinbelegung via SPI.

ein einfacheres BT Modul hätte es nicht getan?
Bevor ich überhaupt mit Code anfangen würde, würde ich erstmal versuchen ob ich mich mit dem Smartphone überhaupt verbinden kann. Irgendweche Status LEDs wird es dazu auf dem BT Modul sicherlich geben. Vielleicht mußte es auch erst noch konfigurieren. Baudraten o.ä.
Desweiteren muß Pin 10 (53 beim Mega) auf Ausgang definiert sein. Egal ob benutzt oder nicht. Sonst funktioniert SPI nicht.
