Hallo,
ich habe zwei von diesen Grove Bluetooth Modulen
http://www.seeedstudio.com/wiki/Grove_-_Serial_Bluetooth
Ich habe Sie am Arduino Mega (Pin 19 und Pin 18, spirch UART) und am Uno (Pin 6/7) angebunden.
Laut LED Status sind auch beide im Modus des "Paring". Aber Sie verbinden sich nicht.
Ich nutze für den Master folgenden Code

Den Slave kann ich auch mit dem Handy suchen und verbinden. Allerdings wechselt auch dann die LED Anzeige nicht.
Habe ich evtl einen Pin Fehler?
Uno:
- Pin 6 Hardware = RX,
- Pin 7 Hareware = TX
Merga_
Pin 19 auf TX
Pin 18 auf RX
Ich habe im Code die Pins gedreht. Seit dem hat erzumindest den Zustand des Kopplungsversuches. Aber koppeln tut er nicht. Kann es an dem Umstand liegen, dass ich auf den UART Port ein Software Serial anwende?
