Danke für eure Hilfe aber leider bin ich noch nicht zum gewünschten ziel gekommen. Ich bin mit programmieren leider noch nicht so vertraut.
@sschultewolter baud hab ich auf 9600 reduziert und bei den bluetooth modulen mit AT+UART=9600,0,0 gesetzt.
@serenifly
Ich habe mich dazu entschlossen es mit deiner String variante zu versuchen aber iwas mach ich falsch.
im serial monitor kommt immer nur:
00
0
0
0
0
0
,0
0
0
0
0
0
Wenn ich deinen teil auskommentiere und nur mehr: if (BTSerial.available()) {
Serial.write(BTSerial.read()); verwende bekomme ich das über den serial.
Wo jetzt aufeinmal die letzen Zahlen(44787) herkommen weis ich auch nicht.
0,0,0,0,48,44787,
0,0,0,0,48,45287,
0,0,0,0,48,45787,
0,0,0,0,48,46287,
0,0,0,0,48,46787,

// This example code was used to successfully communicate with 15 ultrasonic sensors. You can adjust
// the number of sensors in your project by changing SONAR_NUM and the number of NewPing objects in the
// "sonar" array. You also need to change the pins for each sensor for the NewPing objects. Each sensor
// is pinged at 33ms intervals. So, one cycle of all sensors takes 495ms (33 * 15 = 495ms). The results
// are sent to the "oneSensorCycle" function which currently just displays the distance data. Your project
// would normally process the sensor results in this function (for example, decide if a robot needs to
// turn and call the turn function). Keep in mind this example is event-driven. Your complete sketch needs
// to be written so there's no "delay" commands and the loop() cycles at faster than a 33ms rate. If other
// processes take longer than 33ms, you'll need to increase PING_INTERVAL so it doesn't get behind.

Vielleicht könnt ihr mir anhamd davon sagen wo das Problem liegt. Ich bin echt ratlos, aber kann ja nur besser werden =)
Danke.
