Hi guys,

I'm trying to transmit data from the 9dof Razor IMU module (from Sparkfun) via the BLE mini (Red Bear labs) to the BLEChat_Central_OSX app and it doesn't work :/

The codes I use are:

I tried to transmit via BLE only one value with following code:

     Serial.print(int(smoothedAX));

     Serial.println();

But when running the BLEChat on Xcode I receive only "i" and "Y" values:

I also tried to transmit the data with an adaption of the arduino code:

     // uint16_t value = smoothedAX;

     uint16_t value = 123; // fake reading

     BLEMini_write(0x0B);

     BLEMini_write(value >> 8);

     BLEMini_write(value);

But then I receive an error message instantly:

I tried to look for a solution for three days but I haven't been able to solve the problem. It would be really nice if you could help me :)

Thanks a lot in advance and cheers!
