9dof razor and BLE mini #11
Description
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:
- https://github.com/ptrbrtz/razor-9dof-ahrs/tree/master/Arduino/Razor_AHRS
- https://github.com/RedBearLab/iOS/tree/master/Examples/BLEChat_Central_OSX
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!
