This might be more an Android programming question than PSoC but if anyone has experience with FLOAT data:
Using a characteristic with Field, New Field, Type FLOAT, Length 4.
As suggested here, the float is cast (void) on writing in PSoC:
notificationHandle.value.val = (void *)&Ah;
In Android, reading it with float c = getFloatValue(BluetoothGattCharacteristic.FORMAT_FLOAT, 0);
only gets INFINITY. The data is being transmitted, because if I get it as 4 bytes and convert to IEEE 32 bit float, it's correct (that was a two aspirin coding job for me;)
03-25 19:11:43.158: D/BluetoothGattActivity(6732): AH Got 229,242,63,63
in hex those are: E5 F2 3F 3F
AH should be around 0.752
The above converts to: 0.749800026417
