Hi,

The name the you see in nRF Master Control Panel is the name that should be in the mobile application.

I have also uncovered an error in a the libs/evothings/arduinoble/arduinoble.js library. The function writeDataArray should be updated to the following implementation:

device.writeDataArray = function(uint8array, uuid)
{
uuid = uuid || '713d0003-503e-4c75-ba94-3148f18d941e';
device.writeCharacteristic(
uuid,
uint8array,
function()
{
console.log('writeCharacteristic success');
},
function(errorCode)
{
console.log('writeCharacteristic error: ' + errorCode);
});
};

Try that and let me know if that works for you. I am working with Evothings to push an update of the library to their repositories.
