Activate free sensor with mobile application

Hello,

I am using free since January.I am delighted with him.I just learned that you can measure with the mobile too.I have downloaded the application on the mobile, and the values ​​are identical to those of the meter.

My question is: When the sensor expires, the new sensor can be activated with the application of the mobile or it is necessary to activate it with the original meter ??

Thank you!!

@"Lokkus78" If you activate the sensor with the application of the mobile "only" you will be able to use the sensor with the phone but not with the reader.To use the 2 systems you have to activate with the reader and in the 1st hour you activate it with the mobile.-
