In this case, for me, that's not an idle connexion. I consider an idle connexion as a connexion which is not used by any programs running on the device. If your device checks emails, you do not have to close the connexion.

Maybe in the end we're just using a different definition for the term "idle".

I totally agree with you. Of course there will be a lot more RX than TX packets. But you will have several TX packets and then, enough to detect that the connexion is active and used.

What are your 2k per minute used for ? Emails ? Weather update ? Then again we are not using the different definition of the term 'idle'.

Anyway that's interesting because we have both different needs and it has to be taken in account to make a generic app for that.

Thanks again for your feedback!
