Android Question DJI binding process

Hi all,
I'm still fighting with my connection problem to the DJI SDK
It systematically falls into an UNBOUND state and I found it fails just when the HOME is found.
Just before it is UNBOUND the state it gets is "NOT REQUIRED" and it remains in "NOT REQUIRED" until the GPS has fixed.
Flying in UNBOUND is possible but the drone is limited in range (~30m)

So I tried to switch off the data just before the GPS is fixed and it seems to work fine.
I wanted to switch into Plane OFF mode but this seems being impossible with most recent ANDROID.

Hence my question, is there a way to block the connection to DJI servers by software or to kill something to forbid it goes on trying to connect when the "NOT REQUIRED" state is reached ?
