Hi All,
I was succesfully developing an application for the mavic mini. It was working fine up to today when the mini denies to connect to the SDK.
I tried again with the simple drone application provided by Erel, same result
I tried to kill my DJI account including all the app keys, then I created a new account with a new email address, registered the applications under new names but the problem remains the same: impossible to connect the aircraft.

here is an extract of the filtered log, the detailled one is attached in a file
**************************** BaseApplication2 **************************
*** Service (starter) Create ***
** Service (starter) Start **
** Activity (main) Create, isFirst = true **

*** Service (remote) Create ***
** Service (remote) Start **
Activation state changed: ACTIVATED
SDK_BindingStateChanged: UNKNOWN

SDK_BindingStateChanged: UNBOUND
Aircraft disconnected!

I must admit I'm stuck...
Any help welcome ! Thanks

Thank you Erel.
Unfortunately I get the DJI Fly app and I'm logged in.
Litchi works fine too.

I uninstalled DJI fly and donwloaded it from DJI servers. I performed the installation and logging but the result is the same.

I found a workaround to allow playing with the SDK despite the "not connected status": just removing the UItimer stop...

Sub SDK_BindingStateChanged (State As String)
    Log($"SDK_BindingStateChanged: ${State}"$)
    If (State = "BOUND" Or State = "NOT_REQUIRED") And aircraft <> Null And aircraft.Connected Then
        Log("Aircraft disconnected!")
        lblText.Text = $"Disconnected!!!"$
    '    UItimer.Enabled = False
    End If
End Sub

Or (more seriously) your app being spread, you are no longer eligible to the free plan :

Free plan limit is : Up to 20 mobile app activations

What does it means exactly ? Your App activated on more than 20 drones ?

Edit : seems to be your app activated on 20 different mobile phones :
Well, it could be that indeed.
My app was given for test to some friends on a forum, then the problem occured on the simulator...
I think I fried my DJI free license !

premium is only for the "support" and it is a "one time ticket"

It has to be added to the 99$ professional tier (annual fee)
