A small update
First, thanks @ Admin for the quick answer.
Concerning the phone, well I swapped the sim cards, and it didn't work, so sadly I unchecked the checkbox "rSAP active" in your app, and rebooted, and now it works....
I cannot explain how, I just see sometimes a small popup from the root app that indicates that the rsap app have been granted superadmin privileges (even if I don't see the icon of the rSAP app at the top right of the phone screen ).
On my VW Golf mk 6 (RNS 510 with premium Bluetooth module) I can see in the menu that I have now the capacity of :
- making hotspot wifi wifi (Tested and working).
- SMS reading (Tested and working).
- receiving a second call (Tested and working) and even have a third but directly on the phone via SIM2.
And the phone indicate that there is no presence of SIM card in slot 1 ( normal as the sim1 is used by the car).
The problem that I had was when I turn off the car, the phone asked me for the pin code of the SIM1, sadly your plugin didn't solve the problem, the workaround that I found was to disable the PIN code check.
But now ironically my phone have battery issue and phone reboot in a loop until connect to a power supply, but it's not related with your app ( lots of users of this Archos 50 Diamond reported the same issue) and of course the battery isn't removable.
