Hi, That is the first time I use this mailing list, so tell me if I'm doing anything wrong when using it. Thanks !
Now my problem. I'm developing a Qt application that communicates with a BLE device. It worked perfectly until I tried to add some security. When I turned on "Just Works" security mode (device side), I was not able anymore to write in a characteristic (or read) from my Qt application. I compared the Bluetooth messages sent from Qt app and from the android app *nfr Connect* and I see that automatically, the *nrf Connect* app sends a bonding request when it fails to write. Qt does not do this. That is the only difference that makes the android app working but not my Qt app. I finally made it work once : I start my Qt App, pair my BLE device with *Windows parameters* and then it works *one time *only (after that I need to unpair my device from Windows parameters and redo the same process). It only works if it has been paired with Windows parameters... I could not find anything about bonding in the API or security mode settings. Any idea ? Should I post it as a bug or am I missing something ? Thanks, Regards, Simon Feutrier
