Hello,
We have a Xamarin Forms application, which we use for connecting to a nordic device- nrf52840 and read/write characteristics. We managed to do it using Plugin.BLE nuget available for Xamarin forms.
Our application also has an option to perform DFU. Again we using a xamarin nuget - Xamarin.Nordic.DFU.Android. Once the firmware is updated, it shows the success message and gets disconnected from the device which is correct.
Problem is once the DFU is complete, our app doesn’t connect again.. we need to open nrfConnect mobile app and read one of the attribute.. Once we read any one characteristics from the nrfConnect application, even our application starts working.
Not sure what the nrfConnect app is doing which we have missed out. We need to know what events nfrConnect is triggering and what we are missing .
Any help is highly appreciated.
Thanks & Regards,
Geervani
