[quote user=""]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.[/quote]

So that means that the DFU is complete and it starts advertising again, right? Why does your application not connect? Does it not find the BLE device? Have you tried to capture a sniffer trace to find out why the application doesn't connect?

I guess the nRF is the BLE peripheral, right?

You say that the device behaves normally after you connect to it with the nRF Connect mobile app. How is that able to connect, and not your application? Does the advertisements of the peripheral change after you connect to it with nRF Connect? If so, what?

Best regards,
