Thanks for the reply Amanda. The walkthrough that I performed before is perfectly aligned with the post you recommended. Checking this I started looking for other possible solutions.

Apparently everything was ok with my application, and my problem was related to the Iphone cache, after restarting the phone I got the expected results.

Anyone who is getting results similar to mine, even using the buttonless_dfu template in the examples, and using nRF Connect with IOS, I recommend trying to clear the iPhone's Bluetooth cache.

Taking advantage of the topic, is it possible to change the default value to be sent (0x01) so that the device enters DFU mode? I would like to send some other code to be defined internally. If so, do you have any examples of how I can do this?

Hi,

You can try the example I made in this post. It is the ble_app_uart example added with buttonless_dfu.

Regards,
Amanda

I tried to use the solution described in the link below, but without success, I still don't have DFU service, enabling DFU just by pressing the button and taking it to bootloader mode.
