If you change the UUID of the DFU service, then the nRF Connect app will no longer recognize it as a DFU service.

It is not a problem to do so in itself, but you need to create your own (mobile) application to look for the service with the new UUID, and then treat it as a DFU service.

Thank you for your reply.

I find the problem.I want the DFU service to look intuitive in NRF Connect APP. So, i charge the BLE_DFU_SERVICE_UUID. I even use 128-bit UUID. It makes the service abnormal.

Hello,

[quote user=""]I click the DFU control point and load OTA package for Remote Upgrade. But it failed. I find it doesn't seem to be in bootloader.[/quote]

So what does it say? Does it say "invalid image" or another return error?

What image do you try to use for the update? Is it signed with the correct key?

If you haven't seen it, then I suggest you check out this guide.

Best regards,
