App nRF connect for mobile (IOS) does not stop DFU when nordic BLE device reply error

[Thibaud]

Hello

I am developpping a BLE device updatable over the air with a nRF52840 chip.

Seems my device is working on battery I am not always allowing DFU. 

I am doing the ota DFU with the nRF Connect for mobile application, on IOS and when I disallowe the DFU the application does not stop trying.

It is a bit disturbing because when we use the applciation we cannot differentiate whether the update will start or not.

Best Regards

Hello,

How do you reject DFU requests in your application, do you ignore the request, or do you send a response code to the client?

Thanks,

Hello

I decline it with mcumgr error code. I tried MGMT_ERR_EBADSTATE & MGMT_ERR_EACCESSDENIED.

Hello,

Thanks for confirming. I discussed this with the team, and they're ready to work on a fix. Do you happen to have a minimal version of your project that rejects DFU requests that we can use to test against? Alternatively, just relevant code snippets that I can copy it into sample application.

Best regards,

Vidar

Hello

Here is all my "dfu functions" and a kconfig overlay.

Do not forget to delete all my custom includes in DFU.c

Hello 

Sorry here is an updated version where I deleted all my custom part.

You should be able to just add this to a hello_world sample and build.

DFU_v1.1.zip
