nRF52 error during DFU process

[Mehdi]

Hi, 

I'm developing an nRF52 application based on SDK14 and S132 that require the DFU service.

The DFU is not performed using the nRF toolbox application on both of android and iOS with a different error message.

I got one of the error messages below: 

• Enabling Indication failed : Under iOS_V10.3.2.
• DFU device not bonded   : Under Android_V6.0.1.

When I tested with the DFU_Buttonless example from SDK14 the DFU performed correctly under Android.

Best Regards,

Mehdi.

Hi Einar,

Thank you for your quick reply and for the advice.

I have another question please, now i'm using DFU without bonds, I changed the private key in my '.pem' file and i generated another application package '.ZIP' in order to test the security of our DFU.

When i tested DFU with the modified private key, this operation still proceed.

Is this the normal behavior ? 

Best Regards,

Mehdi.
