DFU

[dvir]

hi, I'm working with NRF52832, DFU service is configured as secured. my question is : i'm trying to change dfu characteristic property to "indication" by writing to the dfu descriptor, but no "EVT_GATT_ATTRIBUTE_MODIFIED" event is received. my connection to the NRF52832 is not secured! do I need to have a secured connection to be able to write to the DFU descriptor(if the DFU is configured as secured) ? , and do i need to have a secured connection to be able to write to the DFU characteristic (uuid : 50EADA308883B89F604F15F30300C98E) if the dfu is configured as secured?

Hi,

Assuming you built the application with ble_dfu_bonded.c and not ble_dfu_unbonded.c you need to either be paired or bonded with the device before you can access the butonless DFU characteristics. I would, however, recommend you to consider the 'unbonded' variant because it's simpler. It won't affect the validation checks inside the bootlaoder.
