BLE DFU Extension Issue

[Siva]

Hi,

I have added "DFU" functionality to my existing BLE application Test.rar.

"I am using nrf52 SDK v11.0".

I have programmed the device with softdevices (S132.hex) and application and it doesn't work. I am sure I have something wrong but don't know where....

At line 991 in the main.c where I have defined "reset_prepare" function to enter dfu mode.

Also, do I have to load bootloader file? If so where can I find "Bootloader.hex"?

If I am using bootloader do I still have to load softdevices?

It would be great if anyone can advise on this.

Regards Siva

Hi Siva, I recommend that you use the ble_app_hrs example with DFU support as a reference when adding DFU to you own application. You can find it in the following folder in the nRF5_SDK_v11_0_0\examples\ble_peripheral\ble_app_hrs\pca10040\s132_with_dfu\arm5_no_packs
