Recently we upgraded from NRF52832 to NRF52840, and as the Development seems to come to an end, one of the last features we need is OTA capability.
currently I am trying to Implement DFU on my application, but I am struggeling.
I downloaded the latest SDK and tried to compile \examples\dfu\secure_bootloader\pca10056_ble project.
after compiling I flashed softdevice (make Flash_Softdevice) and then flashed the bootlader (make Flash) but my board wont advertise.
next step was to try one of the precompiled examples, I successfuly flashed sd_s140_bootloader_buttonless_with_setting_page_dfu_secure_ble_debug_without_bonds.hex, and it worked! I could see the DFUtarg advertising, then I tried to flash the softdevice and bootloader_secure_ble_debug_without_bonds_s140.hex seperately, and again, it did not advertise.
what am I doing wrong?
thanks in advance,
