compile error of DFU with nRF52832

[edmond.yun]

Hello,

I am using 14.0.1 sdk, and hope to use DFU (Secure bootloader), I am trying to use buttonless app in my app (uart example app), when copying some codes related with DFU function as follows, I have one error : Fatal Error[Pe1696]: cannot open source file "nrf_dfu_svci.h" C:\working_dir\yps-202n\nRF5_SDK_14.1.0_1dda907\components\ble\ble_services\ble_dfu\ble_dfu_bonded.c 45

I tried to add some codes in compiler as follows, but the error is happened. please help to let me know what I should do in order to solve this issue,

: add ble_dfu.c , ble_dfu_bonded.c and ble_dfu_unbonded.c in nRF_DFU folder, add nrf_dfu_svci.h in nRF_SVC folder,

thankful for your support in advance,

thanks.

Hi edmond.yun, I want to make sure I understand your question correctly. Are you trying to update the uart example application located in the folder examples\peripheral\uart with the buttonless dfu bootloader located in the folder examples\ble_peripheral\ble_app_buttonless_dfu in sdk 14.1? If so, have you taken a look at the buttonless dfu section in the secure dfu bootloader blog post. If this is the first time you have tried to do a dfu, I would recommend going through the blog post first with a simple example (like the blinky example located at examples\ble_peripheral\ble_app_blinky). Then, I would try the buttonless dfu application.

Hi edmond.yun, I took a look at the other devzone case you mentioned. Seems like you got everything working, right?

Hi, Bjorn, you are right, It seems to be successful, because when updating package file with app, it is no problem to update the pak file and to reboot system with new app, I can see new log in terminal,

but I wonder NRF_SDH_BLE_VS_UUID_COUNT, what is it, and why need to increase the value ? and what is standard to increase it ? Could you please kindly provide me more information ?

thankful for your concern and kindness in advance,

thanks.

The NRF_SDH_BLE_VS_UUID_COUNT macro defines the number of vendor-specific UUIDs. If I were you, I would take a look at the services tutorial to get a better understanding of custom services & characteristics. Basically, for every custom service & characteristic, you need to define a custom 128-bit UUID, also called the vendor specific UUID. So figure out how many custom services & characteristics you are defining & set NRF_SDH_BLE_VS_UUID_COUNT to the number of custom services & characteristics. What is the minimum value you can set NRF_SDH_BLE_VS_UUID_COUNT to make the DFU work without any errors?
