Hi
Oh, I'd like to clarify something. I want to use S332's ANT+BLE in application, and I also want to perform DFU upgrade via Nordic BLE.

I see. Then you need to use the S332 header files that you get from Garmin (it is part of the S332 distribution).

Hi 
I transformed the pca10040_s132_ble example in the secure_bootloader into the s332 version. Then generate the corresponding bootloader.hex and combine it with ANT_S332_NRF52832_6.1.1.HEX, setting.hex and application.hex to burn them into the nrf52832. However, it seems to not work. I saw this log through rtt. Could you please tell me how to modify it to make it work?

Hi,

It looks from the log that an APP_ERROR_CHECK is called with an error code in the bootloader. Can you build the bootloader with DEBUG defined? Alternatively, set a app_error_fault_handler () breakpoing in components/libraries/util/app_error_weak.c and check the callstack to see where the error occured. When we know where, and with which status code, that will tell us more about what the problem is and how it can be resolved.
