how to build softdevice after I modify code

[Chaw]

Hi，Nordic I am working for BLE_DFU, on SDK 12.1 and SoftDevice s132.

I checked, I should add below code in ble_dfu.c

char_md.char_props.write = 1;

Then I added, when I use Keil to build, it only generate app hex.

How can I build softdevice?

If I choose flash_s132_nrf_3.0.0.softdevice, it show so many strage errors (can not open source input file, but if build app, same code, it show success)

Hi,

You cannot build the softdevice. The softdevice is provided as a prebuilt hex-file with an API specified in the documentation.

The S132 softdevice is located in the components/softdevice/s132/hex directory of the SDK, or can be downloaded from here.

If you tried building the softdevice in Keil using the target flash_s132_nrf52_3.0.0_softdevice, the hex file in the SDK might have been removed. You then have to download and copy the hex file into the directory specified above. There are multiple methods of programming the softdevice to the board. You can also use nrfjprog, as described in section Setting up the example of the Getting started with the nRF5 development kit tutorial.

Best regards,

Jørgen
