Hi Max,

the bootloader in SDK v12.x.0 currently only supports secure DFUs, i.e only accepts signed firmware images.

You can port the legacy bootloader from SDK v11.0.0 to SDK v12x.0.0 by compiling the bootloader project against the S132 v3.x.0 headers.

Here is the Migration Document:

s132_nrf52_3.0.0_migration-document.pdf

Best regards

where i can fined the headers? i need a normal dfu sdk 11.0.0 s132 that works for sd v3.0 thanks

The headers for the softdevices can be found in components\softdevice\s132\headers.

You have to modify the bootloader project so that all the functions with sd_-prefix is compatible with the S132 v3.0.0 headers. If you look inside the softdevice_enable() then you'll see that it call sd_-functions calls, like sd_ble_enable. Some of these calls have changed from SDK v11 to SDK v12 and you have to refer the API reference of the S132 v3.0.0 to see which modifications you have to do.
