How to disable bootloader dfu signature ?

[Justin_Yeh]

Hi 

I want to update bootloader.zip file over BLE DFU mode without signature checking, the open bootloader example only for USB, 

How to disable bootloader signature checking at secure bootloader example code ? Thanks.

Hi,

It is possible to remove the signature requirement from the secure bootloader examples, but then you should not use the same Service UUID as it is reserved for the secure implementation (I.e., DFU with signature requirement). You may use the nrf_dfu_req_handler.c file from the open bootloader as reference to see how you can disable the signature check (req handling should not be transport depentent). Note that the open bootloader still require signature validation for bootloader updates.
