Implementing DFU with softdevice s332

[Cintia]

Hello,

I'm working on a s332 application and I need to include the DFU feature in the code. I've managed to perform a DFU on s132 applications following examples like this <novelbits.io/.../>, but I'm having trouble with s332 because I believe it needs to change the memory size (maybe more stuff?). Can someone show me an example of how to implement DFU on a s332 application? Thanks in advance.

Hi, 

I'm having trouble with s332 because I believe it needs to change the memory size (maybe more stuff?).

You can refer to the  Adjustment of RAM and Flash memory to adjust the Flash and Rom address for s332.  You also can refer to the Flash and Rom address setting for s332 in \ble_app_hrs\pca10040\s332 project. 

Can someone show me an example of how to implement DFU on a s332 application?

I think you can use the s132 example to replace SD with s332. The flow is the same, only the SD is different.

Amanda

You mean the ble_app_buttonless_dfu s132 and replace the SD with s332? Or do you mean some other example? Because I couldn't find anything about DFU on the hrs example.

Yes, the 2 main steps are to update the linker settings and change the softdevice including paths to point to the s332 headers.
