Extend BLE application to support the BLE DFU Service with nRF52832, SDK15.0.0, Softdevice S132

[Ran Ratson Kohavi]

Hello,

I'm using nRF52832, SDK15.0.0, Softdevice S132.

What should be the code added to application in order to support BLE DFU service?

I've been here, but its for nRF52 SDK V0.9.2 (which I think is very old).

Thanks in advance for your reply.

Hello,

If you have not used the bootloader and DFU yet, I suggest that you start with this guide. I know it is a bit old, but it should be very suited as a starting point for SDK15.

If you start with this example, and then move over to the ble_app_buttonless_dfu example in SDK15\examples\ble_peripheral, using the same bootloader that you made in the guide, using the SDK15\examples\dfu\secure_bootloader\pca10040_ble, you should be up and running. 

 

What you want to do, eventually, is to add the buttonless_dfu service from the ble_app_buttonless_dfu example to your custom project. Note that this requires the chip/board to have a bootloader flashed when running, or it will cause an application error. This can be ensured upgrading from the dfu\secure_bootloader example to the buttonless_dfu example using the bootloader.

 

Let me know if you run into any problems on the way.

 

Best regards,

Edvin

Hi Edvin, do we have a tutorial on how to migrate buttonless_dfu service to any existing bonding project such as  ble_app_gls?

I failed and had no clue.

Hello,

Not that I am aware of. I will be out of office for about a week, so I suggest that you create a new ticket, where you describe what the issues you encountered when trying to add the buttonless_dfu service to your project.

Best regards,

Edvin
