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,

We have a BLE sensor. We would like to update FW OTA.

So now I want to see if I can update the ble_app_hrs.zip (which is created via the nrfutil tool) from the DK to our sensor (DK -> Sensor)

I hope the problem was that I used the same --sd-req 0x98 as in the blog post and not 0x00a8 for S132 V6 (as I commented here)

My DK was burned out, so I'm waiting for new board to continue the experiment.

BR,

Ran

That may be. nrfutil is not always up to date on the --sd-req hex values. 0x008a will still work, but it is not listed in the --help menu. To see what version a softdevice is, you can flash the softdevice to a DK, and open nRFgo Studio, and see the softdevice id there.

 

Also remember to update the --application-id to always be at least 1 higher than the currently running application. Unless the the bootloader will reject the packet.

 

BR,

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
