DFU over nRF Connect ios error "SD version check failed"

[Sreeju]

Hello,

I am using nrf Connect app from ios (iphone8) as the DFU server. The signed app is created as below:

nrfutil pkg generate --hw-version 52 --application-version 1 --application ble_app_blinky_pca10056_s140.hex --sd-req 0XB8 --key-file private.pem secure_ble_blinky402.zip

while scanning "DfuTarg" is detected and on trying to upgrade the firmware I get error message "SD version check failed".

I also tried to create the zip file with "--sd-id 1" but results are same.

Please advice..

Thanks,

Sreeju

Hi,

Since your upgrade package does not contain the SoftDevice, the SoftDevice already on the device will be used. However, this must be the correct version (which the application is built to use), which is why the ID is checked. To make this work, you have to specify the correct ID of the SoftDevice. You can get the ID of most SoftDevices using nrfutil ("nrfutil pkg generate --help"), as shown below. Then you just pick the ID that is correct in your case and use that with --sd-id when you build the upgrade image.

  --sd-req TEXT                   The SoftDevice requirements. A comma-
                                  separated list of SoftDevice firmware IDs (1
                                  or more) of which one must be present on the
                                  target device. Each item on the list must be
                                  a two- or four-digit hex number prefixed
                                  with "0x" (e.g. "0x12", "0x1234").

Thanks for the response.

I was using the wrong "--req-id" - now I see a different error "Operation not Permitted". 

[Sreeju]

The second time, I tried its 100% complete. Thanks again.

How did you select the version?

Hi,

Plase make a new question and explain in detail what you need help with.
