--sd-req for the latest version of the 132 SoftDevice

[Aleksa]

Hi,

I am currently working on buttonless DFU for my application and I encountered a problem when I generated the .zip file. 

In this line

nrfutil pkg generate --application app.hex --application-version 1 --application-version-string "1.0.0" --hw-version 52 --sd-req 0xA8 --key-file private.pem FW.zip

--sd-req, in this case, is for version 6.0.0 and I have built my application using the latest version of SoftDevice s132 which is 7.2.0. Now what I have tried is to run the command

nrfutil pkg generate --help

but unfortunately, there is no listing for the current version. Here is the list I am getting

I have verified that I have successfully merged the buttonless example with my app because everything works if I flash older SoftDevice and set the correct code which I think is not the correct way to process. If I flash my current SoftDevice but leave the old code, the bootloader simply refuses to update the app.

My question is where can I find the info about the latest version of SoftDevice that I need to use?

Thanks

The code is in the release notes documentation for the specific SD version (a pdf).

Yes, The Firmware ID of this SoftDevice is 0x0101. See the s132_nrf52_7.2.0_release-notes.pdf under nRF5_SDK_17.0.2\components\softdevice\s132\doc.

Thank you, that fixed my problem and now everything works as expected.

Follow up question.
I am using nrfutil version 6.1.1 and when I use SoftDevice S132 v7.2 I use the version required value of 0x0101. However, the DFU over BLE process aborts with an error "SD_VERSION failure".

The same setup (same bootloader + settings + application_using_s132_v7.0.1) works fine if I try the DFU over BLE but link my application to SoftDevice version 7.0.1 which uses the command line option --sd-required=0xCB.

Is this a bug in the Soft Device or in the nrf_util or something else?
