SoftDevice and Application firmware upgrade from 6.1.1 to 7.2.0 issue

[Yuriy Sharamaha]

I am trying to upgrade SoftDevice and Application firmware from v6.1.1 to v7.2.0 on Nordic USB840M dongle and I am facing a strange issue after such upgrade.

Please find below the steps I am doing:

1. Generate the upgrade zip package: 
2. nrfutil pkg generate --hw-version 52 --sd-req 0xB6 --sd-id 0x100 --softdevice ".\s140_nrf52_7.2.0_softdevice.hex" --application-version 1 --application ".\connectivity_4.1.1_usb_for_s140_7.2.0.hex" --key-file ".\private.pem" ".\sd_app_6.1.1_to_7.2.0.zip"
   Zip created at .\sd_app_6.1.1_to_7.2.0.zip
3. Program the dongle: 
4. NrfUtil.exe dfu usb-serial -pkg ".\sd_app_6.1.1_to_7.2.0.zip" -p COM7
     [####################################]  100%
   Device programmed.

After such upgrade the device appears in the device manager as USB Serial Device (COM8) with VID_1915&PID_521B and with the pretty old driver installed:

Then I've performed the downgrade of SoftDevice from 7.2.0 to 6.1.1. Please find below the steps I am doing:

1. Generate the downgrade zip package: 
2. nrfutil pkg generate --hw-version 52 --sd-req 0x100 --sd-id 0xB6 --softdevice ".\s140_nrf52_6.1.1_softdevice.hex" --application-version 1 --application ".\connectivity_4.1.1_usb_for_s140_6.1.1.hex" --key-file ".\private.pem" ".\sd_app_7.2.0_to_6.1.1.zip"
   Zip created at .\sd_app_7.2.0_to_6.1.1.zip
3. Program the dongle:
4. NrfUtil.exe dfu usb-serial -pkg ".\sd_app_7.2.0_to_6.1.1.zip" -p COM7
     [####################################]  100%
   Device programmed.
   

After such downgrade the device appears in the device manager as nRF Connect USB CDC ACM (COM6) with VID_1915&PID_C00A and with the new driver installed:

I have attached the SoftDevice and Application firmware hex files:

4377.connectivity_4.1.1_usb_for_s140_7.2.0.hex

I have installed nRF Connect for Desktop 3.10.0

Any help or insights are much appreciated.

I have applied the patch nRF5_SDK_15.3.0_connectivity.patch to nRF5_SDK_15.3.0, but I did not apply it to nRF5_SDK_17.1.0. Is there any similar patch for nRF5_SDK_17.1.0? Or can I apply nRF5_SDK_15.3.0_connectivity.patch to nRF5_SDK_17.1.0?

No, there is no similar patch for 17.1.0 and you cannot apply the 15.3.0 patch to 17.1.0. SDK 15.3.0 is the latest that is (and will be) supported.

[Yuriy Sharamaha]

Understood, thank you!

Is there any way to use SoftDevice v7.2.0 with the connectivity application of v6.1.1? For example, generate the upgrade zip package with SD v7.2.0 and the connectivity app of v6.1.1 and then program the dongle by nrfutil. I need SD v7.2.0 because it supports the BLE_GATTC_OPT_UUID_DISC option.

[Einar Thorsrud]

There is always a way, provided you are willing to do the effort. There are API changes between major versions of the SoftDevice, so some porting will have to be involved. I suspect the easiest is to stick with SDK 15.3 and the patch form the from pc-ble-driver repo, and use that as a starting point. Then port that to SoftDevice 7.2.0 first and get that working. Then add BLE_GATTC_OPT_UUID_DISC to the serialization code on the nRF and the pc-ble-driver. I cannot say exactly how much effort this will take, though.

An alternative could perhaps be to consider if you can achieve your end goal differently, without using BLE_GATTC_OPT_UUID_DISC.

Hi Einar,

this is what I was originally doing - I was adding the serialization code for BLE_GATTC_OPT_UUID_DISC option to nRF SDK 15.3.0 and pc-ble-driver. Then in my client application I was attempting to call sd_ble_opt_set(adapter, BLE_GATTC_OPT_UUID_DISC, &uuid_opt), but it was failing with the error 0x8001 NRF_ERROR_SD_RPC_ENCODE. I've made an assumption that it fails because I was still using SoftDevice 6.1.1 which does not have BLE_GATTC_OPT_UUID_DISC option.

So, now my main question (and challenge) is how to port nRF SDK 15.3.0 to SoftDevice 7.2.0. I would appreciate any help or insights on this.

I suggest you refer to the migration document for 7.2.0. This is part of the zip distribution of the SoftDevice. That contains the API changes for the SoftDevice, and you need to follow that back to 6.1.1 and accommodate for any changes to SDK code that is being used.
