Hello,
We do not have any React Native library for the nRF Connect Device Manager libraries. The one you tried to use, Nordic DFU, was made by somebody else and we're just referring to it on our repo.
If you'll implement such library, and want to make it public and open source, we'll gladly point to it from our repos.

Hello,

You're using Files tab, instead of Image tab. Files tab is to send and download files to a file system on the device, not to update it. Please, use Image tab. There, you'll have 2 modes: Basic and Advanced.

In Basic mode (visible by default) you may select the bin file and upload it. The upload should work.

ZIP files are for updating multi-code devices, like nRF5340, which need one bin file per core.

Hi Neel,

I am checking internally if there is React Native library available.

But as far as I know the only available code we have for nRF Connect DFU is the nRF Connect Device Manager app , so you may want to consider study the code of the app.

Hi Hung,

Please let us know if any library is available for React Native which can work with nRF Connect SDK DFU operation.

Thanks!

Hi Neel,

Please be aware that the .zip that the library in React Native is build for a different DFU protocol. It's the nRF5 SDK DFU protocol not the nRF Connect SDK protocol.

So if you plan to support the nRF Connect SDK DFU you would need to write the new app based on the Device Manager app that we provided.

The old React Native app won't be able to do DFU update to a nRF Connect SDK application.

Hi Hung,

Thank you for your quick response. I am good that you can reproduce the issue.

This issue is only with the dfu_application.zip package. There is no issue with the app_update.bin file in the Android or iOS nRF Connect application.

As I have earlier informed you that we are also developing a custom mobile application based on React Native. It only supports the ZIP package to perform the DFU operation.

Thanks!

Hi Neel,

I have just tested on an iPhone and can see the same error that you are seeing. I will check with the team to see why that happened.

Could you try to test with nRF Connect app and the app_update.bin file ? I found that it worked for me on an iPhone.
Is there any reason you need to use the .zip file instead of the .bin file ?

Hi Hung,

I have tried to perform DFU using the given dfu_application.zip file using the iOS nRF Connect application, but it throws me the same error message.

Could you please try to perform it on an iphone?

Thanks!

Hi Hung,

Let me give you brief information regarding the process I am following to perform the DFU operation in V2.0.0.

I am using the "zephyr/samples/bluetooth/peripheral" example to test the DFU. I have made changes in prj.conf file as mentioned in this document Add DFU support to your application.

CONFIG_BT_KEYS_OVERWRITE_OLDEST=y
CONFIG_BT_SETTINGS=y
CONFIG_FLASH=y
CONFIG_FLASH_PAGE_LAYOUT=y
CONFIG_FLASH_MAP=y
CONFIG_NVS=y
CONFIG_SETTINGS=y

# Enable mcumgr.
CONFIG_MCUMGR=y

# Enable most core commands.
CONFIG_MCUMGR_CMD_IMG_MGMT=y
CONFIG_MCUMGR_CMD_OS_MGMT=y

# Ensure an MCUboot-compatible binary is generated.
CONFIG_BOOTLOADER_MCUBOOT=y

# Allow for large Bluetooth data packets.
CONFIG_BT_L2CAP_TX_MTU=252
CONFIG_BT_BUF_ACL_RX_SIZE=256

# Enable the Bluetooth (unauthenticated) and shell mcumgr transports.
CONFIG_MCUMGR_SMP_BT=y
CONFIG_MCUMGR_SMP_BT_AUTHEN=n

# Some command handlers require a large stack.
CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE=4096

I have created a new dfu.c file for SMP Bluetooth Registration.

#include <init.h>

#include <img_mgmt/img_mgmt.h>
#include <os_mgmt/os_mgmt.h>
#include <mgmt/mcumgr/smp_bt.h>

#include <logging/log.h>
LOG_MODULE_REGISTER(init_dfu);


static int bt_smp_init(const struct device *dev)
{
   ARG_UNUSED(dev);
   int err = 0;

   img_mgmt_register_group();
   os_mgmt_register_group();

   err = smp_bt_register();

   if (err) {
      LOG_ERR("SMP BT register failed (err: %d)", err);
   }

   return err;
}

SYS_INIT(bt_smp_init, APPLICATION, CONFIG_APPLICATION_INIT_PRIORITY);

Below are the compilation steps to generate dfu_application.zip and merged.hex files.

west build -p -b nrf52dk_nrf52832 -s zephyr/samples/bluetooth/peripheral -d test-build/peripheral

west flash -d test-build/peripheral

Now, I made some minor changes in the code to validate whether DFU is successfully completed or not. When I am trying to upload the dfu_application.zip file through the nRFConnect application on Android, it could complete the DFU and new firmware is running. But the same thing when I am trying to perform DFU with the same dfu_application.zip file, It couldn't perform and gives me the below error message.

We are also developing a custom mobile application using React Native and we're also facing the same issue. Please suggest a solution to this issue.

Thanks!

Hi Neel,

Could you provide the .zip file so we can test here ?

Could you try to test with this file:

devzone.nordicsemi.com/.../dfu_5F00_application.zip

It's created from this project :

devzone.nordicsemi.com/.../peripheral_5F00_uart_5F00_smp.zip

Hi Hung,

I am using NCS version V2.0.0.

Yes, I tried the same thing using the nRF Device Manager app and faced the same issue in iOS.

Thanks!

Hi Neel,

Could you check what inside dfu_application.zip ?
Please let us know the NCS version you are using?
Have you tried to test with the nRF Device Manager app ?

Hi Hung,

Thank you for your kind response.

Now, I installed nRF Connect SDK using the "Installing automatically" method and it could generate the dfu_application.zip file.

Now, I am facing another issue is that I could perform DFU using the Android nRF Connect application but iOS nRF Connect application raising the issue.

Please find below the error message for reference.

As per my knowledge, it tried to find the *.dat file from the ZIP package and it is not available.

Thanks!

Hi Neel,

Could you double check which SDK version you are using ? Our latest NCS SDK is v2.0.1

https://github.com/nrfconnect/sdk-nrf

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/index.html

Have you configured CONFIG_MCUBOOT=y in your prj.conf

I assume you sign the the image manually ? to get the app app_update.bin file.

I would need to check on how to generate .zip file in NCS , I usually compile using Visual Studio Code and the app_update.bin file and the dfu_application.zip file was automatically generated.

Hi Hung,

Thank you for the quick response.

As I have mentioned in my ticket, I am using nRF Connect SDK (3.0.0). When I build source code using the WEST command, the build .zip file is not available in the build directory. Please find below the command to compile the source code.

west build -b nrf52dk_nrf52832 -s test-src/peripheral/ -d test-build/peripheral -- -DCONFIG_MCUBOOT_SIGNATURE_KEY_FILE=\"bootloader/mcuboot/root-rsa-2048.pem\"

Here, test-src/peripheral/ is the source directory and test-build/peripheral is the build directory.

Please let me know if I am missing something.

Thanks!

Hi Neel,
As far as I know when you do "nrfutil pkg generate" to generate .zip file it's not for the application created with NCS but the application created with NRF5SDK and the correspondent bootloader for it is the one in nRF5SDK not MCUboot and SMP protocol.

If it's the case the app won't be able to do DFU update to the NCS application.

We do support .zip file but it's the .zip created by Zephyr in build folder, not nrfutil. Please have a look at the NRF Connect Device Manager app here here: https://github.com/NordicSemiconductor/IOS-nRF-Connect-Device-Manager/blob/master/Example/Example/Util/McuMgrPackage.swift
