Exercise 3 – FOTA over Bluetooth Low Energy example inter_less8_exer3_solution not build with nrf7002dk

[ChiragBhavsar]

Hi,

I used the reference code from inter_less8_exer3_solution and successfully built it with the nrf5340dk board. However, when building it for the nrf7002dk, I encountered an error.

To resolve this, I created a child_image/mcuboot.conf file and added the following parameters. This allowed the code to build successfully, but the SMP service still wasn't generated.

CONFIG_BOOTLOADER_MCUBOOT=y

CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU=y

Hello,

It appears that the DevAcademy sample for BLE FOTA does not support the nRF7002DK out of the box. I see that my colleague has already provided you with a working sample for the nRF7002DK and explained the changes needed to make it work in this ticket.

Kind regards,
Abhijith

Hi,

I referred to the nRF7002-DK sample code peripheral_uart_nrf7002DK_DFU, but I couldn’t find CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU. Will BLE FOTA work without this configuration?

I have require to add CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU? if yes then in which file i add this?

Hello,

There might be some configuration changes needed depending on the SDK version you are using. You can add CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU in the prj.conf file, as this configuration applies to the application. For configurations related to MCUboot, place them in the mcuboot.conf file within the child_image directory.

This approach applies to NCS versions below 2.7.0. For SDK versions 2.7.0 and above, Sysbuild is used for multi-image builds.

Kind regards,
Abhijith

Hi,

I used sdk 2.6.1,

I refer  Issues with Building MCUboot for nRF7002DK Using NCS V2.5.2 and In prj.conf, I added the following:

CONFIG_BOOTLOADER_MCUBOOT=y,CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU=y

Then, in child_image/mcuboot.conf, I added:CONFIG_SPI_NOR=y,CONFIG_MULTITHREADING=y

This allowed the code to build successfully, but is this the correct approach?

Whether you are able to see your device advertising with SMP_service (the device should be visible as Nordic_UART_Service)? Try to check this with your nRF Connect mobile application. Please follow the steps mentioned in the Devacademy to verify if the BLE FOTA is working correctly.

If you check the sample provided in the post I pointed out, you could see that this configuration has already been enabled inside child_image\mcuboot\boards\nrf7002dk_nrf5340_cpuapp. And these configurations are specifically for the nRF7002DK. So the step you mentioned is not necessary.
