Add FOTA over BLE to nrf9151+nrf52840

[Michal]

Hi,

I have a board which is nrf9151 with nrf52840 as BLE controller connected via hci_lpuart. This works fine so far, I am able to do simple AT commands as well as doing some BLE communication. I am using TF-M for nrf9151

Now I am trying to add FOTA over BLE and I just cannot get this to work. To not complicate it even more I am trying the old way - not using sysbuild, but it doesn't help.

So what I have tried:
1. Add child_image/mcu_boot.conf
2. Add configuration to proj.conf
```

CONFIG_BOOTLOADER_MCUBOOT=y

CONFIG_SECURE_BOOT=y

CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU=y
```

I am using ncs 2.7.0

Best regards,
Michal

Hi Michal,

If you mean using BLE FOTA an nRF9151 with nRF52840, you can refer to a similar discussion here UART DFU of a nRF9160 in recovery mode via nRF5340. - Nordic Q&A - Nordic DevZone - Nordic DevZone

Best regards,

Charlie

Hi Charlie. Thank you for the reply. Please note that the mentioned case is different - there the custom UART protocol is used to communicate nrf53<->nrf91. In my case I use HCI with lp_uart variant.

Anyway I was able to get it all to compile, but I am just getting an MCU boot compilation error:

I don't think I am including cc310 and MCU boot doesn't use it as far as I read, so how do I disable this?

Best regards,
