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

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,

Hi Michal,

I have not seen anyone tried this before. If nRF9160 can receiving image over BLE, there shouldn't be any issue to do update.

You may refer to the codes following exercies to implment a smp server on nRF9160 side, then test with uart to make sure there is no issue with mcuboot to do firmware udpate first.
