How to enable / disable MCUboot FOTA

[jju]

Hi,

I have tested the MCUboot FOTA for my sensor with the peripheral_lbs sample project, by enabling the macros:

#Enable MCUBOOT bootloader build in the application
CONFIG_BOOTLOADER_MCUBOOT=y
#Include MCUMGR and the dependencies in the build
CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU=y

 

This works, and I can bootload the sensor via the nRF App.

On our custom board, we also use bluetooth, but when adding the MCUboot, does this add a separate BLE thread ?

And when our sensor firmware is running, we would like to do some stuff, and probably write something on our sensor display, when bootloader starts, how is this possible ?

Best regards

Thank you.
I have now read most of the information on the link, but still cannot figure out, how to make the sensor enter bootmode from my firmware ?

What do you mean by "sensor"? Do you mean the nRF microcontroller?

I ask for the clarification because sensor is often used about external hardware connected to the nRF.

Oh, sorry. Our sensor is just a custom board with the nRF52832.

For BLE, you perform DFU when the application is running.

Then you reset the device, and DFU is performed. No bootmode is needed.
