BLE FW OTA updates

[bjornolsen]

Hello,

I have been able to get FW OTA to work perfectly well over BLE using

CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU=y

Now I am trying to display the update progress on the peripheral (the device where I am installing the new FW).

I can imagine that it should be possible to at least show the upload progress of the image, and maybe when it reboots show that it is "installing".

I am using nrf52840 and I have a display using lvgl.

Hi, 

You can monitor the MGMT_EVT_OP_IMG_MGMT_DFU_CHUNK_WRITE_COMPLETE event to get the size and the offset. Perform division and multiply by 100.
