Hi Tom,

You can get some callbacks by registering them using img_mgmt_register_callbacks(). See this thread.

Hi Einar,

Is there a way for our application to be notified if there is a write to the FOTA service? After looking at "smp_bt.c" it seems as the code is self-contained.

We would like to control when an OTA process can occur within our application code and terminate the active connection if certain states haven't been met.

I see that there is a define "CONFIG_MCUMGR_SMP_BT_AUTHEN" to restrict when the FOTA service is written to but we are not authenticating the connection.

We would also like to avoid modifying any zephyr code.

Thank you,

Tom

Hi Tom,

There is no Bluetooth transport in the MCUboot bootloader, so with the nRF Connect SDK the application is responsible for transport. Therefor, it must implement the FOTA service as demonstrated by the SMP Server Sample. With the nRF5 SDK this was different, as the whole DFU process, including transport, was handled by the bootloader. This is not supported with the nRF Connect SDK.
