It could be, you can test by uploading a smaller image (a blinky image for example).

You can check if the size of the image would fit by checking the result of the nrf_mesh_dfu_request() function, the location where the swap bank starts is calculated at optimal_bank_address().

Which softdevice are you using ?

unmodified dfu without serial is working, application ID is 1 application version 1 and application version of zip file is 2. my code size is 132kB. with softdevice it is nearly 305kB. Is this Memory issue?

Hi Brevy,

Could you try to test again with unmodified DFU without serial, and also with some nodes with DFU with serial (not just the node connected to PC) ?

Note that, since it's background DFU, the normal application should still running when the image is being distributed.
Please make sure the application_id is matched and the application_version is increased when you update the new image.
