RE: is it possible to update Soft device in NRF52810 through DFU OTA

Hi,

It's not possible to do an over the air upgrade of the Softdevice because of the limited flash space on this part, unfortunately. To make a Softdevice upgrade possible you would need to be able to fit the entire Softdevicve + bootloader image into bank 0 as illustrated here: SoftDevice and bootloader

[quote user=""]what is the max size of the image that can be updated through OTA DFU ?[/quote]

This depends on the size of your bank 0 region as illustrated in the documentation I linked to above. It's usually it's around 60K.

[quote user=""]can I restrict size of the app to be uploaded?[/quote]

Only you as the owner of the private key can create an update package that will be accepted by your bootloader.

Hello Surya,
