Firmware upgrade via BLE

[sumit-adep]

I am using nrf52810 with nrf connect 2.7.0.

Is there any provision to update firmware using BLE?
If yes is there any official document or article regarding this?

Hi,

It is not realistic to perofrm firmware update via BLE on the nRF52810 due to the limited ammount of flash. The reason is that you need to be able to fit the bootloader, as well as two application slots, and that will not fit on that device. I would recommend looking at a larger nRF52 or nRF54L series device, or consider external flash for the secondary slot.

Regardign documentation for DFU in the nRF Connect SDK, you can refe to Bootloaders and DFU.
