OTA DFU nRF52 master to slave

[PeteKcSum]

Hi Nordics,

I know it has been asked over and over again about doing DFU of slave nrf52 using a central nrf52.

devzone.nordicsemi.com/.../ota-dfu-application-firmware-by-ble-central-device
devzone.nordicsemi.com/.../ota-dfu-from-nrf52-to-nrf52
devzone.nordicsemi.com/.../84931

There is no example, but i stumbled upon the following
infocenter.nordicsemi.com/index.jsp

which seems to be  using a BLE to update a nrf52 via PC . If it is , would it be possible to port this code over to an external MCU which controls the nrf master to perform a similar update ? thx.

This uses SoftDevice serialization via pc-ble-driver to do the DFU, so it is not so relevant if you are using a non-Nordic MCU as DFU master. The closes would perhaps be this unofficial implementation: Serial DFU Host Application (By using C programming language).

ok, thx. will follow and see if it works.
