Arduino OTA with nRF52840

[Muqarrab]

Hi,

I am working on nRF52840 and communicating with Arduino via UART. Can I update Arduino firmware through nrf52840?

Thanks

Hi Muqarrab, 

It should be possible but we don't have any library on the nRF52840 to do programming the Arduino. 
You may need to study the UART protocol of Arduino programming to implement that on the nRF52840.

I don't see any limitation that not allow  you to program the Arduino from the nRF52.
