For modem FOTA via LTE? Then no, not that I can think of.

This is good news, on the modem FOTA update without having to use the debugger.

Are there any hardware requirements to make this possible?

We are implementing a similar design, and would like to be able to support this feature so if there are any hardware requirements we need to know what they are to be able to get them into the circuit design.

Thanks

Hi,

[quote userid="16133" url="~/f/nordic-q-a/48879/nrf9160-modem-firmware-update-without-swd"]Is it possible to update the modem firmware once the product is on the field? [/quote]

Yes, that will be possible. The modem FOTA solution is however not ready for release yet. If you implement application FOTA now, it should be possible in the future to update the application to a version that support modem FOTA, and then do the modem FOTA after doing the application FOTA update first.

[quote userid="16133" url="~/f/nordic-q-a/48879/nrf9160-modem-firmware-update-without-swd"]In our architecture, the nrf9160 is connected by UART to a nrf52840. Can I flash the new firmware using the nrf52?[/quote]

I believe it will be possible in the future, but modem FOTA over LTE will likely come first.
