FOTA over Thread using cloud

Adolfo

Hi, 

I am considering to build a line of products using the nRF 5340 product and I am considering the options to perform FOTA.

So far the option I learned from the Intermediate training for customers is primarily FOTA over BLE only.

I have seen a previous post but it is 2 years old about this topic so I will ask again because perhaps the conditions have changed and maybe there is additional support now.

Is there support from the nRF libraries to perform FOTA over Thread using a cloud API?

Going one step lower, if a Thread border router that my device is connected to has permanent internet access, is it possible for the nRF 5340 to connect to the internet over Thread?

Can I use the FOTA download library (i.e. Download client FOTA download — nRF Connect SDK 2.6.99 documentation (nordicsemi.com)) to download the update over the internet using the Thread protocol?

Thank you,

Adolfo

    Hi Adolfo,

    Thread does not offer a proprietary FOTA (Firmware Over The Air) method. However, since Thread does not define its own application layer, you can implement your DFU in your application layer. You can use libraries such as DFU Target or FOTA Download.

    For a deeper understanding of DFU in the nRF Connect SDK, you can look at Lesson 8 – Bootloaders and DFU/FOTA in the nRF Connect SDK intermediate course on DevAcademy.

    Going one step lower, if a Thread border router that my device is connected to has permanent internet access, is it possible for the nRF 5340 to connect to the internet over Thread?

    Yes, the border router connects the Thread network to other IP-based networks, such as Wi-Fi, which means that devices on the Thread network can connect to the Internet.

    Best regards,
    Marte
