FOTA Management for DA1469x

Hello,

I am trying to build a FOTA management architecture using the DA1469x chip. For this, I am searching for good backend management solutions like hawkBit.

As I am lacking experience in this topic, I am hoping for an experienced opinion regarding management solutions. Is there a solution which works especially well with the DA1469x chip?

My goal is to have the backend communicate with a smartphone, which then can update the chip using BLE without relying on a internet connection. Are there management solutions wich fit this use case?

Thanks in advance
