You can start the custom Android app from https://github.com/NordicSemiconductor/Android-nRF-Connect-Device-Manager

It needs the application with the SMP protocol on the Raspberry Pi. The protocol involves sending encoded management commands to a specific SMP characteristic on the devices. Unfortunately, we don't have such resources. You would have to implement by yourself.

Hello,

The NCS version I am using is 3.2.1
I'm using a Samsung Galaxy S23
Andriod Version 14

Currently, I test OTA with the nRF Connect App.

Yes, the custom Android application is capable of doing everything BLE related, so scanning, connecting, write/read etc, won't be a problem.

Will the link you sent me be compatible with my parameters listed above?

Also, if I wanted to do a OTA without using an application, for example with a Raspberry Pi is this possible? Is there somewhere that has the information of doing firmware updates, e.g. talking to the services/characteristics?

Hi,

What NCS version are you using? What nRF Android app are you using, nRF Connect or nRF Connect Device Manager?

Is your custom PCB capable of running the application as an nRF5340DK and working with the nRF Android app?

Is your custom Android application capable of scanning and connecting to the BLE application running on the nRF5340DK?

You can start the custom Android app from https://github.com/NordicSemiconductor/Android-nRF-Connect-Device-Manager
