BLE mesh, central mode and DFU over BLE, which NCS v2.1.2 example is better to as code base?

[Felix Shih]

Hi Nordic,

I need BLE mesh, central mode for TAG to pair and DFU over BLE functions, can you guide me which example in NCS v2.1.2 is better to as code base?

Hi dejans 

nRF5340 is our customer's decision, we can not change it.

Now I want to try DFU over UART first, then DFU over BLE.

Does the following URL steps also apply to nRF5340? I try it but seems not work.

 Add DFU support to your application

Hi,

You can follow this guide, but only if you update one core at the time. For updating nRF5340 over BLE, you would probably want to update both cores simultaneously as shown in the example here. Additionally, you can have a look at simultaneous multi-image DFU, FOTA updates, and MCUboot serial recovery in working with nRF5340.

Best regards,
Dejan
