we want to support the serial bootloader with SDK13, but find that the example is Experimental: Serial Secure DFU Bootloader, can we use it stably? the SDK14/15 don't Experimental, or how to migrate rapidly from SDK13 to SDK14/15?

Hi,

Examples marked as experimental does not have a full testing procedure designed to uncover all flaws we can imagine, so there may be unknown bugs. We generally do not recommend using experimental examples as stable code in end-user products without testing the implementation very well yourself. For a proof of concept or for use in early development experimental examples are well suited.

In the end it's your choice if you want to use the experimental version in SDK 13 or migrate to SDK 14. I recommend migrating to SDK14, and this is not too hard to do if you follow the migration guide here. You may want to consider moving directly to SDK14.2.0 since it's API compatible, but has some minor bugfixes which may be nice to have.

Best regards,
Rune Holmgren
