Is there going to be any ongoing support for S130?

[Roger Clark]

I just downloaded SDK 13 and noticed that S130 (nRF51x) is no longer supported.

Does this mean that there won't be any bug fixes for the SDK / API for anyone using the nRF51x ?

Or will Nordic be releasing new versions of SDK 12 if bugs come to light ?

Also. From what I remember the bootloader system was changed in SDK 13 to go back to being similar to SDK 11, in that it no longer uses flash storage for storing flags . Which I presume is an improvement, now not available on the nRF51 - unless you use SDK11 which I don't think has the secure bootloader

SDK 13 also seems to have some additional examples, which I don't think are necessarily hardware related.

e.g. there is the experimental_ble_app_lns but LNS seems to have been introduced in SDK 10

infocenter.nordicsemi.com/index.jsp

e.g. components\ble\ble_services\experimental_ble_lns

So I presume nRF51 users would need to try to modify those SDK13 examples to work with S130

Hi Roger,

You are right. Development and support for the nRF51 is stopped from SDK v13.

We will have bug fix release if it's needed. But there is no schedule for that just yet.

If you want something implemented from sdk v13 (the latest SDK now is v14) you would need to port it to work with nRF51.

Thanks.

I will continue using SDK 12 for nRF51.

Is there any reason to migrate existing nRF52 code running ok using SDK 12, to SDK 14 ? I didn't think it would build without being modified ( ported ) to SDK 13 or SDK 14?

Ps. Actually I have a SDK11 nRF52 application as well, but I think the same thing applies.

here are some reasons to migrate with the nRF52832: SDK13(support for 20 concurrent links), migrating further to SDK 14 gives you also support for BLE5 2Mbps mode(S132 v.5).

Thanks Daniel

I'm sure for people who need those features, it may be worth the effort to port their code to SDK 13 or 14.

I don't use or need either of those features, so I don't see a pressing need to spend time porting code.
