Heart rate demo using QFAAC0, SDK v4.4.0 and SD v6.0.0

[Robert Taylor]

Hi,

Does the heart rate demo in SDK v4.4.0 work with SD v6.0.0? I'm using the QFAAC0 revision of the NRF51822. The demo works fine with SD v5.2.0. Is there anything special I need to do? Or does it not work at all?

Thanks, Robert

Follow up. If I order a new nRF51822-DK from Mouser will I get the latest chip rev?

An SDK version can only be used with the softdevice it was made for. This is always stated in the SDK's release notes. SDK 4.4.0 will not work with S110 version 6.0.0, for that you'll have to use SDK 5.1.0.

The official recommendation is to not go to production with S110 version 6.0.0 on a first revision chip, but it should work for development if you want to. Be aware of this problem however.

The best option for moving forward is to get hold of a new kit. I believe that a new kit from Mouser should be a second revision chip now, but you can check this by verifying that you get hardware version 2.1.0 or later.

Thanks!

I am in search of this answer as well! I will need the latest version very soon. How can we be sure what we are going to buy will be the latest?

The distributor should know which version they have in stock. Version 2.1.0 and later has second revision chip.

You can also contact your regional sales manager, which should be able to help you. PM me your location if you don't have his contact information.
