How much work is needed to change SDK 13 BLE 4.2 code to SDK v15 for BLE 5

[Renix]

What is the upgrade path to go from working code with SDK 13 BLE 4.2, to SDK v15 for BLE 5 for nRF52832 or nrf52840

Any help appreciated

Hi,

You should get some sense of the work required by looking at the migration guides provided with the online documentation for nRF5 SDK 14.0.0 and for nRF5 SDK 15.0.0.

Regarding SoftDevices and BLE stack usage, please note that for the nRF52840 only the S140 v6.0.0 is a Qualified Design, and we have no plans to qualify alpha versions. (Coming releases will be qualified as well, but not alphas.)

There was trouble with the old MBR on the nRF52840 which means that DFU of bootloader was not possible prior to the production release of s140 v6.0.0. If you are using a bootloader for DFU then you should keep that in mind as well.

For nRF52832 you may of course use older (production) SoftDevice versions, as they are qualified.
