This guide uses the DoorlockKeyPad built under 7.12.2 but the same basic concepts apply to any sample app and your project. A generic KBA on upgrading SDKs for Bluetooth projects provides general insights but this document is specific to this Z-Wave release.
Another minor issue with the 7.13.3 release is that it is not properly creating the .GBL files for OTA. The fix is simple:
Modify line 46 in \SimplicityStudio\v4\developer\sdks\gecko_sdk_suite\v2.7\protocol\z-wave\ZAF\ApplicationUtilities\application_properties.c
.type = 1<<6UL,
.type = 1<<7UL,
My recommendation is to click on this file in the Project Explorer->ZAF_ApplicationUtilites and make the change. When you change the code, this popup comes up:
And you should click on Make A Copy.
When the next minor release comes out this will be fixed and you will then want to delete the copy and go back to the Linked version of the file. I do NOT recommend changing the files in the SDK.
