My original thread was locked, so I'm reposting here.
I'm now using CCS 9.0.1.00004 and updated our project to use the latest simplelink_cc13x2_26x2_sdk_3_10_00_53 SDK. Unfortunately, the issue still persists. Limited discoverable mode (GAP_ADV_ENABLE_OPTIONS_USE_DURATION) still crashes the radio if you're connected when the advertising duration timer would end.
See the "Original question" link above for the original details.
