PlatformIO doesn’t have first-class support for the Gecko SDK (which includes BLE support).
SiLabs BLE stack is tightly integrated with Simplicity Studio, and its BLE APIs rely on a lot of autogenerated code and project configuration files (.slcp, .hwconf, etc.).
The Arduino core for XIAO MG24 available in PlatformIO is limited and doesn’t include BLE functionality like in Simplicity Studio. If your main goal is BLE, Simplicity Studio is currently the best-supported environment.
