Bluetooth Low Energy (BLE)-Stack Software Versions

Using the internal 32 kHz RC oscillator (RCOSC_LF) as Bluetooth Low Energy sleep clock requires performing a periodic, software-based calibration of the RCOSC_LF oscillator. This functionality is included in the royalty-free TI Bluetooth Low Energy software protocal stack (Bluetooth Low Energy Stack) included in SimpleLink SDK 1.0 and onwards.
