## Preflight
- Ensure vehicle is using a DSHOT ESC
- Parameter [DSHOT_BIDIR_EN](../advanced_config/parameter_reference.md#DSHOT_BIDIR_EN) is enabled
- Bidirectional DShot is configured (BDShot150/300/600 selected in [Actuator Configuration](../config/actuators.md))
- Parameter [DSHOT_TEL_CFG](../advanced_config/parameter_reference.md#DSHOT_TEL_CFG) is configured (if ESC supports telemetry)
- Parameter [SDLOG_PROFILE](../advanced_config/parameter_reference.md#SDLOG_PROFILE) has Debug (`5`) checked
