## Bidirectional DShot (Telemetry)
## Bidirectional DShot
<Badge type="tip" text="PX4 v1.16" />
Bidirectional DShot enables ESC RPM (eRPM) data collection from each ESC at high frequencies. This enhanced telemetry significantly improves the performance of [Dynamic Notch Filters](../config_mc/filter_tuning.md#dynamic-notch-filters) and enables more precise vehicle tuning.

### Configuration
### Configuration {#bidirectional-dshot-configuration}
To enable bidirectional DShot, set the [DSHOT_BIDIR_EN](../advanced_config/parameter_reference.md#DSHOT_BIDIR_EN) parameter.
:::info
The system calculates actual motor RPM from the received eRPM data using the [MOT_POLE_COUNT](../advanced_config/parameter_reference.md#MOT_POLE_COUNT) parameter. This parameter must be set correctly for accurate RPM reporting.
