DRB Agent

DRB Agent is used to control and validate Bluetooth Low Energy (BLE) operations, including advertising, scanning, pairing, connecting to BLE devices, and exchanging data, to verify BLE-based communication and functionality.

DRB Agent Blocks

1. DRB Set Resistance

The block shall configure the DRB agent to set a fixed resistance value.

Properties

Inputs

Parameter Name	Description
Resistance Value	The resistance value to be applied by the DRB agent.

DRB Set Resistance - input parameter.

Outputs

Output Code	Description
0	Resistance set successfully.
1	Unable to set resistance.
-1	Invalid or out of range.

DRB Set Resistance - output parameter.

2. DRB Ramp

The block shall gradually change the resistance from a start resistance point to an end resistance point over a specified cycle time.

Properties

Inputs

Parameter Name	Description
Start Resistance point	Initial resistance value.
End Resistance point	Final resistance value.
Cycle Time	Total time duration to complete the ramp from start to end.

DRB Ramp - input parameter.

Outputs

Output Code	Description
0	BLE scan completed
1	BLE scan failed
-1	Invalid BLE scan request

DRB Ramp - output parameter.

Output Possibilities Configuration

3. DRB Toggle

The block shall toggle between two states based on defined start and end time points, with specified ON and OFF durations for a given total duration.

Properties

Inputs

Parameter Name	Description
Start Point Time	Time at which the toggle operation begins.
End Point Time	Time at which the toggle operation ends.
ON Duration	Duration for which the output remains in ON state.
OFF Duration	Duration for which the output remains in OFF state.
ON Duration	Total time for which the toggle operation is executed.

DRB Toggle - input parameter.

Outputs

Output Code	Description
0	Toggle operation completed successfully.
1	Toggle operation failed.
-1	Time values or durations are invalid or inconsistent.
2	Operation stopped before reaching end point time.

DRB Toggle - output parameter.
