Hello,
It would help us understand your requirements better if you can tell us more about your workflow. Currently, the duty cycle at a mesh node is consistently maintained at 100%, as per the Bluetooth Mesh Protocol specification (Reference: Section 3.3.1).
If you want to simulate nodes with low power constraints, we do support the Low Power feature in mesh nodes, which operates with very low power. For more information about this support, please refer to Energy Profiling of Bluetooth Mesh Nodes in Wireless Sensor Networks.
Thanks,
Vamsi M
