Hi all i have the DWM3001CDK-DW3_QM33_SDK_CLI-FreeRTOS example open. I’m trying to find the timer/loop that changes the refresh rate of the measurement for the fira, i want to change it to around 50hz
Does anyone know where this is located or how its calculated
To change refresh rate of FiRa measurement, you need first to understand some of these FiRa parameters.
Quick explanation:
Block: Duration that conatains a complete ranging sequence.
Slot: Unit of time when one message will be send or received.
Round duration slots: number of slots in a ranging round.
Anchor/ Tag can perform only one fira ranging each block.
This means, by default here blcok duration is 200 ms, then refresh rate is 5 Hz.
If you want a refresh rate of 50 Hz, you can try as following:
Block duration = 20 ms
Slots duration = 1ms
Round duration slots = 10
