Hello everyone,
I am working with the Qorvo® QM33120WDK1 SDK. Our use case requires that, along with two-way ranging (TWR), we also exchange a small amount of application data between the initiator and responder.
I noticed that the SDK provides some FiRa APIs for data exchange (e.g., fira_helper_data_message_send), but currently they don’t seem to be working for us.
Could you please advise:
- What is the correct way to enable and use in-band data exchange together with TWR sessions?
- Are there any configuration parameters or session types we must set to allow application data to be transmitted?
- If the provided FiRa data message API is not intended for this use case, what is the recommended approach for sending small payloads during or alongside ranging exchanges?
Our goal is to reliably send/receive a few bytes of application data during TWR.
