Does this work on Linux? Only getting a blank on "Channel". Assume it is the wine bottle not having access to ports.

Hi, you can try connecting it to the XIAO board and using the serial port to verify the device works as expected, following the steps in this guide. If you still encounter issues, please contact our technical support team at techsupport@seeed.io for further assistance.

Re the note above about firmware 1.6.12, it says a further firmware upgrade will be released month-end (? when) to further improve breathing and respiration accuracy. Is a new update planned and if so, when will it be released? Thanks.

[nfs0619]

Thank you for your question. Firmware 1.6.12 is the latest version and can be used directly according to the documentation. The note in the documentation was not updated and may have caused some confusion. We apologize for this and will correct the note soon.

[ngaiognome-dw]

Thanks, in that case I am on Firmware 1.6.12 and as per other comments I am a little disappointed by the accuracy of the breathing and heart beat figures. It refreshes quickly and is responsive. If I stop breathing it recognises this and quickly drops to 1, but overall the reading for both are consistently higher than heartbeat as recorded on my Garmin watch, and breathing I can count breaths per minute myself. In both cases the readings seem almost double. A future update that improves accuracy would be most welcome.

Thank you for your feedback and support! We’ll keep working to make it better in future updates.

At the moment, we can receive the processed outputs (e.g., distance / breath rate / heart rate). However, for our research we would like to access the lower-level data (raw or signal-level data) if it is available, such as:

Raw ADC / I-Q samples (or any equivalent raw signal stream)

Range / Doppler FFT outputs (range profile, range–Doppler map), or intermediate frames before high-level parsing

Detailed message/protocol documentation for streaming and decoding these frames

Could you please let us know:

Whether raw/signal-level data access is supported for this sensor (MR60BHA2)?

If yes, what interface is available (UART/USB, SPI, etc.) and is there an SDK / firmware option to enable it?

If documentation is restricted, can we proceed via NDA or an official developer program?

If you need our exact model/firmware version or current data format logs, I can share them right away.

Thank you for your time and support.

The MR60BHA2 does not currently support access to any low-level data. This includes raw ADC/I-Q samples, range/Doppler FFT outputs, intermediate frames, and any other signal-level data — none of these are accessible through any interface or firmware option. The sensor only provides high-level processed outputs such as distance, breath rate, and heart rate.

Regarding customization, we currently offer tailored development services exclusively to customers with bulk purchasing requirements for specific feature needs. If your research project involves a volume procurement plan, we'd be happy to discuss your specific requirements and quantities further to evaluate the possibility of a customization partnership.

Is there anyway to set parameters used by the sensor to produce these high level values?
