Measure signal strength

xxx_88 · January 2, 2019, 7:25pm

Hello,
Are there any-way to measure strength of received signal while calculating TWR ?
I’m using original API (not latest version, but that can be replaced easily).
Thanks !

Hi,

Please refer the section 4.7(Assessing the quality of reception and the RX timestamp) in DW1000 User Manual.This section clearly explain how to measure received signal strength.

dwt_readdiagnostics() API function reads the RX signal quality diagnostic data which can be used to measure received signal strength.

Thanks & Regards,
Deepa

Can you give any detail on how to convert the values in the diag struct to something like decibels of signal strength? Thanks.

The formula is in section 4.7.1 of the DW1000 user manual.
