i used to STRU3993 Eval
I got the result based on the following code.
I wonder what that result means.
It seems to be the result of the antenna performance here.
If it is the output of the result for the antenna performance,
I wonder what function should be used to get the result of the power obtained through the tag, that is, the dbm/rssi value.
Hello esoft.1,
could you let me know which version of the ST25RU3993 SDK you are using ? Have you modified the demo sources for your screenshot and if so could you share your modified source ?
Your screenshots are showing tuning values from the tuning tables of the FW.
To get RSSI values for transponders that are in the field the easiest way is to run a inventory scan. For each inventoried transponder the ST25RU3993 evaluation board send back all information collected when a transponder was found. This data is replied in the inventoryCycle callback with the STUHFL_T_InventoryTag and STUHFL_T_InventoryStatistics data field.
The STUHFL_T_InventoryTag has field for the measured RSSI log and lin values of I and Q during the transponder reception.
For more details of the RSSI measurement please have a look the ST Application Note AN4971 "Received signal strength indicator (RSSI) for ST25RU3993"
