Unable to access memory bank of the temperature sensor to get the temperature data.
Hi,
I am working on ST25RU3993-EVAL board for reading the temperature from RFM3200-AFR temperature sensor.
I am finding very difficult in reading the temperature code from temperature Sensor tag memory.
Can anyone help me on how can i access a particular memory location using the SDK source code provided by the ST.
Thanks in advance..

Hello Nick,
As you told, I tried to read the Tag using the C demo code in the SDK package.
I was not able to read the tag data.
It says the Tag cannot be read. I tried with 2 temperature tags RFM3200 and 2 moisture tags RFM2100.
But I couldn't read the data from any tag.
the output which i got is pasted below.

Hello,
The demo application are generated and tested with VS2017. To open the demo launch ".Applications\STUHFL_demo\STUHFL_demo.sln". This solution has 2 project. The executable demo project STUHFL_demo itself and the STUHFL DLL project. To build use in VS the menu "Build - Rebuild Solution". This first build the stuhfl.lib and dll and then the STUHFL_demo. The STUHFL_demo project reference to the stuhfl.lib file in its linker settings and build only correct when a stuhfl.lib is already generated.
Can you confirm that you are able to read USER memory from the TAGs that are part of the eval kit ?
Are you able to select one of these two TAGs from the kit and read only this, to check that Gen2_Select works for your setup ?

Hi Lakshmikanth,
Nick K. has posted below some things for you to investigate if the overall reading using selects works. I fear without trials from your side and sharing the outcome we will not be able to help you as we don't have experience with this tag.
