Hi! I was wondering if there is an application to test the signal strength between ST25R3911B Disco and STEVAL-Smarttag1. Many thanks.

Hi again,

Is your R6 resistor value different than 0 ohm ?

If this is the case, then you should probe the side which is connect to C13A. According to the schematics, this is where VEH is directly connected.

Best regards.

Dear JL. Lebon and Ulysses Herniosus,

Thanks for the advice, I was able to measure the voltages. However, I was wondering if it is possible to measure the current obtain by the RFID antenna on the STEVAL-SMARTTAG.

Thanks for your help and have a great day,
