ST25R3916 read blocks

[hanzigg]

Hi,

About rfalST25xVPollerFastReadMultipleBlocks and rfalNfcvPollerReadMultipleBlocks。

I use st25r3916 to read NFCV tag.The farthest reading distance of my reader can reach 70mm.When I use the command RFALNFCVPoller Read Multipleblocks, I can successfully read data between 0-70mm, but when I use RFAL ST25XVPoller FastTreadmill Blocks, when the amount is between 55 mm and 70 mm, I will fail to read, and the returned error codes are mainly 04, 09 and 21. There is no problem with tag. I can read it with other competing products in this position.

How can I determine what the problem is, the software configuration problem? Or is there not enough energy after the RF field is far away?Do you need any other configuration to use fast reading?

I hope you can help me answer it. Thank you.

Hi.

Using st25r3916' s fast read command, besides modifying cmd, what other settings are needed? Demo is set to receive baud rate of 56k. Looking through the manual of st25v02k, I didn't find any other information. Do you have any information about this?

Rgds.

Hi hanzigg,

using STEVAL-25R3916B and the corresponding PC GUI you can exercise the fast commands of ST25TV. No special config is needed for receive operation at 52kbps.
