Hello,I am trying to use the CR95HF chip in tag detect mode. I am communicating with the chip over UART and am trying to save power by putting the chip into tag detect mode so it will only wake up when a tag is detected.However, in case of a system ...
Hello! Dear ST technician! When I inventory the GB29768 tags , then read tags, In tag memory, read from area:"Could not read tag..." Warning, unable to operate, I used the chip STM32L476 +3993 provided by your company and the ori...
Hi, I bought new ST25RU3993-EVAL from Digikey. And download en.STSW-ST25RU001.zip on ST web site.ST25RU3993_Reader_Suite software Installed to windows7 PC. Also installed FTDI drivers. When i put USB cable to PC, Red LED is ON. I see new "USB Serial ...
We have a current device that utilizes the st25r3911b and the stollmann stack.Now that the Stollmann NFC protocol stack is no longer, is there a stack that can replace it in Android in the the ST world and the ST25R3916 or is NXP the only NFC soluti...
What should I take care of when using a single ended 50 Ohm antenna without AAT?What changes I need to do with the analog configures comparing to the example one given in X-CUBE-NFC6? Are there some references for this usage case?Thanks.
0x0C (Rs-B) settings in 'analogConfigTbl_NFC-6A1.c' are different with different technologies. POLL_A_106_RX: 0x51POLL_A_212_RX: 0x14POLL_A_424_RX: 0x54POLL_A_848_RX: 0x44POLL_B_106_RX: 0x1bAny principle to set them?
Hi,We bought ST25RU3993-EVAL from your company. This evaulation board worked. I installed ST25RU3993 RS. I set Reader Settings,choosed Antenna. I did everything you told in video. You mentioned in your demo video that you can read up to 11 meters.But...
Dear all ,My project is to read ST25TA64K(NFC Forum Type 4 Tag,ISO/IEC 14443 Type A) Tag with NFC03A1 Reader and hosting MCU is STM32L452.I am able to detect the Tag by Idle command.An wakeup event is getting occured after sending a Idle command.I am...
In X-CUBE-NFC6 demo, the NFCID of NFC-A CE mode is set to:static uint8_t ceNFCA_NFCID[] = {0x02, 0x11, 0x22, 0x33, 0x44, 0x55, 0x66};I wonder if this is randomly generated or there some rule to set it. For example, if I need set uid0 (first byte) to...
Hi all,I have a few questions regard the topic above.Is it an NFCA ISO standard that the PICCs will use BPSK (instead of OOK) to transmit data to the PCD for rates higher than 106? Does the ST25R3916 chipset and/or DISCO board supports speeds up to 8...
