During initialization of CC, as I understand we should have values 0xe1,0x40,0x40,0x00But I am getting 0xe1,0x40,0x40,0x43. Im trying to manually write 0xe1,0x40,0x40,0x00 at address 0xa6, 0x00 which is failing. I ignored that and tried to write a te...
Hi,I need the suggestion such that in my PCB layout, I am trying to put all the RF chip and components will be at center of the antenna. So that I can get more space. If I seen the CR95HF Eval board the antenna part is separate and no other component...
Hi,I am getting the UUID of the device but I am unable to read or write the data. Its giving the response of 0x87 00 (No Tag). Help me to solve the problem... How to read the data from the memory...?Please check out the above commands sets...Board: X...
I am new to antenna matching so I decided to use the ST25R Antenna Matching tool V3.1. It seems simple enough, and gave me this output after adding in my antenna parameters (taken right from the datasheet): However when I simulate this circuit in Qu...
Hi.I'm graduate student, researching UHF passive RFID tag, in Dongguk university, Seoul, Korea.Thanks to offer materials like documentations, video. It was really helpful for my study. Before purchase the ST25RU3993-HPEV to measure research results, ...
Is there a way to have any MCU control the antenna function of the ST25R3916, if we use the ST25R3917, as there is a stock shortage of the 3916 ?
Hi, I am working with the ST25RU3993 HPEV board. I have configured the API with the USA frequency profile and every time I launch a new inventory it runs the pre-tuning algorithm which takes about 17 seconds. Is there any way to avoid this? I mean, s...
Hi all,On a M24SR series NFC tag, after writing a NDEF message I need to activate GPO pin to wake up the MCU. On Android with java, this method exists: activePinGPO(NFCTag tag, OnNFCListener listener);And I'm trying to find the same method for iOS. J...
Hi,After executing rfalNfcInitialize() the consumption of my ST25R3916 it's about 6mA. How could I do to power down the device to achieve 0mA? I've tried with these functions with no success:rfalSetAnalogConfig(RFAL_ANALOG_CONFIG_CHIP_DEINIT);rfalDei...
Hi Could any one please tell me the difference between ST24DV04K & ST25DV04KC chips?In datasheet for KC , it says that it is Version-C in part ordering infoBoth ICs seem to work from 1.8 V to 5.5VWhat am I missing here?Kind regards
