ST25DV64KC Multiple Block Read/Write Error with X-Nucleo-NFC03A1: Seeking Guidance
Hello,
I want to read and write to st25dv64kc IC with X-Nucleo-NFC03A1 reader/writer. I can write up to 4 bytes with rfalNfcvPollerWriteSingleBlock() function. But when I want to write 2 blocks or more with rfalNfcvPollerWriteMultipleBlocks() function, I get an error when I want to read at the same time.
What am I doing wrong in the code I wrote, How many blocks of multiple reads and multiple writes can I do at one time?
void masterNFCV(rfalNfcvListenDevice *nfcvDev){
ReturnCode err;
uint16_t rcvLen;
uint8_t blockNum = 2;
uint8_t rxBuf[1 + 2*4 + RFAL_CRC_LEN];
uint8_t *uid;
uint8_t reqFlag;
uint8_t wrData[8] = {0x11, 0x99, 0xFF, 0x00, 0x67, 0xA5, 0xCF, 0xFF};
uid = nfcvDev->InvRes.UID;
reqFlag = RFAL_NFCV_REQ_FLAG_DEFAULT;
err = rfalNfcvPollerWriteMultipleBlocks(reqFlag, uid, 1, blockNum, rxBuf, sizeof(rxBuf), 4, wrData, sizeof(wrData) );
platformLog("Write Block %s Data %s\r\n", (err != ERR_NONE) ? "FAIL" : "OK", hex2Str(wrData, 8));
err = rfalNfcvPollerReadMultipleBlocks(reqFlag, uid, 1, blockNum, rxBuf, sizeof(rxBuf), &rcvLen);
platformLog("Read Block: %s %s\r\n", (err != ERR_NONE) ? "FAIL": "OK Data:", (err != ERR_NONE) ? "" : hex2Str( &rxBuf[1], 8));
}
Best regards
