rfalST25xVPollerGenericWriteMessage() fails writing to mailbox Hi,I have some code for reading/writing to a mailbox from the ST25R3916B transceiver to a ST25DV04KC-I tag. The read passes but the write fails every time.My reading function looks like this ... bool nfc_read_mailbox(void)
{
uint8_t pointer;
uint8_t reg;
uint8_t pwd[8] = {0, 0, 0, 0, 0, 0, 0, 0};
uint8_t pwdLen = 8;
uint8_t pwdNum = 0;
uint8_t msgLen;
ReturnCode err;
uint16_t rcvLen;
uint8_t rxBuf[256];
bool result = false;
memset(&rxBuf[0], 0x00, sizeof(rxBuf));
/* Open RF configuration security session */
err = rfalST25xVPollerPresentPassword(RFAL_NFCV_REQ_FLAG_DEFAULT, NULL, pwdNum, pwd, pwdLen);
if (err == RFAL_ERR_NONE)
{
/* set MB_MODE to 1: Enabling fast transfer mode is authorized.*/
pointer = ST25DV04K_SYSTEM_CONFIG_MB_MODE;
reg = ST25DV04K_REG_MB_MODE_FTM_AUTHORIZED;
err = rfalST25xVPollerWriteConfiguration(RFAL_NFCV_REQ_FLAG_DEFAULT, NULL, pointer, reg);
if (err == RFAL_ERR_NONE)
{
/* set MB_EN to 1: Enable FTM. Read, update and write */
