Hello,
I faced a problem to get response when writing data to tag.
Tag communication uses ISO/IEC 15639 and CLRC663 chipset.
Tag UID and reading single block(0x20 tag command) works well. However, there is no response for writing single block (0x21 tag command).
There is no response (no Rx IRQ, no Err IRQ) when writing data to tag.
Even if the response is not received, if I read the tag, the data is written correctly.
Please let me know how can I resolve it?
- RFID Chipset: CLRC663
- Host interface : RS232
- RFID Tag Communication Protocol: ISO15693
- Steps to write data : Loading protocol already done.
: Step1 Turns on RF
: Step2. Clear IRQ0
: Step3. Save packet to FIFO - 0x42(flag), 0x21(command), 0x00(block number), 0x01, 0x02, 0x03, 0x04
: Step 4. Execute transceiver
: Step 5. Wait response (IRQ0)
