I would like to write my own program which can send messages and read from the mailbox on an st25dv-i2c. On one end I have a st32-L0 nucleo board which can access a x-nucleo-nfc04A1 mailbox via i2c. On the other end I have a st32-L433 connected to a x-nucleo-nfc06A1 (SPI). I have been unable to read or write to the mailbox via RF.
My current progress on writing to the mailbox is:
1) I have configured registers A and B using the iso15693 register map provided by the disco GUI
2) I have encoded my message, which is a single byte with a value of 1, added CRC and SOF/EOF.
SOF, 0x02, 0xAA, 0x02, 0x00, 0x01, 0x5D, 0x03, EOF ->
21 20 02 02 02 20 20 20 20 20 02 02 02 02 02 02 02 08 02 02 02 08 80 08 08 80 02 02 02 04
3) I have done the following commands: Stop, Reset RX Gain, Clear FIFO
4) I have updated the num tx bytes register 2 with: tx_len << 3 where tx_len = 30 for this case
5) I have written the encoded message to the FIFO, read FIFO to check, and sent without CRC
I have no response from my st25dv. However, sending the non-encoded message above via the GUI and a discovery board (w/out SOF and EOF) does work.
Am I missing something? Any help is appreciated.
