Sending RFID commands - issueISO15693Command is private

[yaneevH]

Hello,

I am trying to use this code and the PN5180 to configure and then read commands from the MLX90129 Sensor Tag.

As per page 14 of this pdf I need to send specific commands to configure the sensors before reading first. Below is a screenshot of the first couple commands:

I am attempting at issuing just the first line right now as follows:

void mlxConfig(){
  uint8_t cmd[] = {0x43, 0x21, 0x09, 0x71, 0x70};
  uint8_t *readBuffer_0;
  nfc.issueISO15693Command(cmd,  sizeof(cmd), &readBuffer_0);
}

But am getting the following errors:

error: 'ISO15693ErrorCode PN5180ISO15693::issueISO15693Command(uint8_t*, uint8_t, uint8_t**)' is private
   ISO15693ErrorCode issueISO15693Command(uint8_t *cmd, uint8_t cmdLen, uint8_t **resultPtr);
                     ^
MLX_Comm:326: error: within this context
   nfc.issueISO15693Command(cmd,  sizeof(cmd), &readBuffer_0);

Is this not the way that that commands should be sent? If I put the data into the sendData function it compiles fine.
How would I go up about issuing the necessary commands for configuration and then reading from it as the pdf instructs using this code?

Hello Yaneev, I think both ways - as you tried - are wrong. The configuration you have to do upfront is not part of the ISO15693 standard. Therefor the command issueISO15693Command does not work. Using sendData instead was a good guess, but as shown in the screenshot, I think you have to write to the EEPROM at certain addresses instead of sending data. Personaly I have never had any use case to do so. That is why the class PN5180 is missing the method writeEEprom and only has an implementation to read from the EEPROM. If you want to configure your tags, I think you have to implemented this missing function. From the PN5180 datasheet the command must be: The call has to be implemented as follows: Feel free to add such a function to the library and let me know, so I can integrated it into the code. Best Regards, --Andreas.

I think maybe an image you meant to post didn't upload? There is no content after the two lines with colons you have,

From the PN5180 datasheet the command must be:

The call has to be implemented as follows:

I can for sure try writing the writeEEprom method. But since I am still not completely understanding the code (and my C++ abilities are limited), would you be able to give a quick outline of how this method might look like and what aspects would go into creating it?

Thank you!

Hallo Yaneev, sendingData is a different command and does not write to the EEPROM! Try something like this: #define PN5180_WRITE_EEPROM 0x06 bool writeEEPROM(uint8_t addr, uint8_t *buffer, int len) { uint8_t cmd[2] = { PN5180_WRITE_EEPROM, addr }; SPI.beginTransaction(PN5180_SPI_SETTINGS); bool rc = transceiveCommand(cmd, 2, buffer, len); SPI.endTransaction(); return rc; } Regards, --Andreas.
