Undesired prints (ServerDrv::availData: SpiDrv not available) appear in console when using the library

[grisharav]

Describe the bug

server_drv.cpp contains debug macros which cause undesired serial prints

#define _DEBUG_

#define KH_WIFININA_SERVER_DRV_DEBUG   1

And usage:

uint16_t ServerDrv::availData(uint8_t sock)
{
  if  (!SpiDrv::available()) 
  {
    // KH
#if (KH_WIFININA_SERVER_DRV_DEBUG > 0)
    Serial.println("ServerDrv::availData: SpiDrv not available");
#endif    
    return 0;
  }
 
  // KH
#if (KH_WIFININA_SERVER_DRV_DEBUG > 2)    
  Serial.println("ServerDrv::availData: SpiDrv OK");
#endif  

  WAIT_FOR_SLAVE_SELECT();
  // Send Command
  SpiDrv::sendCmd(AVAIL_DATA_TCP_CMD, PARAM_NUMS_1);
  SpiDrv::sendParam(&sock, sizeof(sock), LAST_PARAM);

  // pad to multiple of 4
  SpiDrv::readChar();
  SpiDrv::readChar();

  SpiDrv::spiSlaveDeselect();
  //Wait the reply elaboration
  SpiDrv::waitForSlaveReady();
  SpiDrv::spiSlaveSelect();

  // Wait for reply
  uint8_t _dataLen = 0;
  uint16_t len = 0;

  SpiDrv::waitResponseCmd(AVAIL_DATA_TCP_CMD, PARAM_NUMS_1, (uint8_t*)&len,  &_dataLen);

  SpiDrv::spiSlaveDeselect();
  
  // KH
#if (KH_WIFININA_SERVER_DRV_DEBUG > 2)
  Serial.print("ServerDrv::availData: len =");
  Serial.println(len);
#endif

  return len;
}

Thanks for your interest in the library.

That's for the debugging purpose when there is some kind of error. It's so simple to remove, if you don't want, by

#define KH_WIFININA_SERVER_DRV_DEBUG   0
