Why CC1101::receive and CC1101::transmit both duplicate their wait timeout loops

[cqzlxl]

Details in file src/modules/CC1101/CC1101.cpp

int16_t CC1101::receive(uint8_t* data, size_t len) {
  // calculate timeout (500 ms + 400 full max-length packets at current bit rate)
  RadioLibTime_t timeout = 500 + (1.0/(this->bitRate))*(RADIOLIB_CC1101_MAX_PACKET_LENGTH*400.0);

  // start reception
  int16_t state = startReceive();
  RADIOLIB_ASSERT(state);

  // wait for packet start or timeout
  RadioLibTime_t start = this->mod->hal->millis();
  while(this->mod->hal->digitalRead(this->mod->getIrq())) {
    this->mod->hal->yield();

    if(this->mod->hal->millis() - start > timeout) {
      standby();
      SPIsendCommand(RADIOLIB_CC1101_CMD_FLUSH_RX);
      return(RADIOLIB_ERR_RX_TIMEOUT);
    }
  }

  // wait for packet end or timeout
  start = this->mod->hal->millis();
  while(!this->mod->hal->digitalRead(this->mod->getIrq())) {
    this->mod->hal->yield();

    if(this->mod->hal->millis() - start > timeout) {
      standby();
      SPIsendCommand(RADIOLIB_CC1101_CMD_FLUSH_RX);
      return(RADIOLIB_ERR_RX_TIMEOUT);
    }
  }

  // read packet data
  return(readData(data, len));
}

I don't understand what is this question about - is there some bug you'd like to report or improvement you'd like to propose?
