LIN bus master data send

[T-Kom]

Hi,

I am creating project in which I need to use LIN bus, I have tried to generate code from cubeMX, I have changed the BaudRate to 19200 in initialization,

see the code from Initialization :

static void MX_USART1_UART_Init(void)
{
  huart1.Instance = USART1;
  huart1.Init.BaudRate = 19200;
  huart1.Init.WordLength = UART_WORDLENGTH_8B;
  huart1.Init.StopBits = UART_STOPBITS_1;
  huart1.Init.Parity = UART_PARITY_NONE;
  huart1.Init.Mode = UART_MODE_TX_RX;
  huart1.Init.HwFlowCtl = UART_HWCONTROL_NONE;
  huart1.Init.OverSampling = UART_OVERSAMPLING_16;
  if (HAL_LIN_Init(&huart1, UART_LINBREAKDETECTLENGTH_10B) != HAL_OK)
  {
    Error_Handler();
  }
}

I have created array and tried to send it to the network

uint8_t data[] = {0x05};
 
  while (1)
  {
	  HAL_UART_Transmit(&huart1,data , sizeof(data), HAL_MAX_DELAY);
	  HAL_Delay(500);
}

I am using LIN transceiver TJA1020,

see the datasheet:

https://www.nxp.com/docs/en/data-sheet/TJA1020.pdf

I have connected NSLP pin to 5V, RX and TX to stm board, BAT pin to 12V, LIN to 12V over diode and 1kR, and when I am trying to catch the signal over oscilloscope I can see only the wakeup signal, but no data are tranfered, beyond the transceiver

Thank you very much for your time reading this, and I hope you can help me

i would really appreciate any help
