[SOLVED] DTM_SPI software for BlueNRGM2SP chip on X-NUCLEO-BNRG2A1 is not working at all.

[clemente]

Hello to all,

I succesfully upload the DTM_SPI firmware on my X-NUCLEO-BNRG2A1 board, , using the SWD, but the BLE chip is no more responding. I'm using the X-NUCLEO-BNRG2A1 with a STM32L476RG-Nucleo, and I tried the "SampleAppThT" application to set up the BLE chip, but, as I said, I have no responce from it.

I updated the DTM_SPI Keil project with this specific define for the BlueNRGM2SP:

HS_SPEED_XTAL=HS_SPEED_XTAL_32MHZ,

LS_SOURCE=LS_SOURCE_INTERNAL_RO and

SMPS_INDUCTOR=SMPS_INDUCTOR_NONE, as indicated in DT0137 document. But without success.

The "SampleAppThT" program outpus is:

HWver 0, FWver 0
Setting BD_ADDR failed 0xff.
GATT_Init failed.
GAP_Init failed.
SERVER: BLE Stack Initialized
Error while adding Sample Service.
Error while adding service.
General Discoverable Mode 255

Could someone please tell me how to run DTM_SPI software for BlueNRGM2SP chip on X-NUCLEO-BNRG2A1?

Many many thanks.

The preprocessor settings are fine.

Can you try to test with X-CUBE-BLE2 package?

Hello Winfred, thanks for your responce.

I upload the "SimpleApp" program from "STM32CubeExpansion_BLE2_V3.1.0" to my STM32L476RG-Nucleo, but the code get in stuck here:

void MX_BlueNRG_2_Init(void)
{
  /* USER CODE BEGIN SV */
  /* USER CODE END SV */
  /* USER CODE BEGIN BlueNRG_2_Init_PreTreatment */
  /* USER CODE END BlueNRG_2_Init_PreTreatment */
  /* Initialize the peripherals and the BLE Stack */
  uint8_t ret;
 
  User_Init();
 
  hci_init(APP_UserEvtRx, NULL);
 
  PRINT_DBG("BlueNRG-2 BLE Sample Application\r\n");
 
  /* Init Sample App Device */
  ret = SampleAppInit();
  if (ret != BLE_STATUS_SUCCESS)
  {
    PRINT_DBG("SampleAppInit()--> Failed 0x%02x\r\n", ret);
    while(1);
  }

The "SampleAppInit()" function fail.

It apper that the DTM_SPI software inside the BlueNRGM2SP chip is not running at all.

Hello to all,

I resolve the problem. Now the X-NUCLEO-BNRG2A1 is working again.

I use the DTM project inside the "BlueNRG-1_2 DK 3.2.1\Project\BLE_Examples\DTM\<your_IDE>\BlueNRG-2", and modify it as follow:

• select SPI_NOUPDATER as target
• change the compiler DEFINE as follow:

SPI_INTERFACE 
BLE_STACK_CONFIGURATION=BLE_STACK_FULL_CONFIGURATION 
BLUENRG2_DEVICE HS_SPEED_XTAL=HS_SPEED_XTAL_32MHZ 
USER_BUTTON=BUTTON_1 
LS_SOURCE=LS_SOURCE_INTERNAL_RO 
SMPS_INDUCTOR=SMPS_INDUCTOR_NONE

• delete the linker define line:

--predefine=-DMEMORY_FLASH_APP_OFFSET=0x2000 

After this modification I'm be able to debug the DTM software too, and the program "SampleAppInit()" works without problem.

Thanks to all.

Just a note that

configurations SPI and SPI_NOUPDATER shall both work.
