Hello, I am creating a Bluetooth application on a custom board. I used the STM32WLSS board and the BLU-NRG-232N. I used the SensorBLEDemo project as a base for my code, then integrated it into a separate project to make sure it worked as expected.

[AMACH.1]

However, when I ran the code on my custom board, I am not getting any data from the BLE. I am stuck at line hci_reset().

I initialized the SPI and BLE but when I ran the debegger, I did not reach the line before hci_reset(); when I set the interrupt to PULL UP the CS pin always remains in the LOW state and when I set it to NO PULL the CS pin always remains in the HGHT state.

 I have attached my code below. Can anyone help me diagnose this problem?

static uint8_t Sensor_DeviceInit(void)

{

 uint8_t ret;

 //uint16_t service_handle, dev_name_char_handle, appearance_char_handle;

 //uint8_t device_name[] = {SENSOR_DEMO_NAME};

 uint8_t hwVersion;

 uint16_t fwVersion;

 uint8_t bdaddr_len_out;

 uint8_t config_data_stored_static_random_address = 0x80;

 //Sw reset of the device

 static uint8_t Sensor_DeviceInit(void)

{

 uint8_t ret;

 //uint16_t service_handle, dev_name_char_handle, appearance_char_handle;

 //uint8_t device_name[] = {SENSOR_DEMO_NAME};

 uint8_t hwVersion;

 uint16_t fwVersion;

 uint8_t bdaddr_len_out;

 uint8_t config_data_stored_static_random_address = 0x80;

 //Sw reset of the device

 hci_reset();

 TIMER_IF_DelayMs(2000);

 getBlueNRGVersion(&hwVersion, &fwVersion);

 ret = aci_hal_read_config_data(config_data_stored_static_random_address,

                 &bdaddr_len_out, bdaddr);

return ret;

}();

 TIMER_IF_DelayMs(2000);

 getBlueNRGVersion(&hwVersion, &fwVersion);

 ret = aci_hal_read_config_data(config_data_stored_static_random_address,

                 &bdaddr_len_out, bdaddr);

return ret;

}
