compilation problem Segger with SDK 15.2

[Vincent]

Hello

I work for a product to produce 2 BLE products:

• several sensors with NRF52832 + LIS2DH12 (accelerometer) + HTS221 (temperature) + ICM-20689 (motion)

• a gateway with a NRF52832 + CP2102n (for USB / USB conversion)

My project is to receive the sensor information.

or this, I use 2 example with a SDK 15.2

• my gateway ble_central-> ble_app_multilink_central
• my sensor i'm using ble_peripheral-> ble_app_blinky

We made the prototype.

With your examples the sensors communicate well with the gateway in BLE.

Now I wish integrated LIS2DH12 (accelerometer) + HTS221 (temperature) + ICM-20689 (motion) functionality to my sensor

I integrated the drivers contained in the SDK 15.2

But I have a compilation problem.

"Output/ble_app_blinky_pca10040_s132 Release/Obj/nrf_twi_sensor.o: In function `nrf_twi_sensor_reg_read':"

Can you help me.

Here is my project and my bsp

Thanks,

Thanks, it compiles.

My sensor must send temperature and position (motion), and my gateway must be able to drive the LED of my sensor.

I have 3 questions :
Should I use a service? If yes which? www.bluetooth.com/.../services
Or can we modify this parameter in the program?
What is the TWI for?

Thanks,

Vincent

Should I use a service?

Yes. In the link you listed the predefined services by Bluetooth SIG are listed. You would need to create a custom service instead. In the Thingy 52 SDK, several services for some of the sensors you are using are implemented. I recommend taking a look at that. You can find the Thingy:52-SDK-zip in the list at this page.

Yes, you can.

TWI/ I2C is used to communicate with the different sensors(LIS2DH12 ,HTS221,etc).

Hi Sigurd,

how are you today?

We are making progress with the NRF.

But we have a problem with a temperature sensor (HTS221)

The fonction "hts221_who_am_i_read" => it s Ok we are a result = 0xBC

the result of temperature sensor is not correct.

This is my code

void m_temp_callback()
{
      int16_t *p_rawtemp;
      NRF_LOG_INFO("RAW TEMP : %d", p_rawtemp);
      printf("RAW TEMP : %d\n", p_rawtemp);
      temperature = hts221_temp_process(&m_hts221,  p_rawtemp)/8;  
      printf("Temperature %d C\n", temperature);   
}



void read_th()
{
      uint32_t err;
	int16_t rawhum;
	int16_t rawtemp;

      // Submit temperature read command to TWI manager
     // m_temp_callback called when data is returned
    err = hts221_temp_read(&m_hts221, &m_temp_callback , &rawtemp);
    printf("hts221_temp_read %d\n", err);
    APP_ERROR_CHECK(err);
    nrf_delay_ms(500);

}

This is a result: 

hts221_temp_read 0
Identity: 188
RAW TEMP : 0
Temperature 0 C
hts221_temp_read 0
RAW TEMP : 0
Temperature 0 C

Hi,

Did you run hts221_init() ?

What does hts221_status_read() return ?

 is  It possible to add my colegue to the discussion?
