Hi,

Did you run hts221_init() ?

What does hts221_status_read() return ?

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

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.

[quote userid="75021" url="~/f/nordic-q-a/44083/compilation-problem-segger-with-sdk-15-2/174384"]What is the TWI for?[/quote]

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

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

You did not set TWI_ENABLED to 1.

Thanks, for you answer, but I made the changes but I still have the same error

I updated the program here

https://www.dropbox.com/s/ipqh8rnod2xr5md/nRF5_SDK_15.2.0_9412b96.7z?dl=0

I do not understand with 
#ifndef NRFX_TWIM_ENABLED
#define NRFX_TWIM_ENABLED 1
#endif
the file "nfrx_twil.c" is disabled


Thanks for your help 

Vincent

I was looking at the project in ble_app_blinky\pca10040\s132\ses, but I see the capteur project now.

Please add the following files to the project:

1) nrfx_twim.c , found in sdk_folder\ modules\nrfx\drivers\src
2) nrf_drv_twi.c, found in sdk_folder\ \integration\nrfx\legacy
3) nrf_queue.c , found in sdk_folder \components\libraries\queue

In sdk_config.h, set the following defines to 1:

NRF_QUEUE_ENABLED (line 7083)
NRF_TWI_MNGR_ENABLED (line 7126)
TWI_ENABLED (line 5557)
TWI0_ENABLED (line 5603)
TWI0_USE_EASY_DMA (line 5609)

And if you are also using TWI 1 instance, set these to 1 also:
TWI1_ENABLED (line 5617)
TWI1_USE_EASY_DMA (line 5623)

Hi Sigurd,

thanks for you answer, I don't anderstand "he screenshot you uploaded does not match the project uploaded on the dropbox.", you use this " nRF5_SDK_15.2.0_9412b96\examples\ble_peripheral\ble_app_blinky\capteur\s132\ses"?

I have enabled #define NRFX_TWIM1_ENABLED 1

but i have a new error :

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

Thanks for you answer.

Vincent

Hi,

The screenshot you uploaded does not match the project uploaded on the dropbox.

If you are using the nrf_twi_mngr, please make sure that you have NRF_TWI_MNGR_ENABLED set to 1 in sdk_config.h

Best regards,

Sigurd
