nrf_temp_read() or sd_temp_get(&t) fault with S132

[manymany]

Hello,

I try to read temperature with embedded sensor. Works well with example but crash when using SoftDevice 3.0.0 on nRF52328. Was working with SoftDevice 2.0.0.7.alpha.

Difficult do find information about this functions in the online documentation.

Thanks.

Hi,

The softdevice function sd_temp_get() is documented in the infocenter.

I tested it using the ble_app_uart example in SDK 12.2 with S132 v3.0.0 softdevice, and it works fine. How do you use it in your application? Did you get any error codes in return when calling the function?

Best regards,

Jørgen

No just replace nrf_temp_read() by sd_temp_get().

Remove also other stuff NRF_TEMP-> ...

//Without S132
float temp;

//   NRF_TEMP->TASKS_START = 1; /** Start the temperature measurement. */
//  NRF_TEMP->EVENTS_DATARDY = 0;
//  temp = nrf_temp_read()/4.0;
//  NRF_TEMP->TASKS_STOP = 1; /** Stop the temperature measurement. */
  
//With S132
 
int32_t  t;
sd_temp_get(&t);
temp = t/4.0;

And this is not working? Did you initialize the softdevice before calling sd_get_temp()?

Thank you very much Jorgen, I've just managed to get it working. I had not removed NRF_TEMP-> ... things. Now works fine. I spent a lot of time moving from S132-2.0.0-7_alpha to S132-3.0.0 mainly because of that. Some comments on that could appear in the temperature example.

Great that you got it working! Access to the TEMP peripheral is Restricted when running the softdevice and you should only access it through calls to softdevice functions.

Yes. Sorry if I insist but I think temperature is a good basic example to understand the concept of Sofdevice and this should appear in SDK example/temperature.
