Use temperature in Eddystone (TLM)

[Nitram]

Hello Everyone,

How could I use the temperature from nrf_temp.h in the Eddystone (TLM) example?

Eddystone (TLM) example:

<nRF5_SDK_v11_0_0 folder>\examples\ble_peripheral\experimental_ble_app_eddystone\

Thanks!

sorry forgot about that, my bad. This module is restricted so you cannot directly access it when softdevice is enabled. You have to use sd_temp_get which is a softdevice API and you can find it in nrf_soc.h.

/**@brief Get the temperature measured on the chip
 * 
 * This function will block until the temperature measurement is done.
 * It takes around 50us from call to return.
 *
 * @param[out] p_temp Result of temperature measurement. Die temperature in 0.25 degrees celsius.
 *
 * @retval ::NRF_SUCCESS A temperature measurement was done, and the temperature was written to temp
 */
SVCALL(SD_TEMP_GET, uint32_t, sd_temp_get(int32_t * p_temp));

The value returned by this function is the direct value read from the chip NRF_TEMP->TEMP register. You can use this API even when you have RC clock with calibration on triggered by temp changes.
