Error while accessing internal temperature sensor of nrf52832

[Vimalnath]

Hi,

I using nrf52832 evk board and sdk17(S132). I want to add the internal temperature sensor reading to the ble_app_buttonless_dfu_pca100400_s132 code present in the examples folder.

I have added the "nrf_temp.h" header file and tried to call the  nrf_temp_init() function but my code is getting an error while debugging (No errors while compiling). It stops right after the init function. But the same code(with pca10040e) works with nrf52810.

When you use softdevice and when it is enabled, then TEMP peripheral is a restricted peripheral which can be accessed only through softdevice API.

sd_temp_get is the API you should use to get the internal temperature through the softdevice API.

Yes you are right. The value should be multiplied with 0.25 to get the actual temperature, right?

Hi, Sorry for late response. 

Yes, You are right, since the resolution is 0.25 degrees, each integer value represents 0.25. So if you multiply the value received with 0.25, you will get the actual temperature value.
