How to get temperature sensor value and battery level at same time?

[Big_John]

Hello

   I have a question to ask, I want to beacon the battery level and temperature. I know there is a temperature sensor inside, if I want to use saadc to get the sensor value,which channel should i use? I don't know which channel is connected to the sensor. There is a channel " SAADC_CH_PSELP_PSELP_VDD ", I think this one must be used to get the value of battery level. But how about temperature value? How should i configure SAADC? 

Please give me some information. Thank you in advance.

nRF 52840; SDK 15.2.0; s140_nrf52_6.1.0

Sorry, a bit confused here. Why do you need SAADC to read the temperature value?

Hi

I just want to read the temperature value, but i don't know how to read it. I thought i should use SAADC to do it. So if you don't use SAADC, how should i do?

you can read the chip(die) temperature using sd_temp_get() API. something like below

{
   uint32_t err_code;

   err_code = sd_temp_get(&temp);

   APP_ERROR_CHECK(err_code);

  temp = (temp * 10) / 4;

  return (uint16_t) temp;

}

Yes. It should be like this. Do we have some examples in SDK ? I found the hts example only uses simulation data.

A simple way to quickly find if any particular API is used in any of the SDK examples is to just do a text search through all the source files!
