Hello all i am using nRF52 DK And wish to send the temperature sensor values to the users smart phone. I have checked with the tutorial and used the sd_temp_get() function to get the temperature. But now i wish to use another temperature sensor

 The temperature sensor that i am using is analog. As mentioned above I have already gotten the temperature value using sd_temp_get().I also wish to send the values of voltage connected to another analog input to the user smartphone. I am stuck at the stage to notify/read the temperature and voltage values to the respective characteristics. Could someone guide me in this case. Any inputs would be  helpful.

Hi awneil Thanks for reply as mentioned in the question i have already used the tutorial and gotten the temperature using sd_temp_get(). I need help with the external temperature sesnor and battery voltage updating (values).

So not sure where your problem lies?

As far as updating the characteristics is concerned, it makes no difference how the data was obtained - so the tutorials should be applicable.

Are you just asking how to read the external sensor?

I am using lmt85 at P0.31 and battery voltage at P0.29. I have recieved the values for battery voltage using SAADC. so how do i pass these values to the characteristic.

Yes may be i misquoted the question. I apologise. For getting SAADC values i have used nrfx timer and its really confusing as to how to update this in respective characteristic. As the tutorial uses app timer i am unable to corelate.I wish to implement similar functionality as to how sd_temp_get() returns temperature every 50us from call .thanks a lot for replying.
