I forgot to add the link in the previous answer (here it is).

However, in order to enable the read property for a characteristic, you have to modify the actual code. Look at step 2.F in the mentioned tutorial.

You can confirm that you have done it correctly by donwloading nRF Connect, and connecting to the Thingy. Then you should see the READ property as shown in the image below. You can read the characteristic value by pushing the arrow beside the three arrows.

Best regards,

Simon

I have enabled the read permission. The issue with this is that i had to enable notifications on my phone app to read the values. Is there a way i can read values from my phone without enabling notifications

In order to read characteristics, you will need to enable to property READ for the given characteristic. Here is a nice tutorial that explains how characteristics works, including enabling READ possibilities.

So look at what happens in the timer handler to read the temperature - and just do that ?

Yes, I have. I see that the app_timer_create() and app_timer_start() have been used to initiate and start a timer that will allow notification of the temperature values to the client continuously after a set interval. I want to change this in such a way that the only way the temperature values will be sent to the client(in this case, this is my phone), is when the client has requested for the said values. Is there a way to do this?

Have you tried looking at the source code?
