Does this result mean that it can handle 3 months data transmission with the current setting. Thanks for your help. I have also attached the screenshots on a new device that I have bought but the application wont detect it. I have installed everything including trying to update the firmware but the device wont be found. Is there anything am not doing right?

Hello, 

I can see that you have a nRF9160 rev 2 device, but are you using the nRF9160DK or the Thingy:91?

After using the power profiler link you sent to me, I had this result from the calculations. Does this result mean that it can handle 3 months data transmission with the current setting.

Please note that the power profiler is meant for evaluation purposes only and will not give the exact numbers in every use case. This is due to several parameters you are not able to control. Some parameters can be requested by the UE, but in the end it's the network that decides most of them. These parameters can have a significant impact on current consumption, and in order to get an idea of what to expect when you connect to the network in your area.

Depending on the end product you design and amount of components, i.e. sensors, etc. this will impact the current consumption of the whole system. 

I have installed everything including trying to update the firmware but the device wont be found. Is there anything am not doing right?

 Is the device showing in the device manager on your computer? Please verify that the USB cable that you are using supports data transmission. 

Have you gone through the nRF9160DK Getting started or the Thingy:91 Getting started?

Kind regards,
Øyvind
