NOTE:
The "Energy Estimate"/Evaluating connection parameters algorithms have been updated since this test, so the estimates provided by the modem should be more accurate dependent on the network environment.
We also published a whitepaper that will provide more details on how this works and how to use it properly.

Very great job!

One comment:

In my experience (Germany), the PSM parameters granted by the MNO are very different for LTE-M and NB-IoT. For LTE-M PTAU larger than 3600s are rare, while for NB-IoT it mostly works to have larger times. The consequence is, that devices which are intended to send data less frequent than an hour, are forced to wakeup anyway. My experience with the granted PSM parameters may be different in other regions or may change over the time.

But at least I would check that PSM parameter before choosing LTE-M (or NB-IoT).

Great job! This is a very helpful reference for real-world cellular IoT applications.
