The problem is most likely related to the power supply of the SIM7600E module.
As it is written in the datasheet for this module, it requires 5-10V DC.
However kc868-A8S v2.0 only supplies 4V DC to pin V.
SIM7600E uses a 1084 (or analog) linear regulator in the power circuit with some voltage dropout. As a result, the SIMCOM chip does not have enough power.
This can lead to cyclic reboots and other bad things.
Colleagues from KinCony, can you explain the situation?
