7600X connect Arduino

Arduino Demo

1 Mainly make the following adjustments, change the program baud rate to 115200, the original program baud rate is 9600, the default baud rate of SIM7600 is 9600, which does not match.

2 Change the wiring, remove the PWR switch control line, the new version of SIM7600 is powered on by default, this function is not used.
3 Please confirm that the TTL level of Arduino is 3.3V, and the default level of SIM7600 is 3.3V
