Very bad experience with this module. Please provide tested examples running on it.

Hi, I just purchased this days ago. There seems to be a problem with the wiring of the module (possibly something to do with the PWRKEY handling). It is unable to stream the raw NMEA message.

With the following commands, the SIM7670G modem should stream the raw NMEA message to the serial monitor.

19:14:05.501 -> AT+CGNSSPWR=1
19:14:05.501 -> OK
19:14:11.593 -> AT+CGNSSTST=1
19:14:11.593 -> OK
19:14:17.033 -> AT+CGNSSPORTSWITCH=0, 1
19:14:17.033 -> OK

However, it doesn't output anything after that.

By the way, it has enough power supply, the antenna is connected properly (tested it outdoors), serial connection is all good. Other features like the HTTP, MQTT, and Camera are working just fine.
