Hi,

I have the SIM7600E-H 4G DTU modem which is plugged into my CR350 data logger with a null modem cable on the DB9 RS232.

When I monitor the serial communication of my data logger on the serial port, I can see the RDY message from the modem when it is online.

I also see it in Jasper (cellular network manager) and I can PING the modem from my server but I can’t find the AT+ command to put in the modem so that I can access my data logger on port 6090.

Thanks in advance.
