Hello, I using SIM7600E and try set to transparent mode.
I have problem with command AT+NETOPEN after i called this command
I get response AT+NETOPEN\r\r\nOK\r\n\r\n+NETOPEN: 2\r\n
Ok, I read it’s a port overflow error code
I tried called AT+NETCLOSE, AT+CIPCLOSE=0, try wait for few seconds and try send AT+NETOPEN again, but doesnt work
