Question:
I have a problem with the GSM modem USR-GPRS232-730.
Purchased through Alibaba, the first time it is used.
Through the application to use the modem, the message is sent successfully, but whenever a URL is routed, the CME ERROR error is returned: 58.
Can you tell me what this fault is and how to correct it?
Answer:
Error 58
Invalid command or command format error.
