Hello,
I’m working with a Quectel EC200U-CN module (firmware version EC200UCNAAR03A03M08) and facing an issue while sending data to the AT+QHTTPURL command.
The module connects to the network and activates PDP context successfully, but when I send the URL after the CONNECT prompt, the module either times out or throws +CME ERROR: 726. It seems that the module is not accepting the input text or file contents after showing CONNECT.
I have tested this behaviour with both QCOM utility and Tera Term, and in both cases, the issue persists — neither manual typing nor sending a .txt file works after the CONNECT prompt.
[2025-10-30_12:45:25:719] AT+QHTTPURL=19,30
[2025-10-30_12:45:25:719] CONNECT
