Hi there, I am using EC200U-CN and want to send emails via SMTP/SMTPS. But while doing so, I am getting the errors in response to SMTP AT commands. For ref
AT+QSMTPCFG=?
+CME ERROR: 58.
In Quectel SMTP Manual for EC200U, It was mentioned that SMTP is optional for EC200U-CN variant.
Is there any other way to use SMTP on EC200U-CN or need to switch to other modem ?
