Hi mt_0x,

The +KURCCFG command can only enable or disable specific protocol notifications (URCs) in RC7620-1.
(Protocol option to enable/disable URC)
• String format
• “TCPC”—TCP client session
• “TCPS”—TCP server session
• “UDPC”—UDP client session
• “UDPS”—UDP server session
• “HTTP”—HTTP client session
• “HTTPS”—HTTPS client session
• “TCP”—Both TCP client and server sessions
• “UDP”—Both UDP client and server sessions

There isn’t any AT command to disable unsolicited message +KCNX_IND in RC7620-1.
