HL7800 Disabling URC does not work

IoT Modules HL78
1

I’ve encountered the following bug:
When I disable the URC of UDP commands (with AT+KURCCFG=“UDP”,0,0) the URC’s still occur. It seems that the +KUDP_IND URC is suppressed, but +KUDP_RCV is not. AT+KURCCFG? reports the following:
AT+KURCCFG?
+KURCCFG: “TCPC”,1,1
+KURCCFG: “TCPS”,1,1
+KURCCFG: “UDPC”,0,0
+KURCCFG: “UDPS”,0,0
+KURCCFG: “FTP”,1,1
+KURCCFG: “HTTP”,1,1
+KURCCFG: “HTTPS”,1,1
OK
How do I disable the URC’s completely?

Edit: just tested TCP, it’s the same problem. Version : 3.4.4.3

Hi allardpotma,

Please retest with latest FW. It works fine with v3.5.1 in my side.
If still issue, please share your full AT log.

Ok, I will contact my distributor, I was not aware of a newer version than 3.4.4.3.
