Issue with KNTP command on HL8548

IoT Modules Legacy HL Series

Hi all,
I’m stuck since monday on a problem with NTP retrieve on my HL8548 module.
I sens to the module exactly (not?) what is described in the Datasheet, bu I get ERROR.
Does anyone can tell me what’s orng with my code?
Here are the commands that I send to the module :
AT
->OK
ATE0
->OK
AT&K0
->OK
ATZ0
->OK
AT&W0
->OK
AT+KCNXCFG=1,“GPRS”,“internet.mbqt.net”
->OK
AT+KCNXPROFILE=1
->OK
AT+CGATT=1
->OK
[GSM IO]:AT+KCNXPROFILE=1
->OK
[GSM IO]:AT+CGATT=1
->OK
AT+CSQ
->+CSQ: 13,99
->OK
AT+KBND?
->+KBND: 0100
->OK
AT+XDNS?
->+XDNS: 1, “0.0.0.0”, “0.0.0.0”
->OK

AT+KNTP=1,“145.238.203.10”,123
