in IRAN the mobile operators can't support NITZ protocol. one of the ways that operator suggest to me is that I can use NTP protocol. when use AT+QNTP="example",example for any example QUECTEL M66 reply to me: ERROR.
when send this AT command: at+qntp? m66 reply to me this command: +QNTP:"210.72.145.44",123
nevertheless when I send this AT command: AT+QNTP="210.72.145.44",123 again m66 reply to me: ERROR.
how can I resolve this problem in order to set NTP and synchronization time?
