I’m facing QNTP error when trying to sync the internal RTC. On the same module I’ve used a different SIM Card and the command works just fine.
How can I debug it to know what is happening?
AT+QNTP=1,"0.br.pool.ntp.org",123,1
ERROR
I still can make MQTT and HTTP(S) requests, but AT+QNTP returns the above message.
