try up to 4 times, then go to 1 hour of sleep, wake up and try 4 more, . ..
When automatically, AT JOIN reply output (same as during manual access).
The reason of ERROR returned after AT: it is already in the network state or currently
in the network.

Note: the maximum length of sending data is 64 bytes. ( ie: AT instruction length of
AT is 128+11)
Receive data without sending instruction queries to the module. If there is a downlink
data, the module emits it directly.
The reason of ERROR returned after AT: the network is not currently connected.
5.3.7 Read the time of RTC
Format Note
Instruction AT+GETRTC Get the system time
Respond
AT+GETRTC=20200325135001（year month
day hour minute second) /
AT+GETRTC=ERROR
Returning the
ERROR indicates a
failure, and the RTC
time of the Note
module has not been
successfully
calibrated through
the network.
Note：the time is automatically synchronized after the success access of the network.
So, this instruction should be done after the success access of the network.
The reason of ERROR returned after AT: the network is not currently connected.
Note2：this instruction is always effective as long as it is synchronized once and there
is no power loss(This instruction is still effective even if reset the module.)
5.3.8 Set the alarm of RTC
