B4R Question Read cell tower date & time

[Shay]

Hi
Using the GSM/GPRS module (I have D6 module)
How can I read the date and time from the cell tower?

 

[Erel]

Have you started with this example: https://www.b4x.com/android/forum/t...-the-arduino-with-sms-messages.66770/#content ?
Does it work for you?


You can try to run AT+CCLK?

 

[Shay]

Yes and it is working
I will try it (how do I run manual commands - is it described in the above example?)
b.t.w where do you get the commands, since I need also to get the module IMEI number (or some other unique number for licensing)

 

[Erel]

b.t.w where do you get the commands,

Search Google for GSM AT commands.

 

[Shay]

I tried the following, and I am getting "false"

Public Sub CheckTime As String
    Return SendCommand("AT+CCLK?",False)
End Sub

 

[Shay]

I added it into timer after 5 sec, and I am getting this: (I removed the log and enabled SMSevents)
(current time and date is 22/11/2017 23:16)

see also the gibrish I am getting sometimes, why?

Not all networks and sim chips support this command.

 

[Shay]

Is there other command?
Do you know which network in Israel support it?
What about the ��� I see?

 

[Erel]

I never worked with the module you are using. I don't know whether there is any other command to check the time.

Do you know which network in Israel support it?

No.

What about the ��� I see?

Hard to say but I don't think that it is relevant.

 

[Shay]

After lot's of digging
the "�" is baudrate issue - reduced to 9600 and now it is ok

Regarding the clock - the CCLK command is not supported yet (or ever I guess) in this module
there is other command but it can work only 1 time (why??)
I am opening ticket with the vendor
