I am using T-Mobile network in Hungary. I have used AT#REBOOT intstead of AT#SHDN.

Thanks :)

Thank you!

I spent a couple of days trying to get SNTP implemented on a UC864-G (Telit’s UMTS 3G module). If the UC864-G had a python interpreter then it would have been no problem at all. After a lot of wasted time I found your post about a handy little AT command by the name of “NITZ”. I would have discovered it eventually but you probably saved me another day or two of wasted time. Problem solved and in one line! Keep up the great work. Your notes have helped me out on many occasions.

Sorry wrong place for this comment, but I cant seem to post on another older article. I would love some help with your “Map Player”. Please email so we could corrispnd it you have time.

Thanks Jason

where did you place your super caps, im assuming right on the output of your 3.8 regulator? what about any additional circuitry that you added for these super caps? did you do anything to limit the inrush current, when the modules ?

Both work fine. Without the super-caps the Telit modem would not start or would fail to register. I’ve been able to start it with the rechargeable Lithium Ion (4.2 V) battery from sparkfun. But in our application a rechargeable battery is not going to be acceptable.

To get the Network time you must use the AT+CCLK? command. In US on AT&T Network, I have had to use AT#NITZ=7,0 before hand for the AT+CCLK? to actually return the network time. I suspect that each network could be different in this regard.

Also the time is always reset to 0 when the power is turned off and back on. So how do I read or set the network time automatically each time the modem is started up?

I used AT#NITZ=1,0, and the rest as original above commands.

Any body got a solution?
