Solution is HTTP protocol.
Use your PC as webserver. Host a page save.php or save.asp or whatever. write a code which saves data from HTTP GET method to the database.
Ex:-
save.php?lat=23.56363N&lon=45.88833E
For dynamic IP problem, use services like DynDns or NoIp. google it you will get...
Hi crackerboy,
Ok it's my bad, but still in my opinion using cheap micro is the best solution, because SIMCOM says at "least" 1s long logic low has to be applied to PWRKEY. Practically you have to make sure that it actually turned on or not, module also takes some time to boot after applying...
In fact kirtan was doing right, it only failed because of this TLS thing.
check out this thread https://www.edaboard.com/threads/196050/
Method on the above thread is absolutely correct. But if you try using gmail server, it will fail!! for the same reason.
Try using different mail server...
TLS = Transport Layer Security
TLS is a protocol for secure SMTP session. SMTP itself is very simple protocol but not secure without encryption. nowadays most of the mail server requires TLS negotiation during SMTP session, including gmail.
steps for initiating SMTP/TLS...
I think the problem is with the relay power supply. I guess filter capacitor in the relay power supply prevents relay from de-energizing quickly.
I would suggest you the following idea illustrated in the diagram below, which eliminates the need of extra power supply for just relay.
Use...
This code is written for "MikroC for PIC" compiler from Mikroelectronika
ANSELH, PORTD, TRISD are registers in PIC microcontroller
delay_ms() and delay_us() are built-in library functions of mikroC compiler.
dhruv_electro your AT command is right.
but as FvM pointed out you have to use public IP
first configure router to open incoming port (in your case port 21)forward to the local server-PC (in your case 192.168.1.9)
second- make an exception entry in your firewall, on server-PC
then find out your...
In simcom module STATUS pin is indicator of power-on state. STATUS pin is high as long the gsm module is in power-on state, never fluctuates.
In your case, it seems like power supply is not capable of delivering enough current during network activity. when you remove sim there is no RF...
Do not use MAX232.
Use MAX3232 instead. Ideally sim548c works on 2.8v TTL, compatible with 3.3v TTL.
MAX232 is R232 to 5v TTL driver, maybe that's why sim548c gets stressed out and goes into power-down automatically.
Hi mahesh.pawaskar
if you are already familiar with C and any other controller then i don't think you really need e-book for working with ATMEGA16.
just grab the datasheet, programming tool and easy compiler. I would suggest MikroC for AVR from mikroElectronica. It's easy to use, lots of...
