Its my first post here ...
Finally I'm able to run arduino mega and gsm 800L...On 115200 serial , 9600 gsm bauds..
Now few problems..
Im able to
-Send SMS
-retrieve received SMS to serial window by from one index location at a time
-Only some AT commands responds on serial
Like AT ,ATE ,ATA,ATH,ATE.. While if a call is incoming , serial window Shows "RING"
ANY other commands like AT+xxxx or ATDxxxxx don't work and give me error
For e.g :
ATD12345678; i press enter and get the following reply
"AT+
ERROR"
All i wanna to do is few simple tasks using Arduino mega+sim800L :
1-Received command("ON/OFF") through SMS and Reply confirmation SMS
OR
2-Make a call when some pin goes high or low
Also how to extract info/command from sms , because ON SERIAL MONITOR it show sender number , at command and time then it shows actual SMS..
Ive used most of the libraries available on internet but none works , and the only working one is cristianteib(serial,readsms,sendsms) ..
Also in his library functions there is one "void callNumber(char* number)"
How can i use that?
These were working codes for me :
