IM using SIM800L to send data. i just figured how to send data through gprs but i have trouble with sending sms .
when i send message on the other side i get nothing or some kind of Chinese characters (like this: 瑨楳猠瑥獴浳) .
here is my code:
sim800.printn("AT+CMGF=1"); //return ok delay(100); sim800.println("AT + CMGS = \"50002333126507\""); return > delay(100); sim800.print("Hello, world. This is a text message from an Arduino Uno."); sim800.write(0x1A); sim800.write(0x0A); delay(100); sim800.println();
Also i tried AT+CSCS="GSM" and "IRA" before CMGS
any one knows whats wrong?
