I've go this code as of the moment #include <SoftwareSerial.h> SoftwareSerial mySerial(7, 8); String numstr , message , inbox; void setup() { Serial.begin(19200); mySerial.begin(19200); //Default serial port setting for the GPRS modem is 19200bps 8-N-1 mySerial.print("\r"); delay(1000); …

It is your first post and you managed to put your code inside of code tags - well done! Unfortunately that is where the compliments end. You haven't included the serial output that you hinted at, although the code doesn't seem to be writing any anyway. The code you posted doesn't compile; a #incl…

You haven't really explained what you expect to happen. In any case, the random binary data you see towards the end of each output line is due to the fact that you are not null terminating response. This should probably fix that: char response[256]; // ... while (mySerial.available() != 0 && i <…

I just need the serial to not output the garbage values then I'll substring the message contents

I have here is my current code #include <SoftwareSerial.h> SoftwareSerial mySerial(7, 8); int power = 9; int val; String numstr , message , inbox; void setup() { Serial.begin(19200); mySerial.begin(19200); //Default serial port setting for the GPRS modem is 19200bps 8-N-1 mySerial.print("\r"); …

if ( i % 31 == 0 && i > 0 ) { Serial.flush(); mySerial.flush(); } Why are you flushing the output buffers ? while (mySerial.available() != 0 && i < 255)Do you always get 255 chars returned ?

k5nn: PS. posted at the wrong one apologies What does that mean? Are you still looking for help? Maybe have a look at the examples in Serial Input Basics - simple reliable ways to receive data. The only limit to the number of characters is how much SRAM you have available. ...R

Robin2: Are you still looking for help? I was supposed to post this at programming questions cause well the nature of the question is programming related
