now, the only problem that I have is that to set the number that the user will text as its new recipient. for example, I have texted "09454545565" and then sim900a module will use it as a recipient rather than the one that I included in the codeSounds like an interesting project. Where would you like help?
i haven't tried it because I don't know how to do itSo thi sis a programming problem? You'll have to post your code if you want help. Use the "insert code" option from the ... menu above the edit box.
let us say if I texted "UPDATE + NUMBER", the number stated in the text will be set as new recipient of the sim900a gsm modulei haven't tried it because I don't know how to do it
If your code recognizes a command called UPDATE, and parses NUMBER from the received string, converts NUMBER from a character string to an integer type (or the type of the recipient address), and uses that value as a parameter to a GSM call…let us say if I texted "UPDATE + NUMBER", the number stated in the text will be set as new recipient of the sim900a gsm module
