So I am tryin to feed my fona800 a string that contains the phone number I want to dial. I am obtaining the numbers through a count of a rotary dial. Inputs come in and are stored in an array. I convert the array values into a single long number and then use sprintf to convert them to a string so I can feed my fona. However, the value of the string it returns is only 5 digits long and I don’t know why.
The attached screenprint of the serial shows 1 dialed ten times and the resulting sprintf output. Any help is appreciated.
