Well I just moved over from development on Telit modules where there are no APIs to speak of… just AT-command this, AT-command that. If you want to retrieve any type of data you have to send the command and literally write code to break apart the response string to pull out what you want. So when your app fails 3 weeks later it’s probably because you received an ever-so-slightly different response that doesn’t fit your code… (maybe the +CMGS count goes into double digits! oh no)
Anyways as far as I’m concerned SW is leagues ahead in this department. I am still thrilled when I come across functions like wm_strGetParameterString
