Sorry for this being so vague but I'm trying to understand the use of GPRS in the following context:
Small amounts of data to send e.g. could all fit in one SMS
Restrictive power consumption requirement
Possible need to contact the GPRS enabled unit remotely
So the question is, why bother with GPRS when SMS would do the job nicely and save on power. Also, to force a connection to the GPRS unit, surely you would need to program it with a specific date/time to wake up or, alternatively, send an SMS to make it dial out and create the connection.... or am I missing something?!
