Finally an embedded application!
Thanks to the technology used inGSM Bulk, it is
possible to build custom applications to satisfy any
particular need.
We can carry out applications working independently
from your device, taking care of the "communication"
part only.
For example, we can send an SMS when a change of
a TTL input is detected or manage a password
exchange without modifying a string in your
application.
