Developing a project that uses GM862 Telit module, I have find out that the sms that are not received, goes to the service center, where they are stored and not always are being send back to us when we are reachable! Sometimes these are put in a black-list, other times these are just not being send! The problem is the GSM protocol, it seems it is like a bug! When a terminal reconnects to the network, the network does not notice the reconnection, therefore we must make our presence noticed.

Introduced the IperKEY project

Electronic key with microcontroller with auto-generation of the code and keys' programming. The project is downloadable, and comprises the version with 4 RELAYS (IperKEY), with 1 RELAY (Monozone), the key (KEY), key holder (INSERTER) and resistive version (RESKEY). To realize the IperKEY you must only make the inserter plastics and of the key following your design.
