RESET*-GSM is used to reset the GE863-PRO3modules GSM/GPRS engine. Whenever this signal is pulled low, the GSM/GPRS engine is reset. When the device is reset it stops any operation. After the release of the reset the GSM/GPRS engine is unconditionally shut down, without doing any detach operation from the network where it is registered. This behaviour is not a proper shut down because any GSM device is requested to issue a detach request on turn off. For this reason the Reset signal must not be used to normally shutting down the device, but only as an emergency exit in the rare case the device remains stuck waiting for some network response.

The RESET*-GSM is internally controlled on start-up to achieve always a proper power-on reset sequence, so there's no need to control this pin on start-up. It may only be used to reset a device already on that is not responding to any command.

NOTE: do not use this signal to power off the GE863-PRO3GSM/GPRS engine. Use the ON/OFF*-GSM signal to perform this function or the AT#SHDN command.

* this signal is internally pulled up so the pin can be left floating if not used.

If unused, this signal may be left unconnected. If used, then it must always be connected with an open collector transistor, to permit to the internal circuitry the power on reset and under voltage lockout functions.
