Moreover, the acquisition time of a GPS position willhave to be taken into consideration.Using the RESET does not restore the factory parameters.7.7 WatchDogThe Hardware WatchDog function allows the surveillance of the modem software activity: the Softwaremanagement of the WatchDog is implanted in the embedded application by default. In the case of adevelopment (EGM) it must be implanted in the embedded application of the final customer.If the software activity is interrupted, the WatchDog component starts a hardware Reset.The WatchDog function is active only if the SIM card is present. That’s why, it is imperative to remove theSIM card during a Firmware updating.
