Connect to your smart phone via Bluetooth and have SMS-like text messaging completely independent of the Internet or existing cellular infrastructure.Alternatively, or in the event that our app is for some reason no longer available in app stores, connect your smart phone to the WaveShark using a USB On-The-Go (USB OTG) cable and send your messages using any serial terminal app, such as Serial Terminal USB for Android. This method of use even works with your phone in "airplane mode" (cellular connectivity, Bluetooth, and Wi-Fi disabled).The WaveShark Communicators versatile connection options means that these devices can and will remain relevant long beyond the life of the iPhone or Android phones, which will ultimately suffer the same fate as the BlackBerry. The WaveShark Communicator was designed from the beginning to be a relevant communications device for decades, not years.
