GRX Controller 1.0 app for iPhone and iPad

The "GRX Controller 1.0" provides a wireless bluetooth controller for any Synthodeon GRX controller board or device containing such a board. The GRX provides power management and control (setting and reading power levels), cycle count, cycle duration and other features. This software allows the user to access GRX data and to set various GRX parameters.

Once connected, ad-hoc GRX commands may also be submitted.

You select a specific GRX-based device by entering its address (of the form XX:XX:XX:XX:XX:XX - included with any GRX-based when purchased) into the yellow field. The yellow fields is always active and you may enter the address value any time.

The app scans for the specific GRX unit address entered.

If an active device is found with that address a simple choice list appears (on a grey background) indicating its available via to connect via Bluetooth. You may connect to the device by tapping the address in the blue choice box.

Information about the communication between the App and the device appears in the large green window near the top of the screen. Data about battery life, ohms, etc. will appear next to their respective purple tags. To immediately update data tap the corresponding purple tag.

If no devices are present then a "Rescan..." message appears in red. Tap this again when a GRX-based device with the proper address is present and powered up nearby.

Once the connection is established information will be automatically uploaded from the device to the App.

The red field at the very top of the App screen may be used to enter GRX commands directly.

To enable automatic web site updates enter "upload auto 15" into this red box. This only need be done once.

If the blue fields (top field is user id, bottom field is password) are filled in the App will upload GRX data from the device to a supported web site.
