ModTest Pro for Android

11 things about ModTest Pro

1. Return to the main display to send your poll and view the data (when in client mode) or accept and respond to data requests from a master device (when in server mode).

2. When in server mode, the app will wait for and respond to poll requests from a master device once a WiFi or BLE connection is made.

3. When you exit the Comm Setup page, WiFi connections will be established automatically; however, a manual scan must be initiated to find and select a BLE module within range in order to establish a Bluetooth connection.

4. It supports both TCP and UDP connections when using WiFi and it supports serial communication via many BLE modules equipped with Bluetooth 4 or higher that provide UART bridging capability.

5. After a successful Wifi or BLE connection, simply tap the Start Poll button to send your poll command (when in client mode).

6. Received data will also be shown in tabular form when in client mode and communication events will be shown when in server mode.

7. The app also features a User Data Mode that allows you to enter a complete poll string independent of any particular protocol.

8. The Comm Setup view allows a number of addressing, timing, and communication mode parameters to be configured.

9. It also supports the GSI protocol which was developed in 1985 and was the first tank gauging protocol to use standard RS232/RS485 serial data communication.

10. It supports a wide range of MODBUS functionality, including the ability to operate as a client or server (master or slave).

11. This allows transmission of special ASCII data polls or any MODBUS command that is not natively supported by the app.
