Texas Instruments eZ430-RF2480 manual Troubleshooting

5.Troubleshooting

5.1.Strange temperature values

If the temperature is much different from the expected value, this is because the temperature sensor is not calibrated.

5.2.Status of the connected dongle

It is possible for the status of the connected dongle to get out of synchronization if the dongle gets disconnected and connected rapidly without any delay in between. In this case the start/stop capturing data should be used manually to get the capture operational again.

5.3.More than one dongle connected to the PC

If more than one dongle is connected to the PC, make sure that the correct dongle is selected in the list of COM ports.

5.4.Connect/Disconnect other USB device on same PC

If any USB device is connected or disconnected while the eZ430-RF2480 dongle is connected and Capture data is active, the capture of data could get deactivated. In this case the Capture must be re-activated manually.

5.5.USB dongle not automatically detected when connected.

If the eZ430-RF2480 dongle is not automatically detected, try to remove the dongle and to connect it again. The system could be a bit slow on handling the detection of the dongle being attached or unattached so don’t do this too fast.

It is also recommended to first start the PC application and then to plug-in the eZ430- RF2480 dongle.

It is also possible to manually select the COM port from the drop down list. Search for device starting with “MSP430…” and select this one. Then push the “capture” button to establish the communication.

If still no success, it is time to check the device in the device manager. If the device drivers have been successfully installed, there should be one Composite USB device and one serial COM port.

Correctly installed devices should look like the screen shot below.
