I have a Vibration/temperature sensor and a Long-Range Wireless Mesh Modem with USB Interface. I am able to connect the modem up to my computer and output the data in the LabVIEW utility downloaded here: https://github.com/ncdcommunity/Industrial-IoT-Vibration-Temperature-Sensor
When I try and connect to the sensor through Node-Red I get a warning that says failed to connect and the output terminal looks like:
16 Aug 15:11:57 - [info] Started flows
error: ‘Request timed out without response’,
original: [ 8, 7, 73, 68 ]
When troubleshooting I first tried to download XCTU to configure the modem, but XCTU could not find the modem.
Another weird quirk is that the Rx light on the modem is never turning on, even when the reset button on the sensor is hit the Rx light never flashes.
This makes me wonder if it is an issue with the COM port, which doesn’t totally make sense since I was able to receive data in the LabVIEW utility.
Any help or advice would be appreciated!!
