I cannot communicate with my wireless sensor. My USB modem powers up and the TX and RX light blink, but then just the USB light stays on. I’ve tried the USB modem on a Raspberry Pi3 (using it with Node-Red) and on a Win7 machine (Alpha Station to setup the sensor). On both systems, the modem RX and TX lights do not light up when I power up the sensor (via battery or external 12V power supply). I moved the power jumper left to right and held the CFG button, while continuing to hold the CFG button, I’ve pressed the Reset button and continued to hold the CFG button for various amounts of time, 2, 4, 6, 15, 20, and 30 seconds. The USB modem doesn’t change. Antenna are attached and the sensor is fairly close to the modem. I’ve verified on the win7 machine that I am using the correct Com Port. At this point in time, I feel the sensor or the modem do not work.
