I have an “IoT Long Range Wireless Vibration And Temperature Sensor” communicating with my device via the 900HP-S3B long range wireless mesh modem with USB interface.
I was running the sensor from the 2 AA batteries without issues. I purchased a 12VDC supply and switched the slider to external power in the sensor. After that I completely lost connection to the sensor, I cannot get any data. I switched back to battery power but I still cannot get any data. In either case (external or battery power), when I press the configuration button I see the red LED light up, so at least some part of the sensor is getting power.
I tried to reset to factory settings but I still cannot get any data back. Steps to reset I followed are this: 1) press config button, 2) press reset button for a second or so, release reset button, 3) keep pressing config button for more than 15 seconds, then release config button. I also tried pressing reset, then pressing the config button, keep it pressed while I released the reset button, and kept holding the config button for more than 15 seconds.
Do you have any troubleshooting suggestions or any way to get the sensor to work again?
