@bide, thanks for the detailed questions.
I’ve moved the EM38 to a foot away from the computer (on the back of the turned-off ATV) and it had no impact. In this format, my body was potentially between the RS2/EM38 and the computer, but otherwise there was nothing in between. All 3 pieces were on the ATV with the EM38 on the back of the ATV, the computer on the front, and the RS2 on a pole on the ATV.
It has occurred to me this is an issue because the bluetooth dropoff happens primarily when moving on the ATV. When I’ve tried carrying all 3 elements on my person or left the equipment running while on the turned-off ATV and dropouts did not happen.
That being said, turning on the ATV and letting it idle does not seem to cause the issue. As well, once the bluetooth has dropped often turning off the ATV or moving the equipment around does not allow it to find the EM38 via bluetooth.
This is not a variable we thought of testing. I will see if this affects the issue.
You are correct on the ordering of proximity. The metal chassis of the ATV is between the EM38 and the computer.
I will also download a bluetooth RSSI app and check the signal strength.
Lastly, I have attached a photo showing our old wired setup, but it should help with visualization. With the bluetooth setup, we have the computer in the bin on the front and the RS2 on a pole on the back of the ATV. Everything else is the same.
