Nano BLE Sensor serial wont work....

Before you start with the " read other ..blah blah..." I read it all and tried it all. This thing won't open Serial port since the port changes. reset wont work. Just puts me at square one. Last try to to get this to work before it goes back to Amazon. Disappointed in Arduino for putting this thing out. I have used several other board with no issue. No point in putting up error since everyone knows what its doing. Just hoping someone out there made some break through getting this garbage to work. SMH....
