@mfalkvidd said in Problem getting BMP180 to show correct readings.:
@royson84 the adafruit description says
connect the VIN pin to the 5V voltage pin
and
Vin: 3 to 5VDC
so I think any voltage between 3 and 5V will work.
Ok. Gonna give it a shot tomorrow with a Pro mini and see if that gives any different results.
@sundberg84 I do have a multimeter, but haven't used it in ages so I'm not sure how to honestly. =D
On the PCB I made all the connections by soldering but I have put that aside for now. Figure I must find out what I'm doing wrong with the radios first. Now when I'm trying to make a new serial gateway I've done so both with some soldering and some duponts.
Today, as a bit of a last restore, I'm gonna remove my radio from the ethernet gateway, which doesn't give me any failures in debug, and try the same setup with that. If that doesn't work, well..hehe.. Stuff is gonna break 
I really appreciate all your help and suggestions guys!!
