I've got a project that operates as a web server providing data from a connected sensor. The devices gathering the data don't know its IP address so the ND+2 project also has a thread that broadcasts the device's IP address every 30 seconds or so.
This thing works flawlessly when connected via USB, but I'm testing it for remote usage, and when connected to a 9V battery power supply it simply fails to operate. I have no idea where to look to fix this, any help would be greatly appreciated.
So I had to look no further than the specs, and my multimeter. 7.5-9V power supply shown on the silk screen 7.5V-12V actual (at least from what I've now read). Power on the battery had dropped to around 7.41V, so there you go.
So the question becomes is there another way to power the device while I'm testing? I've got a 9V power supply, but it turns out that it is not regulated (thank goodness I checked it) and it was peaking around 13V. Should I invest in a regulated 9V power supply?
