Hi! I want to use the PPK2 to measure the power consumption of my feather. Some problems though: My feather is soldered to a shield custom made for prototyping. The connectors are exposed though so I can maybe wrap a jumper cable around a connector, which I tried. I did this and connected the BAT and GND of the feather to the VIN and GND of the PKK2 but the output I see is so small it cant be correct. Also I see no difference if the LTE is sending or not. I am using a battery to power it, however, to get it started I first connect a usb (when battery is plugged in to feather), reset the device and remove the usb connection.
How many things am I doing wrong and can it be done right?
