Although I really need to focus on getting the DW code integrated into the current system, I could not resist checking the power situation.
I hacked a USB wire
and inserted my Fluke ammeter into the red wire. Could I somehow screw this up?
Then I configured the system simply to scan for BLE traffic continuously. The results are not encouraging.
I guess the next step is to do a lot less, and try to figure out where the power is going.
