Hi, I'm using nRF52 DK to develop and PPK v1.1.1 with Power Profiler app on nRF Connect v3.3.1 to measure current.
1. I see a lot of posts referencing the firmware on the PPK. I have no idea what firmware is on my PPK now. When I try to program my nRF52 DK with the PPK, it seems to write to the nRF52832 on the PPK because it's connected to P20. Yet, even with the blinky example written to the PPK, I can still measure current on the app. The steps I take now to update my DK firmware are:
a. remove the PPK
b. put the jumper on P22 on the DK (SB9 is cut and SB11 remains disconnected)
c. in SES, download my app to the DK
d. put the PPK back, remove the P22 jumper
Is this correct? Do I need to remove the PPK every time? And what firmware should be on the PPK nRF52832?
2. I used ble_app_uart_c_pca10040_s132 as the starting point for my code. I'm measuring on the PPK. My system has both Central and Peripheral
Peripheral --
I saw a bunch of other posts of negative current, but couldn't find a solution.
On the PPK, SW2 (DUT Select) = DK, SW1 (Power select) = DK and COM = DK. no USB.
On the DK, USB is connected, no coin cell battery, SW9 is open and SB11 is open.
Thoughts? Thanks in advance.
