Hi,
I've been trying to use the nordic power profiler v1.1 with my nRF52 development board to figure out how much current is consumed during operation.
I used the power profiler app in nRF connect PC (latest update) to view the output and got something like this
I measured the average current during advertising to be ~ -31.56uA, average current during connected to central device to be ~ -31.48uA and average current during sleep to be ~32uA.
I even tried using the ppk.py (latest version) which gave a graph that was in the negative region with average current that matched the above results.
It looked like this-
I did not perform the "cut sb9 track" + "soldering sb12" steps since I was told by a co-worker that it wasn't required and also I am not very knowledgeable about soldering/unsoldering and didn't want to damage the board . Could this be the reason for these results?
Please suggest any other reasons that could be causing this.
Also, if there is a step by step guide to performing the "preparing nRF52 for current measurement" , as a video it would be very helpful.
Thank you.
Edit: Since my end goal is finding the battery life for a custom board powered by a 3V coin cell, would using this configuration eliminate the need for soldering/cutting tracks -
If so, is there anything else i can use instead of the 10-pin flat cable between j-tag and the power profiler, say jumper cables?
