Power consumption issue
I've spent some hours on my CY8CKIT-042 BLE and I'm now checking the power consumption of my project. I applied the AN92584 application note to my code but my measurement on J15 gives a few mA when connected.
I tried the "BLE connection example" that is attached to the application note, but I still have 1690uA consumption when connected, so in deep spleep mode. Looking at the power calculator I should have less than 20micro Amp consumption, and I measure 100 x more??
I tried on the Proc BLE also, but have exactly the same 1.7mA consumption.
To be sure I made the measurements without the pioneer baseboard by directly applying power between VDDD and GND on J2 connector, but I did not make any difference.
Do anyone have an idea about what to do to find the problem.
