BLE HRS PPK power consumption

[Pepam]

Hi,

I am starting with PPK. Tried some measurements on ble examples and looks like i am doing something wrong. I have aproximatelly 7mA during advertising. Am I doing something wrong with PPK? Also logging is disabled and using ble peripheral hrs example from SDK15.2 with pca10040. Please see attached print screen. All PPK switches are switched to DK option.

Thanks in advance

Hi,

If you are seeing ~7mA base current, there is either something wrong with the PPK/measurements, or the CPU is not in sleep. Have you made other changes to the examples than disabling logging?

I tested the precompiled HEX-file of ble_app_hrs example from SDK 15.2.0 (examples\ble_peripheral\ble_app_hrs\hex\ble_app_hrs_pca10040_s132.hex), and it gives an average current of around 600 uA:

Could you test this example, to check if the measurement setup is correct?

Best regards,
Jørgen

Hi,

Thanks for reply. I tried the same hex file and power consumption was the same as you had. So everything is okay now. Thanks. I have took a look at my code and I realized that I have added some code to turn on radio notifications which I think coused extra power consumption because of some fault with init.
