Hi Hung,

Thanks for the answer.

[quote userid="2121" url="~/f/nordic-q-a/87487/pca10059-sleep-current/365916#365916"]Could you let me know how you measure the current consumption on the dongle ? With which measurement tool ? [/quote]

>> I am using ppk2 with connecting to J2 (TC2050-IDC) and the ppk2 gives power and not connected via USB port.

[quote userid="2121" url="~/f/nordic-q-a/87487/pca10059-sleep-current/365916#365916"]When you mentioned "sleep current" it's the current when the device enter which sleep mode ? Does it also do advertising ? [/quote]

>> There is no advertising. Even if I run the code like below, it keeps 15 uA without code related to BLE.

int main(void)

{

for(;;)

__WFE();

[quote userid="2121" url="~/f/nordic-q-a/87487/pca10059-sleep-current/365916#365916"]Please be aware that the dongle is not made to optimize power consumption because it's expected to connect to a PC anyway. [/quote]

>> Yeah, that's what I want to make sure. I was expecting the lowest current should be around 3~4uA but do you mean it could be higher for the dongle?

Thanks!

Please be aware that the dongle is not made to optimize power consumption because it's expected to connect to a PC anyway.

If you are planning to make a scanner running on PCA10059, I would suggest to have a look at the ble_central examples instead of ble_peripheral.
