If you look at the S110 specification, chapter 8, there is a advertising power profile. If you calculate that with a 25 ms interval, you can see if that matches your measured current. With 25 ms it should be around the area of 1 mA avg, depending on the length of your advertising packet.

Usually, your debugger interface is active if you see 1.2 mA. turn the board off and then on again to return to normal run mode.

Hi Hakon,

When i erase complete nordic flash by using nrfgo . And i measure current it is about 2.58 mA.

i did with power reset also ,current is same.

Why current is too much.

Hi Hakon,

Thanks For your reply.

Our advertising interval=25 ms

Can you say what is debugger interface and power -cycle.

Hi Balaji,

My first though is: That current measurement indicates that the debugger interface is still active. Try doing a power-cycle and then measure.

However, the current consumption will vary depending on your advertising interval. What is your advertising interval?
