After disconnected, why does electric current increase ?

[hiroponie]

Now facing the problem "After disconnected, the electric current increases"...

I think softdevice is working hard even after disconnected when connecting once. Could you tell me how to back to the calm state of softdevice by sd function(s)

Is there any the way to close this problem except sd reset for real.

Thanks in advance.

1. How much does the current increase?
2. Does your application continue to work as expected even after the current has increased?

[hiroponie]

1. twice
2. yes

1. And how many micro or milli amperes would that be? The value might give us a clue about what is going on.

[hiroponie]

About 5mA to 10mA, appreciate your quick responses.

Sounds strange.

• Do you transfer a lot of data? That would explain ~5mA during connection. The radio and occasional CPU activity will drive the current up, but assuming the CPU is sleeping in between BLE event the average current is not as high as if the CPU was on continuously.
• 10mA might sound like the CPU is running continuously and that you don't use the DCDC converter. Is that correct?

1. Have you debugged your code to see what, if anything, your application is doing after a disconnect? Maybe it is stuck in an error handler, or waiting for some sort of event for a peripherals?
2. What, if any, peripherals do you use? UART, ADC, etc.?
