Hello Dinesh,

''Please note that we are using application which we have developed with references from SDK examples''

Most common cause of this high current (mA-range) consumption is the device remaining in debug interface mode. Did you perform pin reset to disable Debug Interface mood?

You can check on your example if some unused peripheral is being enabled (for example UART), TWI/I2C properly initialized or GPIO pins configured incorrectly.

I can't make specific comment without looking at the example or custom board design file. Could you share the example file?

Hi,

Please note that we are using application which we have developed with references from SDK examples.

This case has been observed for 1 of 100 devices and can not be reproduced easily.

At present we do not have graph from PPK2 but we can say that base current is above a.5 mAmp.

We wish to understand what are the possible causes for such issues.

Please share your views on the same.

-Dinesh

Hello,

Which example you are trying to run on the module? Did you try to run the example on nRF52832 and measure current?

Can I look at the graph from ppk2?
