Hello,
I used this guide to add FOTA over BLE for nRF5340.
However, the power consumption rises significantly from 20uA to 2mA. What should I do to optimize the power consumption?

Hello,
Which SDK version are you using here? Could you brief the issue a little more? Like, when exactly are you seeing this significant rise? Is it during the DFU process or after updating the firmware?
I recommend following our Nordc Developer Academy tutorial for doing a BLE FOTA. See the section FOTA over BLE.
Kind Regards,

Hi,
I'm using SDK 2.5.0.
In our system, the nRF5340 collect analog inputs then send data through BLE every 30 seconds. Normally, the nRF540 sleep for 30s, wake up, acquire and send data, then go back to sleep. The average power consumption was about 10-20uA.
When we enable the FOTA through BLE, the power profile shows a steady current and we get about 2.17mA average current. It seems like the nRF5340 never goes to sleep.
I've also followed the tutorial from Nordic Developer Academy.
