Hi,
We are developing on nRF52832 with NCS v2.9.2 (Zephyr) on a custom PCB (LDO, no DCDC, 32 kHz RC).
On the same hardware, our nRF5 SDK firmware shows much lower average current than our NCS / Zephyr build.
To isolate the issue, we tested the official bluetooth/peripheral sample on the same board with PPK2. The average current is still around 2–3 mA while advertising (not connected), which is close to our Zephyr application and far above our nRF5 SDK results.
Could you advise how to reduce power on the official BLE peripheral example for nRF52832? For example, recommended prj.conf settings, power management options, or any known configuration issues that would explain this level of current?
Thank you.
