BLE continuosly consuming Power even after I disconnect it.

[saiteja]

Hi,

I am working on NRF52 custom board with 3.7mA 27mAH battery, working on BLE app UART example SDK11 with SoftdeviceS132V2.0.

I made BLE advertise for 20 sec interval on button action, if I observe current across the Battery it is continuously showing 29mA. Once I connect the device with NRF Tool box app through BLE the current across the Battery increases to 35mA. After disconnecting the current reading is still 35mA and not dropping back to 29mA.

Could you please suggest me what to do so that the current drops back to 29mA.

Thank you in advance.

Have you tried removing all components not relevant to the nRF52? I am pretty confident that those 29mA currents are not caused by the nRF52. You can create a support case on MyPage if you want your schematics and PCBs reviewed with confidentiality.

Have you modified the NUS example in any way? It may be some events that don't get cleared and keep the CPU awake.
