Hi,
I'm following the guide Tutorial 5 : configuring sleep mode on DA1458x.
When I do my messurement as they do in the tutorial I get 2,4 uA instant current and around 3,2 uA as average current.
I use basic development board 14580.
What SDK is used in the tutorial?
Is there some more parameter that has to be set?
Best regards
Viktor

Hi dorfmundA,
SDKused is the 5.0.3, besides from what the tutorial indicates there is no additional configuration, please bare in mind to remove all unnecessary jumpers in order to avoid any leakage which is the most possible explanation of what you see.
Thanks MT_dialog
Hi,
Okey. Is there any differens if I load project prox_reporter to SPI flash and boot up and then remove all jumpers?

I have problem to get the DA1450 to get to sleep mode if I do as in the tutorial. By first click the debug button in Keil and then click it again.
Best regards

Hi dorfmundA,
No, there should not be any difference if you remove all the jumpers. The 2.4uA that you get has a result is approximatelly 1uA offset and that doesn't mean that the device doesn't go to sleep (the power cosumption when awake is measured in a few milliamps), i assume that the extra offset that you get has to do something with your instrument setting (perhaps the averaging interval is too large and in the result it accumulates values from when the device was awake during the advertising interval), you can try to repeat the measurement with the ble_app_sleepmode project in extended sleep that falls to sleep permanently until a button is pressed. But in no case the 2.4uA that you see means that the device doesn't go to sleep. Also it could be an extra current offset from the pcb of the basic kit that you are using.
