在DS功耗PS device

Hi:
I use the DSPS device SDK. Set sleep_state_t app_default_sleep_mode = ARCH_EXT_SLEEP_ON in the user_config.h file, define CFG_MEM_MAP_EXT_SLEEP and set adv interval 3s.But the device always has an offset value approximately equal to 2.3mA and never reach the sleep current of 2uA or less. The DA14580 device has got less 2 uA with SDK3.0.8. What wrong with the DSPS device SDK.
Thanks.

Hi fn654,

Hi fn654,

All of example is the SDK (except of the ble_app_sleepmode example) never fall into permanent sleep, all of the examples are sleeping and waking up periodically in order to advertise or keep a connection alive. That is the case with the DSPS as well, the device never fall into permanent sleep but it sleeps and wakes up periodically, in order to measure the sleep current you will have to set an advertising interval that large in order for your DMM to be able to measure the lowest power consumption. Please check in the tutorial section the Tutorial 4 : Conifiguring sleep mode on the DA1458x.
