DA1469x Sleep Mode Implementation - Needed Example

Hi Zinal,

I would recommend you first checking theDA1469x Power Consumption TutorialandDA1469x Wake up controllerSW Example from the DA1469x support page.

NOTE : Changing the device selection from DA14580 to DA1469x in the initial post.

Hi Zinal,

请看看pm_sleep_mode_set () API。This function should be used in order to set the device into her desired sleep mode. Would you like to stop advertising and put it in permanent sleep mode? If the device is advertising, the is will go into sleep mode between adverting intervals. All the SDK BLE examples configures the device into extended sleep mode.

Thanks, PM_Dialog

Hi Zinal,

TheDA1469x Wake up controllerSW example is demonstrating similar functionality. Which SDK project are you using? Does the device advertise? If yes, you will have to stop adverting and put it in sleep mode. Please keep in mid that the device can go into sleep mode between advertising or connection intervals and wakes up automatically by the BLE timer.

Thanks, PM_Dialog

Hi Zinal,

If you are interested in testing the sleep mode, I would recommend using the SDK examples.

The ble_gap_adv_stop() should be used in order to stop advertising. If advertising is successfully stopped, the application will receive a BLE_EVT_GAP_ADV_COMPLETED with status set to BLE_ERROR_CANCELED. So, you should setup a timer and stop advertising after a predefined amount of time.

Please refer to ble_adv example of the SDK and see how the BLE_EVT_GAP_CONNECTED and handle_evt_gap_connected are handled in the for(;;) loop. You should do the same for the BLE_EVT_GAP_ADV_COMPLETED.

static void handle_evt_gap_adv_completed( ble_evt_gap_adv_completed_t *evt) { pm_sleep_mode_set(pm_mode_extended_sleep); } case BLE_EVT_GAP_ADV_COMPLETED : handle_evt_gap_adv_completed((ble_evt_gap_pair_req_t *) hdr); break;

Thanks, PM_Dialog

Hi Zinal,

I am trying to say that in order to go into hibernation or deep sleep you should not have any BLE activity, so you should stop advertising and configure the device into sleep mode. If there pending interrupts, then the system will fail to hibernate. ‘

I have explained you how to stop advertising and then put the system into hibernation.

Please try to stop advertising in the ble_adv example, and configure it into sleep mode.

You should have to measure the current consumption.

Please check the following exampels :
