Hi,
I am using Murata 1LD and thinking what is the best way to lower power consumption during ble advertising ( also how to do that ).
I am using wiced 6.4 with murata 1LD 6.4 platform files.
My project is base serial gatt with additional 2 tasks that I created that do some stuff and go to sleep
while(1)
{
expected_data_size = COMMANDS_BUFFER_SIZE;
/* get incoming data size - if as expected - recieve data */
wifi_bufferSize = wiced_uart_get_recieve_buffer_size(WIFI_UART);
if(wifi_bufferSize >= expected_data_size )
{
.. code
}
wiced_rtos_delay_milliseconds(100);
}// end while
How can I put device to sleep and still advertise and when ble connected to exit sleep mode ?
Any Ideas?
Thanks!
David

Hi David,
Please refer to API wiced_bt_dev_set_low_power_mode.
You may refer to the snip/bluetooth/ble_hello_sensor/ble_hello_sensor.c for usage. This API is sufficient to let the device enter low power mode.
Please check if this will help your requirement.
Thanks,
Anjana

Thanks!
It really helped.
Another questions
1. What is the best way to turn off Wifi & BT chip ?
for WIfi - host_platform_power_wifi(WICED_FALSE); - it turned off the wifi power pin (WWD_PIN_POWER)
How can I turn off Bluetooth ? I tried to use WICED_BT_PIN_POWER but it is not working...
2. I tried to turn everything off by lowering rst pin but it still consume 2mA . is there a better way ?

If some need it - if you want to turn off 1LD withou power consumption use this code:
wiced_bt_start_advertisements( BTM_BLE_ADVERT_OFF, 0, NULL );
RTC_DeInit();
__disable_irq();
wiced_bt_stack_deinit();
wiced_deinit();
platform_gpio_output_low( &m_BT_PowerPin );
platform_gpio_output_low( &m_Wifi_PowerPin );
/* Select Standby mode */
PWR->CR |= PWR_CR_PDDS;
/* Set SLEEPDEEP bit of Cortex System Control Register */
SCB->SCR |= SCB_SCR_SLEEPDEEP_Msk;
__WFI();
Reset or wake up pins turns it ON

HI David,
You are correct.
There is no direct API for turning OFF wifi & BT .
Rather you can stop advertisement or connection on BT side to ensure there is no BT activity. And deactivate other necessary components.
