SW Information

- Chipset & EVK : CYW20706 & F1DC2076 EVB (made in F1media)

- WICED SDK version : WCIED 6.2.1

- Test application : SPP

 

Test

  1. i have changed the transport to UART
  2. and i added the "wiced_sleep_config( WICED_TRUE, WICED_WAKE_GPIO_ACTIVE_LOW, WICED_WAKE_GPIO_ACTIVE_LOW );" to "end of APPLICATION_START()"
  3. and i was set the "BT_DEV_WAKE" pin to high
  4. and then current is lower than about 4 ~ 5mA
  5. "BT_HOST_WAKE" is keep to high, not changed to low
  6. i have tried to connect from phone to CYW20706

 

the "BT_DEV_WAKE" and "BT_HOST_WAKE" is as below.

the result of test is CYW20706 can not received the connection.

it seems that entered sleep mode, but can not wakeup.

i found that CYW20706 can be wake by BT Radio as below, but it was didn`t.

can CYW20706 wakeup by BT radio? why can not wakeup the CYW20706 by BT radio?

Hi,

 

Could you please try using it as a standalone device and check the low power mode? Meaning, try using an external GPIOs instead og BT_Wake and Host_wake pins. General purpose GPIO can be configured and these interrup shout wake up the device. 

BT Activity can also wake up the device. But I hope it will be in effective only after the connection. Before the connection the BT Device has to initiate the BT activity (Eg. using a timer or so) then it will wake up from sleep.

Thanks,
