CYW20706, wiced_sleep_config, bt_wake, host_wake

[adam]

Hi there, 

IDE: modustool box version 2.4.0

Chip: CYW20706

Project: LE_Hello_Sensor

I want to control Pin BT_DEV_WAKE(GPIO36, WICED_P36) as a IO output Pin, 

but when I call wiced_sleep_config (TRUE, WICED_WAKE_GPIO_ACTIVE_LOW,  WICED_WAKE_GPIO_ACTIVE_LOW); in APPLICATION_START()

the PIO36 is difficult to control output HI, output LO, 

I am confuse about is  wiced_sleep_config () limited the control of PIO36?

so, I want to set  wiced_sleep_config (TRUE, NULL, NULL), 

but build project error. 

I don't know any step go wrong.

Hi, 

If you enable sleep mode using wiced_sleep_config and configured the Dev_wake and Host_Wake active modes, then those pins will be under the control of the FW which controls the sleep modes. 

By the way, there is a bug in the current SDK in configuring low power mode for cyw20706. We are internally debugging and fixing the issue. The fix will be available in the upcoming SDK.

Thanks,

Hi @DheerajPK_41 , 

So if I set Dev_wake and Host_Wake output hi, 20706 will not go to sleep mode, am I correct ?

thanks,

Adam

Update:

Based on the below parameter, we can wake up the device or host. We should define the polarity in wiced_sleep_config_t.

sleep_config.device_wake_mode
sleep_config.host_wake_mode
