I am trying Deep sleep mode with the new FW (v1.2.27) of CYBT-353027-02.
The settings are as follows.
* I use CYBT-353027-02 EVB.
When entering deep sleep mode, LP_Mode pin is set to High.
(The current value of Module is several uA, so I think it is Deep Sleep.)
However, returning this LP_MODE pin to Low does not return the Module.
(The condition for returning is determined by issuing a BOOT Event from Module)
On the other hand, a similar test was performed with CYBT-343026-01 EVB.
(The LP_MODE pin is set to Active Low.)
In this Module, when LP_MODE is changed to Low, a Boot Event is issued and the original Active state is restored.
Why doesn't CYBT-353027-02 EVB return to active mode?
There is one more thing I found out.
I am checking on the evaluation board of CYBT-353027-02.
When releasing from Deep Sleep (HIDOFF) (transitioning LP_MODE pin from High to Low), the Boot Event was not issued from the Module.
In this state, pressing User Switch (SW3) issued a Boot Event.
This SW3 is connected to P9 (GPIO_6) of Module.
In EZ-Serial F / W, it is assigned to ADC0.
This pin looks like a wakeup.
My hope is that the EZ-Serial F/W will restart automatically even if there is no input to this P9 when it is released from Deep-sleep.
