CY5677 DeepSleep after Windows Reboot
When I have pluged in my CY5677 at Windows reboot, it falls into a DeepSleep mode and is irresponsive. No reply on the com port. "Unsupported device" in CySmart tool.
The only way I have found to get out of this state is to plug out/in the dongle.
When I do debugging in this state, the program continues in the CySysPmDeepSleep(void) routine after this line:
/* Sleep and wait for interrupt */ CY_PM_WFI;
I can discover trough state LED, that first, when I power up the windows machine, the dongle is in a ready/working state and then while startup comes into this state.
Any idea, how I can wake up the dongle from that state?
(I am using the official CY5677 firmware, BLE_4_2_Dongle_CySmart_256k.cydsn)
