Please program your board with the BLE_Findme code example available in PSoC Creator code examples section to check whether there is some issue with the hardware you are using. This code example will work flawlessly.
If the above code example works, your hardware is fine. Have you gone through BLESS deep sleep code example? If yes, please check whether your firmware flow is according to the flow in example project.
If you have followed the flow and still if you are seeing issue then, please comment the events in Eventhandler function and check which event is causing the issue.
If possible please attach your project here. We will check it at our side.
Good morning GaneshD,
let me apologize for my delayed answer but, I was delving on this very disturbing situation of CPU stuck.
Finally I managed to find out the reason for CPU stucking. Actually there were 3 (yes three!!) reasons:
1. A forgotten CyDelay(20). It seems that 20 ms delay is not permittable for BLE in wake up from Deep Sleep mode
2. Wrong Power CPU handling at CYBLE_BLESS_STATE_EVENT_CLOSE state
3. Writing on FLASH (the FLASH clock is gated at Deep Sleep)
I hope my flaws could be valuable for other developers
