Need Help getting Hibernate current lower
Using CYBLE-022001-00, EZ-BLE™ PROC™ Module. I am able to use the code provided with AN86233 (PSoC® 4 Low-Power Modes and Power Reduction Techniques) and get good results. However, the app note design contains almost no components. When I add a UART component (PSoC 4 SCB component, configured for UART). The Hibernate current goes from next-to-nothing to 200uA. I have tried the following APIs before entering Hibernate but nothing seems to make much difference.
I also switched the debug interface from SWD to GPIO.
My question is, what do I need to do before calling CySysPmHibernate() to get something more in the 200nA range and not 200uA with a SBC in the design?
Thanks in advance!
