Welcome in the forum.
Can you post your complete project, so that we all can have a look at all of your settings? To do so, use
Creator->File->Create Workspace Bundle (minimal)
and attach the resulting file.
You need to disable debug capabilities which draw some mA. in .cydwr system tab, set Debug to GPIO.
I am using AN86233 - PSoC® 4 - Low-Power Modes and Power Reduction Techniques .
I have modified project for Psoc4 -BLE and trying to do the same but still I am getting 1.17 mA current in Deep Sleep mode.
But as per the datasheet we should get it in uA.
Debug is set to GPIO and ICO - 3MHz
The ECO is enabled. That should be the reason for higher current consumption. Try disabling the ECO using the API CySysClkEcoStop() and then measure the current. When BLE is integrated, you need to use BLESS low power and device low power codes. You can refer AN92584 for more details.
