Can you please let us know which module you tested? If the project is working on PSoC chip ,it should work with PRoC as well.
I'm testing the "BLE_OTA_FixedStack_Bootloadable and Bootloader projects. When I attempt to do an OTA update from CySmart, I select the firmware image of the bootloadable project. When I try and do the update, it halts and fails at the "Authentication" step. I have made no changes to the example project except configuring the output pins to my board.
Please make sure the security settings in your project matches with that of the CySmart.
In Cysmart, click on 'configure Master settings' -> security parameters - check whether the security level matches with that of your project. Else change it and test again.
