PSoC Creator was developed by Cypress to enable development on PSoC devices and continues to support PSoC BLE and PRoC modules. Likewise, WICED Studio was developed to support the Broadcom Bluetooth and WiFi devices. This continues to be the case and so,if you are looking at a device that starts with CY8C* or CYBL* then you need to use PSoC Creator and if you have a CYW* then you have a WICED device and need WICED Studio. We have a long-term strategy to simplify tool selection for these functionally related devices.
ok, let me rephrase the question:
If I am starting a new IOT project, and I have no previous experience with WICED or PSOC, then can you tell me what advantage there is with WICED devices compared to PSOC. Is it just the development environment? Is the WICED environment more suited for cloud type interactions?
Does WICED offer flexibility of analog/digital configurability like PSOC/Creator?
That is quite a big question. I'll try to direct you. I am sure we have something you can use!
If you need WiFi then you need to look into WICED devices. We have 802.11 WiFi devices with an integrated application processor as well as radio chips that you can connect up to a separate MCU. You can also get a module that has done this all for you (and certification).
If you need Bluetooth then you can get a WiFi/BT combo device or a Bluetooth-only device. There are WICED and PSoC solutions here. PSoC is a configurable SoC and we have BLE-enabled versions of that (no WiFi). If you like the idea of a very flexible MCU and are not using WiFi or traditional (aka classic) Bluetooth, then this could be a solution for you. The WICED Bluetooth solutions also support classic Bluetooth and both BR and EDR data rates.
I recommend you take a look at this page. It is a great starting point to find out about the IoT solutions.
