    Programming a device with BLE 4.2 USB Dongle

    user_3880456

      Hello all,

       

      I have the following products:

       

      • CY8CKIT-042-BLE-A Bluetooth® Low Energy 4.2 Compliant Pioneer Kit
      • CY5677 CySmart BLE 4.2 USB Dongle (BLE Dongle)
      • A chip on a PCB that I got from a company, which uses the same processor with the CY8CKIT-042-BLE-A

       

      I have 2 questions:

      • First, what is the USB dongle used for?
      • Second, how can I program that chip on a PCB? Do I need a MiniProg3 or can I do it with the USB dongle? The dongle has 10 pins that are named PRoC BLE external programming header. If so, how should I connect the dongle (or MiniProg3) to my chip on PCB? Any help is much appreciated. Thanks in advance.

       

      Respectfully,

      Alperen Görmez

          Q. What is the CY5677 Cysmart dongle used for?

          A. The dongle is used to emulate a BLE host on the computer and allow you to communicate with the CY8CKIT-042 kit configured as a BLE peripheral. You can look at the different parameters/characteristics/data etc. in the CySmart Software tool. The dongle can't be used to program the chip on the custom board. The 10 pin header on the dongle is used to program the PSoC 4 chip present on the dongle only, if programming through USB (via Kitprog) is not possible. It cannot be used to program any external boards.

           

          Q. How can I program the chip on the custom board?

          A. You will need to use a Miniprog3 for programming. Please refer to the section Physical Layer (Page#13) of the following document for the hardware connections between the programmer and the target device: http://www.cypress.com/file/409516/download
