    CYBT_483039_EVAL No bluetooth signal


      Hey guys, I recently purchased the CYBT_483039_EVAL board and I went through Wiced Studio. I made sure to pick the 20719-B1_Bluetooth package and I have the Make Target window open. I was able to build and the device was found in the console log. I see the device led's start up which indicates that the application is being downloaded. I have UART open and I can see the log of the events and I've traced the the outputs to the init function in the code. They all line up. I then try to scan for the device and nothing turns up, is there something else that must be done???

          You must install the below platform files in order for your eval board to work.


          WICED Studio: Platform Files for CYBT-483039-EVAL – KBA223747

            Hi ChNi_2249236,


            You can refer Programming an EZ-BT WICED Module – KBA223428 for detailed programming process. Also, as BoonT_56 referred, add the platform files in your directory.

            Let us know if this works for you.

              Yes,  I have installed the files (they came with Wiced Studio 6.4)

                  I did not know that you were using WICED 6.4. There is a glitch in WICED 6.4 with CYW20719 based modules. Our software team is working on this. BugS Report:  WICED6.4.0/Missing files

                  Till then please use WICED6.2.1 referring to above KBA you mentioned.

                  Apologies for the inconvenience.!
