Because PSoC 4 only supports BLE, the BR/EDR flag must always be sent with every packet. This is part of the Bluetooth specification.
You can remove the manufacturer specific data by unchecking the box on the bottom left.
Thanks for your response , if I unchecked the box for manufacturer specific data I wont have any advertisement data at all , I just wanted to get rid of the company name data. how can I then specify what data I want to have in the advertisement packet ?
The manufacturer specific data requires 2 bytes for company identification + the identifier that the data is manufacturer specific data.
An identifier is always needed, because the other device has to parse and understand the information within the advertisement packet.
You could use URI or set up a custom service and advertise it with the service data. But you will always have a little overhead.
What data do you want to exactly advertise?
You could use the function "CyBle_GapUpdateAdvData" to set it to whichever value you would like.
