Our client want to do function via Bluetooth Core Specification 4.2 or above. I think cybt-343021-01 is meet 5.0. Then I see below information in WICED Studio Developing Custom Applications with BT Designer spec. If I use WICED to generate the code, will it be any problem? Can 4.2 requirment be meet?
There will be no problem to create your code meeting BT4.2 spec, WICED will support it.
