Hi I just bought b4A four days ago and a newbie and this forum is the only way I could get help. I am having a problem compiling the codes..... the error is as follows:

B4A version 4.30
Parsing code. 0.02
Compiling code. Error
Error compiling program.
Error description: Unknown member: isinitialized
Occurred on line: 47
If Serial1.IsInitialized = False Then Serial1.Initialize("Serial1")
Word: isinitialized

At first I thought it was the library problem but it isn't. I got the libraries enabled:
core (version 4.01)
RandomAccessFile (version 1.30)
Serial (1.20)



B4X:
#Region  Project Attributes
    #ApplicationLabel: btControl
    #VersionCode: 1
    #VersionName:
    'SupportedOrientations possible values: unspecified, landscape or portrait.
    #SupportedOrientations: unspecified
    #CanInstallToExternalStorage: False
#End Region
