2.1.2.2 Issues & Solutions

Changes made to HEOS user account, through HEOS app will not reflect through CLI until the controller is restarted. Ex: Adding or

removing music services to HEOS user account, through HEOS app will not reflect in get_music_sources command response until the

controller is restarted.

Solution: Controller needs to re sign-in to HEOS account to reflect changes made through HEOS app, with out restarting

the controller. So, in addition to performing HEOS account sign-in as part of driver initialization process, it is highly

recommended to provide sign-out and sign-in option through end users UI screen. End user need to re-signIn when he

adds/removes music service through HEOS app.

2.1.3 Miscellaneous

Controllers can add custom argument SEQUENCE=<number> in browse commands to associate command and response. This is

possible because the 'message' field in the response packet includes all the arguments sent in the command. Please let us know if

you need additional custom argument other than 'SEQUENCE'. This is to avoid accidentally using HEOS command arguments for

special purpose.

Maximum number of simultaneous socket connections supported by HEOS speaker is 32.
