Question about HCI_EXT_PROFILE_SUBGRP processing

Chris Norris

Good evening,

I am wondering if TI can provide some additional background on the purpose of HCI_EXT_PROFILE_SUBGRP.

I have an application where I need to get and set parameters in a custom GATT profile over the HCI interface on my local side (not over the air).  The values updated over HCI from my host processor would eventually be seen over the LE connection by the remote side.

For the temporary solution, I'm going to try adding the case for HCI_EXT_PROFILE_SUBGRP in processExtMsg() from hci_ext_app.c, as it appears this subgroup is not being used for anything yet.

It would be nice to see an example on what TI has in mind for this subgroup, or at least some insight on the design philosophy.  Documentation is very light for this subgroup.

Any help is appreciated!

Thanks,
Chris Norris

    Hello,

    I think you are on correct track.  The only documentation for this is in hci_ext_app.h.  Maybe this allows hci msgs to a profile, but usually profile is higher at applications level. Good questions though, I'll mention it and see if anyone plans on using this, but looks like the handler would have to be developed. Sorry, not much help on this one.

    BR,
