[PATCH 0/6] Add included services discovery

[PATCH 0/6] Add included services discovery

[Marcin Kraglak]

This patch set implements searching of included services.
It is based on previous patches to gatt-helper.
Additionally flag primary is introduced in bt_gatt_service_t
to know type of service. It will be needed in Android
gatt part too.
Included service discovery start right after primary discovery
finish. If include service declaration was found, and it was
not found in primary discovery, it's just simply added as
secondary service.
There is TODO part: we should check if included services
have other includes too, because nested includes are
allowed SPEC. We can consider recursive calls.

Comments are welcome
Marcin

Re: [PATCH 4/6] shared/gatt: Add Secondary services to service_list

[Arman Uguray]

Hi Marcin,


> If included service was found and doesn't exist on service list,
> create Secondary Service and insert it.

I guess this is somewhat of an optimization but wouldn't it be more
robust to actually perform secondary service discovery? I mean after
discovering all the primary services, should we also send a bunch of
Read By Group Type requests with the secondary service UUID? You could
modify bt_gatt_discover_primary_services so that it accepts a boolean
parameter (perhaps rename it to bt_gatt_discover_services) and uses
the correct UUID based on that. Do you think that would be a better
approach?

I would use "iter" instead of "i" to keep it consistent with the rest
of the code (here and elsewhere).

If we discover secondary first, then we won't have to recursive search
for include services.
I didn't implement this just because it wasn't listed in gatt feature
requirements in SPEC.
But I think that is good approach. I'll send patches
