This patch adds a argument when creating the mcap instance to set authorize method. The reason why we don't use btd_request_authorization directly like all other profiles is because tools/mcaptest includes the profile/health/mcap.h. If we add dependency to adapter.h in mcap.h, it will make mcaptest depend on adapter and be not able to build independently. --- (no changes since v1) profiles/health/hdp.c | 1 + profiles/health/mcap.c | 39 +++++++++++++++++++++++++++++++++++++-- profiles/health/mcap.h | 7 +++++++ tools/mcaptest.c | 2 +- 4 files changed, 46 insertions(+), 3 deletions(-) diff --git a/profiles/health/hdp.c b/profiles/health/hdp.c index 6bc41946f..efa8955ef 100644 --- a/profiles/health/hdp.c +++ b/profiles/health/hdp.c @@ -1347,6 +1347,7 @@ static gboolean update_adapter(struct hdp_adapter *hdp_adapter) mcl_connected, mcl_reconnected, mcl_disconnected, mcl_uncached, NULL, /* CSP is not used by now */ + btd_request_authorization, hdp_adapter, &err);
