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) android/health.c | 2 +- profiles/health/hdp.c | 1 + profiles/health/mcap.c | 39 +++++++++++++++++++++++++++++++++++++-- profiles/health/mcap.h | 7 +++++++ tools/mcaptest.c | 2 +- 5 files changed, 47 insertions(+), 4 deletions(-) diff --git a/android/health.c b/android/health.c index 9a29964b1be2..de50db98e988 100644 --- a/android/health.c +++ b/android/health.c @@ -2008,7 +2008,7 @@ bool bt_health_register(struct ipc *ipc, const bdaddr_t *addr, uint8_t mode) mcl_connected, mcl_reconnected, mcl_disconnected, mcl_uncached, NULL, /* CSP is not used right now */ - NULL, &err);
