The current approach uses the active scanning with default windows and intervals defined by the core spec without any filtering. --- src/mgmt.c | 34 ++++++++++++++++++++++++++++++++++ src/mgmt.h | 1 + 2 files changed, 35 insertions(+) diff --git a/src/mgmt.c b/src/mgmt.c index 651c940..662d70b 100644 --- a/src/mgmt.c +++ b/src/mgmt.c @@ -2005,6 +2005,40 @@ int mgmt_start_discovery(int index) return 0; } +int mgmt_start_scanning(int index) +{ + char buf[MGMT_HDR_SIZE + sizeof(struct mgmt_cp_start_discovery)]; + struct mgmt_hdr *hdr = (void *) buf; + struct mgmt_cp_start_discovery *cp = (void *) &buf[sizeof(*hdr)]; + struct controller_info *info = &controllers[index]; + + DBG("index %d", index); + + if (!mgmt_low_energy(info->current_settings)) { + error("scanning failed: Low Energy not enabled/supported"); + return -ENOTSUP; + } + + info->discov_type = 0; + hci_set_bit(BDADDR_LE_PUBLIC, &info->discov_type); + hci_set_bit(BDADDR_LE_RANDOM, &info->discov_type); + + memset(buf, 0, sizeof(buf)); + hdr->opcode = htobs(MGMT_OP_START_DISCOVERY); + hdr->len = htobs(sizeof(*cp)); + hdr->index = htobs(index); + + cp->type = info->discov_type; + + if (write(mgmt_sock, buf, sizeof(buf)) < 0) { + int err = -errno; + error("failed to write to MGMT socket: %s", strerror(-err)); + return err; + } + + return 0; +} + int mgmt_stop_discovery(int index) { char buf[MGMT_HDR_SIZE + sizeof(struct mgmt_cp_start_discovery)]; diff --git a/src/mgmt.h b/src/mgmt.h index 95245d2..eb7434a 100644 --- a/src/mgmt.h +++ b/src/mgmt.h @@ -33,6 +33,7 @@ int mgmt_set_dev_class(int index, uint8_t major, uint8_t minor); int mgmt_set_fast_connectable(int index, gboolean enable); int mgmt_start_discovery(int index); +int mgmt_start_scanning(int index); int mgmt_stop_discovery(int index); int mgmt_read_clock(int index, bdaddr_t *bdaddr, int which, int timeout, -- 1.7.11.4
