When the driver is loaded, it will request a connection to the remote device and release the connection request when destroyed. --- profiles/battery/battery.c | 90 ++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 90 insertions(+) diff --git a/profiles/battery/battery.c b/profiles/battery/battery.c index 7702e39..5e52275 100644 --- a/profiles/battery/battery.c +++ b/profiles/battery/battery.c @@ -30,17 +30,28 @@ #include "adapter.h" #include "device.h" +#include "gattrib.h" +#include "attio.h" #include "att.h" #include "gattrib.h" #include "gatt.h" #include "battery.h" +#include "log.h" struct battery { struct btd_device *dev; /* Device reference */ + GAttrib *attrib; /* GATT connection */ + guint attioid; /* Att watcher id */ + struct att_range *svc_range; /* Battery range */ + GSList *chars; /* Characteristics */ }; static GSList *servers; +struct characteristic { + struct gatt_char attr; /* Characteristic */ + struct battery *batt; /* Parent Battery Service */ +}; static gint cmp_device(gconstpointer a, gconstpointer b) { const struct battery *batt = a; @@ -56,20 +67,99 @@ static void battery_free(gpointer user_data) { struct battery *batt = user_data; + if (batt->chars != NULL) + g_slist_free_full(batt->chars, g_free); + + if (batt->attioid > 0) + btd_device_remove_attio_callback(batt->dev, batt->attioid); + + if (batt->attrib != NULL) + g_attrib_unref(batt->attrib); + btd_device_unref(batt->dev); g_free(batt); } +static void configure_battery_cb(GSList *characteristics, guint8 status, + gpointer user_data) +{ + struct battery *batt = user_data; + GSList *l; + + if (status != 0) { + error("Discover Battery characteristics: %s", + att_ecode2str(status)); + return; + } + + for (l = characteristics; l; l = l->next) { + struct gatt_char *c = l->data; + struct characteristic *ch; + + ch = g_new0(struct characteristic, 1); + ch->attr.handle = c->handle; + ch->attr.properties = c->properties; + ch->attr.value_handle = c->value_handle; + memcpy(ch->attr.uuid, c->uuid, MAX_LEN_UUID_STR + 1); + ch->batt = batt; + + batt->chars = g_slist_append(batt->chars, ch); + } +} + +static void attio_connected_cb(GAttrib *attrib, gpointer user_data) +{ + struct battery *batt = user_data; + + batt->attrib = g_attrib_ref(attrib); + + if (batt->chars == NULL) { + gatt_discover_char(batt->attrib, batt->svc_range->start, + batt->svc_range->end, NULL, + configure_battery_cb, batt); + } +} + +static void attio_disconnected_cb(gpointer user_data) +{ + struct battery *batt = user_data; + + g_attrib_unref(batt->attrib); + batt->attrib = NULL; +} + +static gint primary_uuid_cmp(gconstpointer a, gconstpointer b) +{ + const struct gatt_primary *prim = a; + const char *uuid = b; + + return g_strcmp0(prim->uuid, uuid); +} int battery_register(struct btd_device *device) { struct battery *batt; + struct gatt_primary *prim; + GSList *primaries, *l; + + primaries = btd_device_get_primaries(device); + + l = g_slist_find_custom(primaries, BATTERY_SERVICE_UUID, + primary_uuid_cmp); + prim = l->data; batt = g_new0(struct battery, 1); batt->dev = btd_device_ref(device); + batt->svc_range = g_new0(struct att_range, 1); + batt->svc_range->start = prim->range.start; + batt->svc_range->end = prim->range.end; + servers = g_slist_prepend(servers, batt); + batt->attioid = btd_device_add_attio_callback(device, + attio_connected_cb, attio_disconnected_cb, + batt); return 0; } -- 1.7.9.5
