From 7c3ca2a6b940d36c553fabe38066fabc66530dc9 Mon Sep 17 00:00:00 2001 From: Curtis Maves Date: Mon, 12 Apr 2021 16:34:26 -0400 Subject: [PATCH] gatt: Either notify or indicate, do not do both AcquireNotify and StartNotify starts notifications and/or indications by whether the characteristic supports them. Before this patch, if both were supported, Bluez would try to start both simultaneously. This patch changes this behavior so if both are supported, only notifications are started. Test cases have also be updated accordingly. --- src/shared/gatt-client.c | 10 +++++----- unit/test-gatt.c | 43 +++++++++++++++++++++++++++------------- 2 files changed, 34 insertions(+), 19 deletions(-) diff --git a/src/shared/gatt-client.c b/src/shared/gatt-client.c index 4e10f244d..9511ea8ca 100644 --- a/src/shared/gatt-client.c +++ b/src/shared/gatt-client.c @@ -1585,20 +1585,20 @@ static bool notify_data_write_ccc(struct notify_data *notify_data, bool enable, { uint8_t pdu[4]; unsigned int att_id; + uint16_t properties = notify_data->chrc->properties; assert(notify_data->chrc->ccc_handle); memset(pdu, 0, sizeof(pdu)); put_le16(notify_data->chrc->ccc_handle, pdu); if (enable) { - /* Try to enable notifications and/or indications based on + /* Try to enable notifications or indications based on * whatever the characteristic supports. */ - if (notify_data->chrc->properties & BT_GATT_CHRC_PROP_NOTIFY) + if (properties & BT_GATT_CHRC_PROP_NOTIFY) pdu[2] = 0x01; - - if (notify_data->chrc->properties & BT_GATT_CHRC_PROP_INDICATE) - pdu[2] |= 0x02; + else if (properties & BT_GATT_CHRC_PROP_INDICATE) + pdu[2] = 0x02; if (!pdu[2]) return false; diff --git a/unit/test-gatt.c b/unit/test-gatt.c index 4aa87d09c..6a47268e6 100644 --- a/unit/test-gatt.c +++ b/unit/test-gatt.c @@ -241,8 +241,8 @@ struct context { #define CHARACTERISTIC_DISC_SMALL_DB \ raw_pdu(0x08, 0x01, 0x00, 0xff, 0xff, 0x03, 0x28), \ raw_pdu(0x09, 0x07, 0x02, 0x00, 0xb2, 0x03, 0x00, 0x29, \ - 0x2a), \ - raw_pdu(0x08, 0x03, 0x00, 0xff, 0xff, 0x03, 0x28), \ + 0x2a, 0x07, 0x00, 0x22, 0x08, 0x00, 0x28, 0x2a),\ + raw_pdu(0x08, 0x08, 0x00, 0xff, 0xff, 0x03, 0x28), \ raw_pdu(0x09, 0x07, 0x12, 0xf0, 0x02, 0x13, 0xf0, 0x00, \ 0x2a), \ raw_pdu(0x08, 0x13, 0xf0, 0xff, 0xff, 0x03, 0x28), \ @@ -256,11 +256,17 @@ struct context { raw_pdu(0x01, 0x08, 0x18, 0xf0, 0x0a) #define DESCRIPTOR_DISC_SMALL_DB \ - raw_pdu(0x04, 0x04, 0x00, 0x10, 0x00), \ + raw_pdu(0x04, 0x04, 0x00, 0x06, 0x00), \ raw_pdu(0x05, 0x01, 0x04, 0x00, 0x02, 0x29, 0x05, 0x00, \ 0x01, 0x29), \ - raw_pdu(0x04, 0x06, 0x00, 0x10, 0x00), \ - raw_pdu(0x01, 0x04, 0x06, 0x00, 0x0a), \ + raw_pdu(0x04, 0x06, 0x00, 0x06, 0x00), \ + raw_pdu(0x05, 0x01, 0x06, 0x00, 0x00, 0x29), \ + raw_pdu(0x0a, 0x06, 0x00), \ + raw_pdu(0x0b, 0x01, 0x00), \ + raw_pdu(0x04, 0x09, 0x00, 0x10, 0x00), \ + raw_pdu(0x05, 0x01, 0x09, 0x00, 0x02, 0x29), \ + raw_pdu(0x04, 0x0a, 0x00, 0x10, 0x00), \ + raw_pdu(0x01, 0x04, 0x0a, 0x00, 0x0a), \ raw_pdu(0x04, 0x16, 0xf0, 0x16, 0xf0), \ raw_pdu(0x05, 0x01, 0x16, 0xf0, 0x00, 0x29), \ raw_pdu(0x0a, 0x16, 0xf0), \ @@ -1565,6 +1571,13 @@ static struct gatt_db *make_test_spec_small_db(void) "Manufacturer Name"), DESCRIPTOR(GATT_CHARAC_EXT_PROPER_UUID, BT_ATT_PERM_READ, 0x01, 0x00), + CHARACTERISTIC_STR(GATT_CHARAC_SOFTWARE_REVISION_STRING, + BT_ATT_PERM_READ, + BT_GATT_CHRC_PROP_READ | + BT_GATT_CHRC_PROP_INDICATE, + "5.59"), + DESCRIPTOR(GATT_CLIENT_CHARAC_CFG_UUID, BT_ATT_PERM_READ + | BT_ATT_PERM_WRITE, 0x00, 0x00), PRIMARY_SERVICE(0xF010, GAP_UUID, 9), INCLUDE(0x0001), @@ -2308,7 +2321,7 @@ static void test_indication(struct context *context) } static const struct test_step test_indication_1 = { - .handle = 0x0003, + .handle = 0x0008, .func = test_indication, .value = read_data_1, .length = 0x03, @@ -2573,9 +2586,10 @@ int main(int argc, char *argv[]) raw_pdu(0x03, 0x00, 0x02), raw_pdu(0x08, 0x01, 0x00, 0x0f, 0x00, 0x03, 0x28), raw_pdu(0x09, 0x07, 0x02, 0x00, 0xb2, 0x03, 0x00, 0x29, - 0x2a), - raw_pdu(0x08, 0x03, 0x00, 0x0f, 0x00, 0x03, 0x28), - raw_pdu(0x01, 0x08, 0x03, 0x00, 0x0a)); + 0x2a, 0x07, 0x00, 0x22, 0x08, 0x00, + 0x28, 0x2a), + raw_pdu(0x08, 0x08, 0x00, 0x0f, 0x00, 0x03, 0x28), + raw_pdu(0x01, 0x08, 0x08, 0x00, 0x0a)); define_test_server("/TP/GAD/SR/BV-04-C/large-1", test_server, ts_large_db_1, NULL, @@ -2626,9 +2640,10 @@ int main(int argc, char *argv[]) raw_pdu(0x03, 0x00, 0x02), raw_pdu(0x08, 0x01, 0x00, 0x0f, 0x00, 0x03, 0x28), raw_pdu(0x09, 0x07, 0x02, 0x00, 0xb2, 0x03, 0x00, 0x29, - 0x2a), - raw_pdu(0x08, 0x03, 0x00, 0x0f, 0x00, 0x03, 0x28), - raw_pdu(0x01, 0x08, 0x03, 0x00, 0x0a)); + 0x2a, 0x07, 0x00, 0x22, 0x08, 0x00, + 0x28, 0x2a), + raw_pdu(0x08, 0x08, 0x00, 0x0f, 0x00, 0x03, 0x28), + raw_pdu(0x01, 0x08, 0x08, 0x00, 0x0a)); define_test_server("/TP/GAD/SR/BV-05-C/large-1", test_server, ts_large_db_1, NULL, @@ -3241,7 +3256,7 @@ int main(int argc, char *argv[]) &test_notification_1, CLIENT_INIT_PDUS, SMALL_DB_DISCOVERY_PDUS, - raw_pdu(0x12, 0x04, 0x00, 0x03, 0x00), + raw_pdu(0x12, 0x04, 0x00, 0x01, 0x00), raw_pdu(0x13), raw_pdu(), raw_pdu(0x1B, 0x03, 0x00, 0x01, 0x02, 0x03)); @@ -3267,7 +3282,7 @@ int main(int argc, char *argv[]) &test_indication_1, CLIENT_INIT_PDUS, SMALL_DB_DISCOVERY_PDUS, - raw_pdu(0x12, 0x04, 0x00, 0x03, 0x00), + raw_pdu(0x12, 0x09, 0x00, 0x02, 0x00), raw_pdu(0x13), raw_pdu(), raw_pdu(0x1D, 0x03, 0x00, 0x01, 0x02, 0x03), -- 2.47.3
