The ADV name is `ESP_GATTS_DEMO`, then waits to be connected. At the same time, a gatt client is created, the ADV name is `ESP_GATTS_DEMO`, the device is connected, and the data is exchanged. If the device is not found within 120 seconds, the example will stop scanning. + +ESP-IDF also allows users to create a GATT service via an attribute table, rather than add attributes one by one. And it is recommended for users to use. For more information about this method, please refer to [gatt_server_service_table_demo](../gatt_server_service_table). + +To test this example, you can run the [gatt_client_demo](../gatt_client), which can scan for and connect to this example automatically, and run [gatt_server_demo](../gatt_server), Waiting to be connected. They will start exchanging data once the GATT client has enabled the notification function of the GATT server. + +Please check the [tutorial](tutorial/Gatt_Server_Example_Walkthrough.md) for more information about the gatts part of this example. +Please check the [tutorial](tutorial/Gatt_Client_Example_Walkthrough.md) for more information about the gattc part of this example. + diff --git a/examples/bluetooth/gattc_gatts_coex/main/CMakeLists.txt b/examples/bluetooth/gattc_gatts_coex/main/CMakeLists.txt new file mode 100644 index 0000000000..a3c8592c8d --- /dev/null +++ b/examples/bluetooth/gattc_gatts_coex/main/CMakeLists.txt @@ -0,0 +1,4 @@ +set(COMPONENT_SRCS "gattc_gatts_coex.c") +set(COMPONENT_ADD_INCLUDEDIRS ".") + +register_component() diff --git a/examples/bluetooth/gattc_gatts_coex/main/component.mk b/examples/bluetooth/gattc_gatts_coex/main/component.mk new file mode 100644 index 0000000000..a98f634eae --- /dev/null +++ b/examples/bluetooth/gattc_gatts_coex/main/component.mk @@ -0,0 +1,4 @@ +# +# "main" pseudo-component makefile. +# +# (Uses default behaviour of compiling all source files in directory, adding 'include' to include path.) diff --git a/examples/bluetooth/gattc_gatts_coex/main/gattc_gatts_coex.c b/examples/bluetooth/gattc_gatts_coex/main/gattc_gatts_coex.c new file mode 100644 index 0000000000..3e4989372c --- /dev/null +++ b/examples/bluetooth/gattc_gatts_coex/main/gattc_gatts_coex.c @@ -0,0 +1,1028 @@ +/* + This example code is in the Public Domain (or CC0 licensed, at your option.) + + Unless required by applicable law or agreed to in writing, this + software is distributed on an "AS IS" BASIS, WITHOUT WARRANTIES OR + CONDITIONS OF ANY KIND, either express or implied. +*/ + +#include +#include +#include +#include +#include "nvs.h" +#include "nvs_flash.h" +#include "esp_log.h" +#include "freertos/FreeRTOS.h" +#include "freertos/event_groups.h" +#include "esp_bt.h" +#include "esp_gap_ble_api.h" +#include "esp_gattc_api.h" +#include "esp_gatt_defs.h" +#include "esp_bt_main.h" +#include "esp_gatt_common_api.h" +#include "esp_gatts_api.h" +#include "esp_bt_defs.h" +#include "esp_system.h" +#include "sdkconfig.h" + + +#define GATTS_SERVICE_UUID_TEST_A 0x00FF +#define GATTS_CHAR_UUID_TEST_A 0xFF01 +#define GATTS_NUM_HANDLE_TEST_A 4 + +#define GATTS_SERVICE_UUID_TEST_B 0x00EE +#define GATTS_CHAR_UUID_TEST_B 0xEE01 +#define GATTS_NUM_HANDLE_TEST_B 4 + +#define GATTS_DEMO_CHAR_VAL_LEN_MAX 0x40 +#define PREPARE_BUF_MAX_SIZE 1024 + +#define adv_config_flag (1 << 0) +#define scan_rsp_config_flag (1 << 1) + +#define GATTS_PROFILE_NUM 2 +#define GATTS_PROFILE_A_APP_ID 0 +#define GATTS_PROFILE_B_APP_ID 1 +#define GATTC_PROFILE_NUM 1 +#define GATTC_PROFILE_C_APP_ID 0 +// gattc +#define REMOTE_SERVICE_UUID 0x00FF +#define REMOTE_NOTIFY_CHAR_UUID 0xFF01 +#define INVALID_HANDLE 0 +#define GATTS_ADV_NAME "ESP_GATTS_DEMO" +#define COEX_TAG "GATTC_GATTS_COEX" +#define NOTIFY_ENABLE 0x0001 +#define INDICATE_ENABLE 0x0002 +#define NOTIFY_INDICATE_DISABLE 0x0000 + +static const char remote_device_name[] = "ESP_GATTS_DEMO";
