ESP-IDF Gatt Client Multi Connection Demo
This is the demo of APIs to create a GATT multi-connection client. It can be used to connect to three GATT servers at the same time.
To test this demo, please run gatt_server_demo to create three GATT server devices, namely ESP_GATTS_DEMO_a, ESP_GATTS_DEMO_b and ESP_GATTS_DEMO_c, Gatt_client_multi_connection_demo will connect to these three gatt server demos, and then exchange data.
The code can be modified to connect to more devices (up to 4 devices by default). If you need to connect to more devices (more than 4 devices), you need to change BT/BLE MAX ACL CONNECTIONS in menuconfig.
Please check the tutorial for more information about this example.
