ESP-IDF GATT SERVER demo
========================
This is the demo for user to use ESP_APIs to create a GATT Server.
Options choose step:
1. make menuconfig.
2. enter menuconfig "Component config".
3. enter menuconfig "Example 'GATT SERVER' Config".
4. choose your options.
UPDATE NOTE
===========
2017-01-19:
1. Use New APIs to set raw advertising data and raw scan response data.
2. Could use macro CONFIG_SET_RAW_ADV_DATA (should use menuconfig) to config use raw advertising/scan_response
or use structure do automatically config. The macro CONFIG_SET_RAW_ADV will effect both advertising data
and scan_response data.
This is the demo for user to use ESP_APIs to create a GATT Server.The demo can send adv data,
be connected by client. Run the gatt_client demo, the client demo will automatically connect
to the gatt_server demo. The client demo will enable gatt_server's notify after connection.
Then the two devices will exchange data.
