# gatt_server_notif_switch
A sample program for ESP32 on esp-idf. This program send notification by push or release GPIO0 switch.
# Partner program
The following nodejs program can listen notice from this project.

menu "Example 'GATT SERVER' Config"
config SET_RAW_ADV_DATA
bool "Use raw data for advertising packets and scan response data"
help
If this config item is set, raw binary data will be used to generate advertising & scan response data.
This option uses the esp_ble_gap_config_adv_data_raw() and esp_ble_gap_config_scan_rsp_data_raw() functions.
If this config item is unset, advertising & scan response data is provided via a higher-level esp_ble_adv_data_t structure.
The lower layer will generate the BLE packets. This option has higher overhead at runtime.

# Main Makefile. This is basically the same as a component makefile.
#
# This Makefile should, at the very least, just include $(SDK_PATH)/make/component_common.mk. By default,
# this will take the sources in the src/ directory, compile them and link them into
# lib(subdirectory_name).a in the build directory. This behaviour is entirely configurable,
# please read the ESP-IDF documents if you need to do this.
