2.3.9 ESP Local Control
Overview
ESP Local Control (esp_local_ctrl) component in ESP-IDF provides capability to control an ESP device over Wi-Fi
+ HTTPS or BLE. It provides access to application defined properties that are available for reading / writing via a
set of configurable handlers.
Initialization of the esp_local_ctrl service over BLE transport is performed as follows:
esp_local_ctrl_config_t config = {
.transport = ESP_LOCAL_CTRL_TRANSPORT_BLE,
.transport_config = {
.ble = & (protocomm_ble_config_t) {
.device_name = SERVICE_NAME,
.service_uuid = {
/* LSB <---------------------------------------
* ---------------------------------------> MSB */
0x21, 0xd5, 0x3b, 0x8d, 0xbd, 0x75, 0x68, 0x8a,
0xb4, 0x42, 0xeb, 0x31, 0x4a, 0x1e, 0x98, 0x3d
}
}
},
.proto_sec = {
.version = PROTOCOM_SEC0,
.custom_handle = NULL,
.pop = NULL,
},
.handlers = {
/* User defined handler functions */
.get_prop_values = get_property_values,
.set_prop_values = set_property_values,
.usr_ctx = NULL,
.usr_ctx_free_fn = NULL
},
/* Maximum number of properties that may be set */
.max_properties = 10
};
/* Start esp_local_ctrl service */
ESP_ERROR_CHECK(esp_local_ctrl_start(&config));
Similarly for HTTPS transport:
/* Set the configuration */
httpd_ssl_config_t https_conf = HTTPD_SSL_CONFIG_DEFAULT();
/* Load server certificate */
extern const unsigned char cacert_pem_start[] asm("_binary_cacert_pem_
,→start");
extern const unsigned char cacert_pem_end[] asm("_binary_cacert_pem_end
,→");
https_conf.cacert_pem = cacert_pem_start;
https_conf.cacert_len = cacert_pem_end - cacert_pem_start;
