# Protobuf files for defining ESP Local Control message structures
The proto files under this directory are used by esp_local_ctrl for defining protobuf messages which are sent and received over protocomm transport layer. These proto files cannot be used directly and have to be compiled into C and Python files. The generated C files are used by esp_local_ctrl itself to create, delete and manipulate transaction packets. The generated Python files can be used by python based applications for implementing client side interface to esp_local_ctrl service running on a device.
Note : These proto files are not automatically compiled during the build process.
# Compilation
Compilation requires protoc (Protobuf Compiler) and protoc-c (Protobuf C Compiler) installed. Since the generated files are to remain the same, as long as the proto files are not modified, therefore the generated files are already available under `components/esp_local_ctrl/proto-c` and `components/esp_local_ctrl/python` directories, and thus running `cmake` / `make` (and installing the Protobuf compilers) is optional.
If using `cmake` follow the below steps. If using `make`, jump to Step 2 directly.
## Step 1 (Only for cmake)
When using cmake, first create a build directory and call cmake from inside:
```
mkdir build
cd build
cmake ..
```
## Step 2
Simply run `make` to generate the respective C and Python files. The newly created files will overwrite those under `components/esp_local_ctrl/proto-c` and `components/esp_local_ctrl/python`

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:
.. highlight:: c
::
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
}
}
},
.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:
.. highlight:: c
::
/* 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;
/* Load server private key */
extern const unsigned char prvtkey_pem_start[] asm("_binary_prvtkey_pem_start");
extern const unsigned char prvtkey_pem_end[] asm("_binary_prvtkey_pem_end");
https_conf.prvtkey_pem = prvtkey_pem_start;
https_conf.prvtkey_len = prvtkey_pem_end - prvtkey_pem_start;
esp_local_ctrl_config_t config = {
.transport = ESP_LOCAL_CTRL_TRANSPORT_HTTPD,
.transport_config = {
.httpd = &https_conf
},
.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));
Creating a property
===================
Now that we know how to start the **esp_local_ctrl** service, let's add a property to it. Each property must have a unique `name` (string), a `type` (e.g. enum), `flags` (bit fields) and `size`.
The `size` is to be kept 0, if we want our property value to be of variable length (e.g. if its a string or bytestream). For fixed length property value data-types, like int, float, etc., setting the `size` field to the right value, helps **esp_local_ctrl** to perform internal checks on arguments received with write requests.
The interpretation of `type` and `flags` fields is totally upto the application, hence they may be used as enumerations, bitfields, or even simple integers. One way is to use `type` values to classify properties, while `flags` to specify characteristics of a property.
Here is an example property which is to function as a timestamp. It is assumed that the application defines `TYPE_TIMESTAMP` and `READONLY`, which are used for setting the `type` and `flags` fields here.

Client Side Implementation
==========================
The client side implementation will have establish a protocomm session with the device first, over the supported mode of transport, and then send and receive protobuf messages understood by the **esp_local_ctrl** service. The service will translate these messages into requests and then call the appropriate handlers (set / get). Then, the generated response for each handler is again packed into a protobuf message and transmitted back to the client.
See below the various protobuf messages understood by the **esp_local_ctrl** service:
1. `get_prop_count` : This should simply return the total number of properties supported by the service
2. `get_prop_values` : This accepts an array of indices and should return the information (name, type, flags) and values of the properties corresponding to those indices
3. `set_prop_values` : This accepts an array of indices and an array of new values, which are used for setting the values of the properties corresponding to the indices
Note that indices may or may not be the same for a property, across multiple sessions. Therefore, the client must only use the names of the properties to uniquely identify them. So, every time a new session is established, the client should first call `get_prop_count` and then `get_prop_values`, hence form an index to name mapping for all properties. Now when calling `set_prop_values` for a set of properties, it must first convert the names to indexes, using the created mapping. As emphasized earlier, the client must refresh the index to name mapping every time a new session is established with the same device.
The various protocomm endpoints provided by **esp_local_ctrl** are listed below:
.. list-table:: Endpoints provided by ESP Local Control
:widths: 10 25 50
:header-rows: 1
* - Endpoint Name (BLE + GATT Server)

# ESP Local Control using HTTPS server
This example creates a `esp_local_ctrl` service over HTTPS transport, for securely controlling the device over local network. In this case the device name is resolved through `mDNS`, which in this example is `my_esp_ctrl_device.local`.
See the `esp_local_ctrl` component documentation for details.
Before using the example, run `make menuconfig` (or `idf.py menuconfig` if using CMake build system) to configure Wi-Fi or Ethernet. See "Establishing Wi-Fi or Ethernet Connection" section in [examples/protocols/README.md](../README.md) for more details.
## Client Side Implementation
A python test script `scripts/esp_local_ctrl.py` has been provided for as a client side application for controlling the device over the same Wi-Fi network. The script relies on a pre-generated `main/certs/rootCA.pem` to verify the server certificate. The server side private key and certificate can also be found under `main/certs`, namely `prvtkey.pem` and `cacert.pem`.
After configuring the Wi-Fi, flashing and booting the device, run:
```
python scripts/esp_local_ctrl.py
```
Sample output:
```
python2 scripts/esp_local_ctrl.py

```
The script also allows to connect over BLE, and provide a custom service name. To display the list of supported parameters, run:
```
python scripts/esp_local_ctrl.py --help
```
## Certificates
You can generate a new server certificate using the OpenSSL command line tool.
For the purpose of this example, lets generate a rootCA, which we will use to sign the server certificates and which the client will use to verify the server certificate during SSL handshake. You will need to set a password for encrypting the generated `rootkey.pem`.
```
openssl req -new -x509 -subj "/CN=root" -days 3650 -sha256 -out rootCA.pem -keyout rootkey.pem
```
Now generate a certificate signing request for the server, along with its private key `prvtkey.pem`.
```
openssl req -newkey rsa:2048 -nodes -keyout prvtkey.pem -days 3650 -out server.csr -subj "/CN=my_esp_ctrl_device.local"
```
Now use the previously generated rootCA to process the server's certificate signing request, and generate a signed certificate `cacert.pem`. The password set for encrypting `rootkey.pem` earlier, has to be entered during this step.
```
openssl x509 -req -in server.csr -CA rootCA.pem -CAkey rootkey.pem -CAcreateserial -out cacert.pem -days 500 -sha256
```
Now that we have `rootCA.pem`, `cacert.pem` and `prvtkey.pem`, copy these into main/certs. Note that only the server related files (`cacert.pem` and `prvtkey.pem`) are embedded into the firmware.
Expiry time and metadata fields can be adjusted in the invocation.
Please see the `openssl` man pages (man `openssl-req`) for more details.
It is **strongly recommended** to not reuse the example certificate in your application;
it is included only for demonstration.
