From b75f8b1b20c2b3c470b0b611125891e60c1d0de9 Mon Sep 17 00:00:00 2001 From: Anurag Kar Date: Wed, 26 Jun 2019 01:03:55 +0530 Subject: [PATCH] ESP Local Control Feature Added List of changes: * New component esp_local_ctrl added * Example added under examples/protocols/esp_local_ctrl * Documentation added under protocols/esp_local_ctrl * Demo client side app esp_local_ctrl.py added under examples/protocols/esp_local_ctrl/scripts * protocomm_ble : protocomm_ble_config_t given struct name for allowing forward declaration * esp_prov/transport_softap renamed to transport_http * transport_http module supports verification of server certificate * transport_http module performs name resolution before connection --- .flake8 | 1 + components/esp_local_ctrl/CMakeLists.txt | 23 +

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. + + .. highlight:: c + + :: + + /* Create a timestamp property */ + esp_local_ctrl_prop_t timestamp = { + .name = "timestamp", + .type = TYPE_TIMESTAMP, + .size = sizeof(int32_t), + .flags = READONLY, + .ctx = func_get_time, + .ctx_free_fn = NULL + }; + + /* Now register the property */ + esp_local_ctrl_add_property(×tamp); + + +Also notice that there is a ctx field, which is set to point to some custom `func_get_time()`. This can be used inside the property get / set handlers to retrieve timestamp. + +Here is an example of `get_prop_values()` handler, which is used for retrieving the timestamp. + + .. highlight:: c + + :: + + static esp_err_t get_property_values(size_t props_count, + const esp_local_ctrl_prop_t *props, + esp_local_ctrl_prop_val_t *prop_values, + void *usr_ctx) + { + for (uint32_t i = 0; i < props_count; i++) { + ESP_LOGI(TAG, "Reading %s", props[i].name); + if (props[i].type == TYPE_TIMESTAMP) { + /* Obtain the timer function from ctx */ + int32_t (*func_get_time)(void) = props[i].ctx; + + /* Use static variable for saving the value. + * This is essential because the value has to be + * valid even after this function returns. + * Alternative is to use dynamic allocation + * and set the free_fn field */ + static int32_t ts = func_get_time(); + prop_values[i].data = &ts; + } + } + return ESP_OK; + } + + +Here is an example of `set_prop_values()` handler.

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) + - URI (HTTPS Server + mDNS) + - Description + * - esp_local_ctrl/version + - https://.local/esp_local_ctrl/version + - Endpoint used for retrieving version string + * - esp_local_ctrl/control + - https://.local/esp_local_ctrl/control + - Endpoint used for sending / receiving control messages + + +API Reference +------------- + +.. include:: /_build/inc/esp_local_ctrl.inc diff --git a/docs/en/api-reference/protocols/index.rst b/docs/en/api-reference/protocols/index.rst index 97386abe4c..c35c954f35 100644 --- a/docs/en/api-reference/protocols/index.rst +++ b/docs/en/api-reference/protocols/index.rst @@ -14,6 +14,7 @@ Application Protocols ASIO ESP-MQTT Modbus + Local Control Code examples for this API section are provided in the :example:`protocols` directory of ESP-IDF examples. diff --git a/docs/zh_CN/api-reference/protocols/esp_local_ctrl.rst b/docs/zh_CN/api-reference/protocols/esp_local_ctrl.rst new file mode 100644 index 0000000000..587542d5d8 --- /dev/null +++ b/docs/zh_CN/api-reference/protocols/esp_local_ctrl.rst @@ -0,0 +1 @@ +.. include:: ../../../en/api-reference/protocols/esp_local_ctrl.rst diff --git a/docs/zh_CN/api-reference/protocols/index.rst b/docs/zh_CN/api-reference/protocols/index.rst index 9d893c29b6..d385082b3b 100644 --- a/docs/zh_CN/api-reference/protocols/index.rst +++ b/docs/zh_CN/api-reference/protocols/index.rst @@ -14,6 +14,7 @@ ASIO ESP-MQTT Modbus slave + Local Control 此 API 部分的示例代码在 ESP-IDF 示例工程的 :example:`protocols` 目录下提供。 diff --git a/examples/protocols/esp_local_ctrl/CMakeLists.txt b/examples/protocols/esp_local_ctrl/CMakeLists.txt new file mode 100644 index 0000000000..2ee3492ecb --- /dev/null +++ b/examples/protocols/esp_local_ctrl/CMakeLists.txt @@ -0,0 +1,10 @@ +# The following lines of boilerplate have to be in your project's CMakeLists +# in this exact order for cmake to work correctly +cmake_minimum_required(VERSION 3.5) + +# (Not part of the boilerplate) +# This example uses an extra component for common functions such as Wi-Fi and Ethernet connection. +set(EXTRA_COMPONENT_DIRS $ENV{IDF_PATH}/examples/common_components/protocol_examples_common) + +include($ENV{IDF_PATH}/tools/cmake/project.cmake) +project(esp_local_ctrl) diff --git a/examples/protocols/esp_local_ctrl/Makefile b/examples/protocols/esp_local_ctrl/Makefile new file mode 100644 index 0000000000..e3e0a7ac6d --- /dev/null +++ b/examples/protocols/esp_local_ctrl/Makefile @@ -0,0 +1,9 @@ +# +# This is a project Makefile.
