lwip was added to common requirements list to provide "sys/socket.h" header to all components without additional requirements specified. However, lwip pulls in a lot of dependencies on other components. This commit removes lwip from common requirements to reduce the number of components in G1-only apps. To compensate for this removal, the following changes are made: - newlib (which is a common requirement) has a public dependency on lwip if lwip is present in the build. This ensures that sys/socket.h is available as long as lwip component is included into the build. - lwip is now a public requirement of esp-tls since esp_tls.h includes sys/socket.h header. - lwip is now a public requirement o esp_http_client because sys/socket.h is included from esp_http_client.h - lwip is now a private requirement of esp_wifi for "smartconfig_ack" - lwip is now a private requirement of mqtt for socket functions - lwip is now a public requirement of tcp_transport because esp_transport_tcp.h includes sys/socket.h header. - mbedtls checks if lwip component is present in the build. If yes, net_sockets.c is added to the build, along with the dependency on lwip. Previously lwip was a public requirement of mbedtls unconditionally. system/g1_components test app is updated to reflect the changes Default public dependencies of a component before and after this change, except common requirements: - esp_timer (public dependency of freertos) - bootloader_support (public dependency of esp_hw_support) - vfs (public dependency of lwip) - esp_wifi (public dependency of lwip) - esp_event (public dependency of esp_wifi) - esp_netif (public dependency of esp_event) - esp_eth (public dependency of esp_netif) - esp_phy (public dependency of esp_wifi) After: - esp_timer (public dependency of freertos) - bootloader_support (public dependency of esp_hw_support) Altogether, the following components have been always added as public requirements to all other components, and are not added now ([breaking-change]): - lwip - vfs - esp_wifi - esp_event - esp_netif - esp_eth - esp_phy Application components now need to explicitly declare dependencies on these components.
ESP32 MQTT Library
Features
- Based on: https://github.com/tuanpmt/esp_mqtt
- Support MQTT over TCP, SSL with mbedtls, MQTT over Websocket, MQTT over Websocket Secure
- Easy to setup with URI
- Multiple instances (Multiple clients in one application)
- Support subscribing, publishing, authentication, will messages, keep alive pings and all 3 QoS levels (it should be a fully functional client).
