David Cermak 84039dc77d esp_modem: Fixed race condition on exiting PPP mode 
esp_modem_stop_ppp() stops both ppp netif and switches the modem back to
command mode. IF these two actions are not synchronised, we might
experience issues of
* active PPP session trying to send/receive uart-data
* command mode already active before modem switched to it
both resulting in crashes.
Fixed by introducing the transition mode and running these actions in sequence
* set esp-modem to transition mode
* enter command mode, wait for the reply or re-sync
* close the PPP netif
* wait until the netif closes
Other fixes include ignoring certain events if modem component not ready
or not in appropriate mode:
* ignoring all UART events comming from DTE with no DCE attached
* ignore pattern detection in PPP mode

README.md

Examples

This directory contains a range of example ESP-IDF projects. These are intended to demonstrate parts of ESP-IDF functionality, and to provide code that you can copy and adapt into your own projects.

Example Layout

The examples are grouped into subdirectories by category. Each category directory contains one or more example projects:

  • bluetooth/bluedroid contains Classic BT, BLE and coex examples using default Bluedroid host stack.
  • bluetooth/nimble contains BLE examples using NimBLE host stack.
  • bluetooth/esp_ble_mesh contains ESP BLE Mesh examples.
  • bluetooth/hci contains HCI transport (VHCI and HCI UART) examples
  • ethernet contains Ethernet examples.
  • get-started contains some very simple examples with minimal functionality.
  • mesh contains Wi-Fi Mesh examples.
  • peripherals contains examples showing driver functionality for the various onboard ESP32 peripherals.
  • protocols contains examples showing network protocol interactions.
  • storage contains examples showing data storage methods using SPI flash or external storage like the SD/MMC interface.
  • system contains examples which demonstrate some internal chip features, or debugging & development tools.
  • wifi contains examples of advanced Wi-Fi features. (For network protocol examples, see protocols instead.)
  • build_system contains examples of build system features

Using Examples

Building an example is the same as building any other project:

  • Follow the Getting Started instructions which include building the "Hello World" example.
  • Change into the directory of the new example you'd like to build.
  • Run idf.py menuconfig to open the project configuration menu. Most examples have a project-specific "Example Configuration" section here (for example, to set the WiFi SSID & password to use).
  • idf.py build to build the example.
  • Follow the printed instructions to flash, or run idf.py -p PORT flash.

Copying Examples

Each example is a standalone project. The examples do not have to be inside the esp-idf directory. You can copy an example directory to anywhere on your computer in order to make a copy that you can modify and work with.

The IDF_PATH environment variable is the only thing that connects the example to the rest of ESP-IDF.

If you're looking for a more bare-bones project to start from, try esp-idf-template.

Contributing Examples

If you have a new example you think we'd like, please consider sending it to us as a Pull Request.

In the ESP-IDF documentation, you can find a "Creating Examples" page which lays out the steps to creating a top quality example.
