SmartConfig example does not save it's credentials (IDFGH-1200)

exocode commented 5 years ago

Environment

Development Kit: [Heltec EPS32]
Module or chip used: [ESP32-ESP32]
IDF version (run git describe --tags to find it): // v3.2-dev-1148-g96cd3b75c
Build System: [Platformio 1.8 (ESP-IDF ]
Compiler version (run xtensa-esp32-elf-gcc --version to find it): // xtensa-esp32-elf-gcc (crosstool-NG crosstool-ng-1.22.0-80-g6c4433a) 5.2.0
Operating System: [macOS]
Power Supply: [USB]

Problem Description

When use the SmartConfig example, assign a network and reboot the ESP32, the credentials are not saved.

Expected Behavior

When I reboot ESP32 the saved credentials should be recalled and ESP32 should connect automatically to latest working Wifi

Actual Behavior

When I reboot a before successfully connected ESP32, it keeps hanging in SC_STATUS_FIND_CHANNEL (waiting for new credentials)

Steps to reproduce

copy paste the smartConfig example: https://github.com/espressif/esp-idf/tree/master/examples/wifi/smart_config
build and run the example
Download and install one of Espressif's Mobile phone apps and connect to a Wifi Network
Connect the ESP32 to the Wifi Network via the mobile app
Wait till it's connected
press the reboot button on your board
see that SC_STATUS_FIND_CHANNEL is active (which shouldn't)

Code to reproduce this issue

Use your example code https://github.com/espressif/esp-idf/blob/master/examples/wifi/smart_config/main/smartconfig_main.c

hi, @exocode The example will start smartconfig after reboot. log is : I (300) wifi: mode : sta (cc:50:e3:81:be:78) I (350) smartconfig: SC version: V2.8.0 I (5170) wifi: ic_enable_sniffer SC_STATUS_FIND_CHANNEL

In this state, it will not connect to the wireless network connection, but wait for the ESP_touch distribution network.

If you need it to save it's credentials,ou can modify the code to start smatrconfig with a command.

exocode commented 5 years ago

Ok I understand, thank you. I suggest for consistency extending the example with the permanent store of the credentials as it is in the WPS config example. Most use cases are using permanent storage.

Thank you for your suggestion.

@exocode Thanks for reporting. Feel free to reopen if you still have the issue. Thanks.

Was this implemented or not ? The example still does not save the wifi creds.
