Problem with Connecting Swift Matter Smart-Light Example to Network

[yaJannik]

Hi there,

Description

I am currently testing the Swift Matter smart-light example. The build process completed successfully, but I am encountering issues during execution. The device is recognized as a 'Matter Accessory' and I am able to enter the code. However, after this step, the device is unable to connect to the network.

System Information

Swift Version

• Swift Version: Apple Swift version 6.0-dev
• Target: x86_64-apple-macosx14.0

Software Installed

• Matter (v1.2), IDF (v5.2.2-169-g8e82062d41), etc. installed correctly

Environment Setup

• export.sh from IDF and Matter executed successfully
• TOOLCHAIN points to the correct version
• Running idf.py set-target esp32c6 works fine and confirms the Swift compiler identification as Apple 6.0

Request

Any guidance or suggestions to resolve this build issue would be greatly appreciated.

EDIT: Currently I don't have access to a JTAG Debugger. I'll ask some coworker if they can help me out.

Best regards,

I'm having the same issue.

The WWDC video "Go small with Embedded Swift" mentions that the device needs to be connected to WiFi:

The device will then join my WiFi and the HomeKit network, and it can be controlled from the Home app on any of the Apple devices.

Should connecting to WiFi happen when adding the accessory to HomeKit in the Home app (the iOS device provides the SSID and password)? Or is there some step missing to connect the ESP32 to WiFi before adding to HomeKit?

[PaulSolt]

It should get provisioned through the Home app when you set it up.

I was able to fix it by erasing everything and starting over with HomeKit.

You can reset your device using this command.

idf.py erase-flash

Then retry and build and run

idf.py build flash monitor

I connected with wifi normally

1. when you do idf.py set-target targetname all configs are drop and need to fix again
2. for wifi connect after set-target procedure I change CONFIG_DEFAULT_WIFI_SSID in three files:

sdkconfig
sdkconfig.h
sdkconfig.json

and build project

Or more easy way:

create file sdkconfig.defaults.esp32c3 where esp32c3 (your target name)
and append CONFIG_DEFAULT_WIFI_SSID and save
then remove build folder and call idf.py set-target esp32c3 again :)
