System Crash with WiFi and Bluetooth (Client & Server) Enabled - Assertion Error in llc_disconnect.c 363 (IDFGH-13512)

matreshka15 commented 3 weeks ago

Answers checklist.

[X] I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
[X] I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
[X] I have searched the issue tracker for a similar issue and not found a similar issue.

IDF version.

5.1.4

Espressif SoC revision.

ESP32-S3 (QFN56) (revision v0.2)

Operating System used.

Windows

How did you build your project?

VS Code IDE

If you are using Windows, please specify command line type.

None

Development Kit.

Custom Board

Power Supply used.

Battery

What is the expected behavior?

Enable both WiFi and Bluetooth, with Bluetooth operating in both client and server modes. ESP32S3 should connect to other server devices smoothly.

What is the actual behavior?

Enable both WiFi and Bluetooth, with Bluetooth operating in both client and server modes, my system sometimes crashes when ESP32S3 trys to connect to one of the two server devices with the following error: assert llc_disconnect.c 363, param 00000004 00000009

This error leads to a system crash, and I have not been able to identify the root cause. I have tried various configurations, but the problem persists.

Steps to reproduce.

Enable Bluetooth in both client and server modes.
Configure and connect the WiFi to a network.
Make sure ESP32S3 is trying to connect to a server devices
With some possibility, the system crashes.

More Information.

In the ESP sdkconfig configuration, # CONFIG_ESP_COEX_SW_COEXIST_ENABLE is not set, in order to decrease wifi transmitting delay.

If enabled, WiFi & Bluetooth coexistence is controlled by software rather than hardware. Recommended for heavy traffic scenarios. Both coexistence configuration options are automatically managed, no user intervention is required. If only Bluetooth is used, it is recommended to disable this option to reduce binary file size.

updates: the server device will actively disconnect, while ESP32S3 trying to connect. Leading to this issue.

esp-zhp commented 3 weeks ago

@matreshka15 it looks that the connection was already established before create connection,and there is a PHY update onging. However, from the existing logs, I'm still unable to find the root cause. Could you provide me with a demo to reproduce this problem?thanks.

esp-zhp commented 3 weeks ago

Additionally, does the issue still persist if WiFi is not being used?

esp-zhp commented 3 weeks ago

In order to further analyze the root cause of the issue, I have added HCI logging. You can apply this patch using the git am command. 0001-add-esp32c3-s3-hci-log.zip
