NimBLE Stack smashing detected (IDFGH-14652) #15398

florianhumblot · 2025-02-14T21:10:25Z

Answers checklist.

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

IDF version.

v5.1.4-674-gd38afc77db

Espressif SoC revision.

ESP32-C3 (QFN32) (revision v0.4)

Operating System used.

Linux

How did you build your project?

Command line with idf.py

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

None

Development Kit.

Custom Board

Power Supply used.

USB

What is the expected behavior?

When connecting to a NimBLE application on the ESP32C3 I expect to be able to connect without a crash.

What is the actual behavior?

The device crashes with a instruction access fault, unless I enable stack smashing detection, which then shows up in nimble

Steps to reproduce.

Connect using python Bleak:

import asyncio
from bleak import BleakScanner, BleakClient, BleakGATTCharacteristic
import logging

logger = logging.getLogger(__name__)

async def main(name):
    device = await BleakScanner.find_device_by_name(
        name
    )
    if device is None:
        logger.error("could not find device with name '%s'", name)
        return
    async with BleakClient(device) as client:
        await client.connect()
        


if __name__ == "__main__":
    asyncio.run(main("myDevice"))

Crash :)

Hi @florianhumblot,

I tested this scenario using the IDF example bleprph and attempted to connect using python Bleak, but I did not encounter any stack smashing on my side.

Could you kindly share a minimal example code based on IDF examples that reproduces this issue? This would help us run it on our local device and analyse the behaviour more effectively. Additionally, it would be helpful if you could provide a detailed step-by-step description of how to reproduce the issue, including If you made any changes to sdkconfig , please include those as well so we can replicate the setup accurately.
