[ESP32] esp-wifi crashes when trying to connect via BLE #441

I have also encountered these additional errors, but cannot reliably reproduce them for now: |

Can you run the provided examples without issues? both of the crashes sound a lot like stack or general memory corruption to me |
The ble examples work fine. I also had all parts of my own code working before, reading the sensor and connecting via bluetooth. But when I try to put it all together, I end up with these errors.
Edit: I have been able to make it work, but only by stripping out all asynchronous and embassy-related code. And it’s still very shaky, e.g. once I check if the value changed before sending a notification it breaks again. |

Ok looking again there is one obvious thing in the code - nothing weird and explainable. // Define service methods
let mut read_sensor = |_offset: usize, data: &mut [u8]| {
// Try to get last reading, otherwise send 0.0
if let Ok(value) = SENSOR_READING.try_receive() {
data.copy_from_slice(&value);
} else {
data.copy_from_slice(&[0u8; 4]);
}
4
};The // Define service methods
let mut read_sensor = |_offset: usize, data: &mut [u8]| {
// Try to get last reading, otherwise send 0.0
if let Ok(value) = SENSOR_READING.try_receive() {
data[..4].copy_from_slice(&value);
} else {
data[..4].copy_from_slice(&[0u8; 4]);
}
4

@bjoernQ thanks, I already found and fixed that yesterday. Didn‘t notice it was still in here. |

I guess we can close this issue now |

Context
I’m working on a project using embassy and the esp-wifi crate for BLE.
I use a Lolin32-lite board with an ESP32 Rev1.
Unexpected Behaviour
When I try to connect to the ESP32 from my Android phone, the ESP32 crashes with the following error message:

Here’s my code to reproduce the issue:
