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

Closed thecodechemist99 closed 8 months ago

thecodechemist99 commented 8 months ago

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:

!! A panic occured in '/Users/thecodechemist99/.cargo/registry/src/index.crates.io-6f17d22bba15001f/esp-wifi-0.4.0/src/preempt/preempt_xtensa.rs', at line 104, column 9:
index out of bounds: the len is 3 but the index is 1073503776

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

Can you run the provided examples without issues?

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.

both of the crashes sound a lot like stack or general memory corruption to me If that would be the case, what could I do about it?

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.

bjoernQ commented 8 months ago

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 data slice is 255 bytes so the correct thing would be

        // 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.

bjoernQ commented 8 months ago

I guess we can close this issue now
