This issue was resolved by updating the firmware. More details here: https://github.com/espressif/esp-at/issues/563

Hey! I am using ESP32-C3 on DevKitC-02 board. I am trying to initialize BLE via AT + BLEINIT = 2 and I get this response AT + BLEINIT = 2 AT + BLEINIT = 2 ERROR At the same time, the following message appears on the UART as a channel for the logs: "Config struct mismatch: magic = 5a5aa5a5, ver = 021...

IIRC edge interrupts have some issues if the rise time is not fast enough. This github issue has a description: https://github.com/espressif/arduino-esp32/issues/4172 Thanks for the answer!
