Stack Smashing protect Failure - getCharacteristics( )

[rlghd03]

Hello, I am a beginner of developing the BLE interface with ESP32 dev. module. Recently, I am coding to get a measurement data from a Mitutoyo vernier calliper via BLE. Searching and connecting the vernier and searching for the measurement service UUID are successful. But during searching for the measurement char. UUID by getCharacteristics( ), "Stack Smashing protect Failure" error occurs and the ESP32 reboots. The BLE library and version == ESP32 BLE Arduino by Neil Kolban Version 1.0.1 Please refer to the attached files for details. Thank you for any help. ESP32_Mitutoyo_I2C_230302.txt
