Error when compiling: 'class CRC32' has no member named 'update'

[Tidle999]

Got this compiling error when trying to upload the sketch to my diymore ESP-WROOM-32.

`Arduino: 1.8.19 (Windows 10), Board: "DOIT ESP32 DEVKIT V1, 80MHz, 921600, None, Disabled"

SwitchBot-BLE2MQTT-ESP32.ino: In function 'uint32_t getPassCRC(std::__cxx11::string&)':

 crc.update(byteBuffer[i]);

uint32_t checksum = crc.finalize();

Good morning, replying as I was tinkering around with this at the weekend and got it working, I have found that the Arduino IDE can be cumbersome and a pain to get working, had a similar error as you and assumed it was just I hadn't got the right version of the library here or there.

I'd strongly recommend downloading VSCode and the Platformio extension (both are free) and shouldn't take more than 5-10 minutes to setup (Based on internet connection), but it took a few minutes to load the project due to the number of envs, but selected the appropriate board and compiled first time and was easy to compile and upload :)

Not exactly the answer you were looking for but should help :)
