Unable to compile the Arduino example

[delboy711]

I have just came across your interesting and very young project, and started off by compiling the examples.
The ESP32 example compiles OK for ESP32C3, but when compiling the Arduino example for ESP32 in PlatformIO I get a number of compiler errors.

In metadata.cpp there are a number of calls to a void function to initialise an int value. For example

int return_code = mbedtls_sha256_update(&this->sha256_context_, &end_tag, 1);

In authenticator.cpp at line 154 too many arguments are given to function mbedtls_pk_parse_key()

            &this->private_key_context_, private_key_buffer, private_key_size,
            password, 0, mbedtls_ctr_drbg_random, &this->drbg_context_);```

I have an ESP32C3 on order and shall certainly be trying  your project out on it when it arrives, but it would also be nice to be able to compile for ESP32 as I have lots of them.

Thanks for the project.

Hey @delboy711,

Yeah that's the case because the Arduino env uses mbedtls2 and the platform io library is made for mbedtls3. Check the readme there is an example on how to run the code with Arduino. Basically you have to modify the source code by applying a patch to downgrade the code.

Let me know if you have more questions.

How do I build and burn to esp32
