Hi, I'm trying develop a project with my ESP32-S3 as the main controller and an LTE daughterboard to connect the internet. I'm facing an issue with system crash, when I try to send a large amount of data (>2KB). On the daughterboard side, the data transfer is based on ITC frame link layer protocol, ...

Can you provide more info on how your S3 bucket is configured? error "No server verification option set in esp_tls_cfg_t structure" suggests that you require a SSL/TLS certificate to make the connection. you have set the .cert_pem = NULL, pointing to no certificate. try using the default esp_crt_bun...

If anyone is facing the same issue, here are some insights to overcome this. 1. Go to SSL Labs Server Test online and check all the cipher-suites that is supported by the server. 2. you can either disable the hardware MPI (bignum) acceleration in the menuconfig or move some ISR to a different core, ...

Please refer to the more detailed logs below: I (733475) MQTT: ########## ########### ########### I (733515) mbedtls: ssl_tls.c:3919 => handshake I (733515) mbedtls: ssl_msg.c:2358 => flush output I (733515) mbedtls: ssl_msg.c:2367 <= flush output I (733525) mbedtls: ssl_tls.c:3838 client state: MBE...

I disabled the following option in menuconfig: Enable hardware MPI (bignum) acceleration which seems to have stopped the system crashes and the interrupt error. But now the server handshake is failing with the following error even after certificate verification success.

Hi, The HTTPS connection is refused with the above error code. The connection was working fine and was able post some request to the said server, but after adding some mqtt bits (no relation to https), I'm getting the following error as shown in image. As you can see, the certificate is verified but...

Hi, I'm trying to send a POST request to a server using my ESP32-S3. The HTTPs connection was working fine until I added some of the mqtt broker connection bits. I'm using the esp_crt_bundle to verify the server. As you can see from the logs, it shows certificate verified, but the connection is fail...

can you please provide more info on disabling hardware encryption?
