Possibility to change MTU (max_frag_len) fragmentation size. about python-mbedtls HOT 8 CLOSED

Currently, it isn't possible but wrapping mbedtls_ssl_set_mtu or mbedtls_ssl_conf_max_frag_len, or both should be simple enough.

These are the relevant options, right?

If I'm not mistaken, upstream only allows the values you already noted: 512, 1024, 2048, and 4096. So it can't be set to 380.
See, https://github.com/Mbed-TLS/mbedtls/blob/development/include/mbedtls/ssl.h#L4230C1-L4232

If I got that right ony mbedtls_ssl_conf_max_frag_len allow to use constant values. mbedtls_ssl_set_mtu allows to use any integer value.

Yes, I think you're right. Reopening.

Both functions are wrapped now in the library and they will be available in the next release. If you need the functionality faster, you should compile the library yourself, have a look under scripts/ for examples. I do not really plan to modify the example programs but that should be simple enough.
