Re: DTLS handshake never ends successfully

Any ideas? :) FYI, dlts_static is a byte array that allows allocating the resources needed by DTLS statically by the caller (in other words, without heap allocation) and, at the same time, hiding the internals of the actual structure underneath. Therefore, this opaque structure is only valid as long...

DTLS handshake never ends successfully

I want to connect an ESP32 to a DTLS server using mbedtls' dtls_server demo. The code I used for the client is very similar to the dtls_client example, but is unable to finish the handshake process for some reason.

Error BT_BTM: Device not found after few seconds after successful connection

Hello, I want to implement secure communications between an ESP32 and a smartphone using BLE. Since the board with the ESP32 does not have display or input capabilities, I guess ECDH key exchange with no MITM protection (OOB is not an option) is the safest level. OTOH, I am not interested in storing...

Some progress was made to remove this limit a while back, but unfortunately it hasn't been completed yet.
Is there any progress on this? I'm interested in this limitation to be removed.
