Does somebody has experience with implementing the MbedTLS with the BLE devices. I have few questions about setting up the read and write call back functions for the mbedtls_set_bio() functions. I wanted to use the GATT api functions to set up the tunnel with MbedTLS. I am completely new to the mbedTLS and the BLE. I am not quite sure about how to set up these call backs and what exactly they should do. I am using the dialogs DA14695 USB sticks to implement the DTLS handshake between the two BLE devices.
Thanks in advance.
