Further: tracing through the code, with altcp.c, altcp_tcp.c, and altcp_tls_mbedtls.c enabled, looks like the flow of control is this
mqtt_client_connect calls altcp_connect, which using the indirect table, calls altcp_mbedtls_connect, which calls altcp_connect again, with the "innerconn" atlcp_connect this times, calls altcp_tcp_connect, which basically just calls tcp_connect So am I correct to think that this chain completely replaces the mbedtls_net_connect call? The problem I have is that the callback function originally supplied to mqtt_client_connect never gets called. On Fri, Aug 3, 2018 at 11:34 PM, goldsimon <[email protected]> wrote: > > > Am 4.
