Closing sockets

I'd like to understand this a little better.

In the driver, you've specified that the radio can have 5 socket connections. The following is copy and pasted from the MXChip MiCO-AT Firmware Reference Manual:
TCP/UDP management commands
1 AT+CON1 Query/set parameters of TCP/UDP connection 1
2 AT+CON2F Query/set whether to open TCP/UDP connection 2
3 AT+CON2 Query/set parameters of TCP/UDP connection 2
4 AT+CONF Query/set whether to open or close TCP/UDP
5 AT+CONS Query TCP connection status
6 AT+CONSN Query/set connection numbers on TCP server

1,2,3, and 4 are of interest. It looks like there can only be 2 socket connections open at one time. However, it looks like the current driver only uses CON1. This is causing some issues when I am running networking tests. Here, you can see that the id parameter is not used at all, so we are only assuming ONE socket connection in the driver when we close a socket.

I am going to investigate this a little further and try to resolve it, but I wanted to file an issue and start a discussion here.

Current EMW3080 AT-Command firmware only support TWO sockets connections with two . We are coding a new firmware version to support multiple sockets use single connection command set.
We plan to finish this firmware coding this week, and update a new mbed driver next weak
