AT Command Manual for Firmware L23
Host CPU
Multiplexing: Several sockets can be operating at once. The +WIPDATA command allows the
temporary identification of the UART in data mode with a given socket. The data written on the UART
is transferred through the socket. The data which arrives on the socket can be read from the UART.
In AT mode, the host receives an unsolicited event when the data arrives on the socket.

Sockets Identification

Sockets are identified by a pair of numbers: the first one identifies the protocol; the second one
identifies a given socket of the protocol.
9.2.1.1. Possible Protocols
The possible protocols are:
1 = UDP
2 = TCP in connect mode (Client)
3 = TCP in listen mode (Server)
Two pairs with different protocol numbers but the same index identifies two distinct sockets.
Example: Both 1,7 and 2,7 are valid identifiers simultaneously; the former identifies a UDP socket and
the later, a TCP connected socket.
9.2.1.2. Number of Sockets
The number of sockets per protocol is limited and are listed as follows.
UDP : 8 sockets
TCP Clients : 8 sockets
TCP Servers : 4 sockets
