This networking model is similar to the first one, except that the module establishes a
TCP Server instead of a TCP Client in STATION mode.
This model can support up to 4 remote device connections under networking conditions.
One module establishes TCP Server in AP mode and other modules establish TCP Client in
STATION mode to communicate with each other
This networking model can be referred to as intra-module networking, where a module in AP
mode can be connected to at most one STATION, and the TCP Server can be established on
any module under the completion of intra-module networking, and the remaining module can
use TCP Client to communicate with it.
