AT+CWMODE=3 – dual mode

The third possible mode for the WLAN setting is dual mode. As the name sug-

gests, it permits operating the module in station and AP-mode. This means that

devices can establish a direct WLAN connection to the module, or reach the mod-

ule through the router as an interim station. It is a practical mode, e.g. when you

are planning an internal network with several

modules, but want one module to serve as the

server that supplies all data to the network. We

will get back to this later.

the Baud rate, were deliberately left out, since they may

render the module useless.
