AP, this type of network is a loose structure, all the STAs in the network can communicate
directly.
As showing in the figure below, HF-A11x (1) can be treat as an AP, and HF-A11x (2), HF-A11x (3)
and the laptop are STAs connected to HF-A11x (1). Meanwhile, all HF-A11x modules can
connected to user device via UART interface. All HF-A11x modules can be operated and
managed through the laptop. So it is convenient to O&M all HF-A11x modules. Moreover, in such
Adhoc network structure, the whole coverage of a wireless network can be extended easily.

2.3. Multi-SSID with STA
HF-A11x support Multi-SSID when works at STA mode. Module can set maximum 3 AP’s SSID.
After modoule boot-up, it will auto search 1st SSID and try to connect with this AP. If 1st SSID
can’t link, it will search 2nd SSID, and then 3
After modoule boot-up, it will auto search 1st SSID and try to connect with this AP. If 1st SSID
can’t link, it will search 2nd SSID, and then 3
rd
SSID, until successful connected with one AP.
Module will query link status every 5 second when try to connect to dedicate AP. For each SSID,
user can set different encryption method.If this function is open, user can set different SSID
through web page, “STA Interface Setting Page”.
