Figure 18. Multi-SSID with STA
Notes:
This function is user selected factory setting and RELD instruction will not effective for this
function. If user not requires this function, the default factory setting is support one SSID when
works at STA mode. Contact with Hi-flying for more detailed support.

2.4. UART Auto-Frame
HF-A11x support UART auto-frame function. If user select open this function and setting auto-
frame trigger length and auto-frame trigger time parameters, then module will auto framing the
data which received from UART port and transmitting to the network as pre-defined data
structure.

¾ Auto-frame trigger length: The fixed data length that module used to transmitting to
the network.

introduction.
2.5. Address Binding
HF-A11x module supports the feature of binding the BSSID address of target network.
According to the provisions of 802.11 protocol, different wireless networks can have a same
network name (i.e. SSID / ESSID), but must correspond to a unique BSSID address (i.e. MAC
address). Illegal intruders can create a wireless network with the same SSID / ESSID, it will make
STAs in the network to join to the illegal AP, thereby and then network leakage happen.
Users can prevent STA from joining to illegal network by binding the BSSID address, to improve
wireless network security.

2.6. Ethernet Interface Communication
HF-A11x module provides one 10/100M Ethernet interface. With this Ethernet interface, user can
easily realize the three interface (WiFi, UART, and Ethernet) intercommunication and networking.
HF-A11x module can configured as Bridge Mode or Router Mode base on different networking
technology.
Notes: For different networking requirement, HF-A11x may need different firmware to support
this function (Such as “N-Ver” and “Z-Ver” as following, which need customized firmware as
