Overview
WIFI232-B2 is a high performance UART WiFi module with shield case and external antenna. It is designed for occasions where large data flow is required and power consumption will not be a concern.
1. Easy to use: just like a simple UART module (AT commands provided)
2. Start up time: 6s (most WiFi modules in the market require more than 6s to start up, even up to 30s)
3. Power consumption: 164mA-305mA@3.3V (suit for non-battery applications)
4. Shield case: protects the core circuit (usually no shielding for most other modules)
5. Ideal hotspot: supports connecting plenty devices, supports route/bridge modes (router AP solution)
6. TCPB function: supports 2x TCP, two network connections at the same time (rare feature in the market)
1. Solution: Marvell WiFi (router solution, hardware AP), ARM
2. Wireless LAN protocols: IEEE 802.11 b/g/n
3. WIFI security algorithms: WEP/WPA-PSK/WPA2-PSK
4. Working modes: STA/AP/STA+AP (AP means WiFi hotspot, STA means terminal device)
– AP mode: up to 32 devices
– STA mode: server allows 32 connections
– AP+STA mode: AP allows 32 clients with route function
5. Multi network protocols: TCP/UDP/ARP/ICMP/HTTP/DNS/DHCP
6. Support DHCP, to allocate IP automatically
7. Support AT+ instructions set and Web configuration
8. Support Transparent/Agreement transmission modes, 4K TCP cache, totally 1M cache
9. Support configuring UART framing delay and data volume
10. Up to 460800bps baudrate, supports hardware flow
11. Support Ethernet data transmission, PWM output, GPIO control
12. Firmware is upgradable via web
13. Embedded PA, bi-transferring data on 57600 baudrate without packet loss, easily pass through three concrete walls
14. Communication distance: (Between two modules under open and wide environment)
– 280 metres with external 3DB antenna
– 200 metres with onboard antenna
15. Support factory reset: pull-down the Reload IO port for 3s, restore the module to its factory settings immediately
16. Support route/bridge network architectures (thanks to the router solution)
17. Built-in watch dog and heartbeat mechanism to keep online
1. Test software for WINDOWS, iOS, Android
2. Communication example source code for iOS, Android
