WiFi 6 click
From MikroElektonika Documentation
WiFi 6 click is a mikroBUS™ add-on board with Bluegiga's WF121-A self-contained Wi-Fi module.
With a fully integrated radio and 32-bit microcontroller, this module is ideal for embedded applications.
The module's 2.4GHz band radio is fully compliant with IEEE 802.11b/g/n and offers excellent radio
performance. Allows end user applications to be embedded onto the integrated PIC32MX695H, a 32-bit
80MHz microcontroller with 128KB RAM and 512KB Flash memory, for development of lower-cost
and smaller sized products. Also integrated on-board is a single power supply.
WiFi 6 click communicates with the target MCU through the mikroBUS™ UART (TX, RX), SPI, or
IC2, with additional functionality provided by CTS pin (in place of default mikroBUS™ INT pin); a
mikroProg connector allows to update the firmware of the internal PIC32. SPI interface can be accessed
by jumpers on the click board. The board is designed to use a 3.3 power supply only.
Features and usage notes
◾ The integrated firmware provides Wi-Fi and
networking stack services (TCP/IP, UDP, DHCP,
DNS).
◾ BGAPI host protocol for modem like usage.
◾ BGScript scripting language or native
C-development for self-contained applications.
◾ On-board 32-bit embedded PIC32MX695H 80MHz,
128kB RAM and 512kB Flash memory MCU.
◾ TX Power: +17dBm
◾ RX Sensitivity: -97 dBm
◾ Automatically powers on RF circuitry only when
needed for power saving functionality.
◾ PIC32-series 32-bit MCU on module can reach a
performance of 125 DMIPS while keeping low
power consumption.
◾ Bluetooth coexistence system allows co-located WiFi and Bluetooth devices to be aware of each
other, WF121-A supports sharing the integrated antenna or antenna connector with a Bluetooth
device through the BT_RF pad.
◾ I2C, SPI and UART interfaces.
◾ mikroProg connections for updating firmware for the on-board PIC32.
Programming
This snippet shows how easy it is to connect to the WiFi 6 click and begin communication.
void main ()
{
//TFT display output initialization.
init_TFT();
//USB UART initialization.
UART1_Init(115200);
show_status("\r\n**************************",1);
show_status("UART1 initialized",1);
//WF121 UART initialization.
init_WF121_UART();
//Initialize BGLIB with our output function for sending messages.
BGLIB_INITIALIZE(uart_output);
//Send a Hello command to verify the serial port is working.
goto_state(wlan_state_hello);
}
