PMWF01A : Wifi Remote I2c Module

Quick Start Guide

Hardware Setup

Hardware Setup
  • Make sure that the driver for USB/UART Programming/Console Adapter (PMPROG01) is properly install and the PC is detected it as Comm Port.
  • The USB/UART Bridge is base on Silicon Lab CP2012 chipset.
  • USB/UART Programming/Console Adapter (PMPROG01) driver can be Download here
  • Connect the USB/UART Programming/Console Adapter (PMPROG01) to the Wifi Remote I2c Device.
  • You can power-up the WiFI Remote I2c module through the USB Bus for configuration and programming.

Setting Configuration

Termite Setup Screen
Help Command
  • For windows system, you can use terminal emulator program Termite to configure the device.
  • Termite can be downloaded at CompuPhase Website
  • Make sure the 'Port' setting is refer to the USB/UART Programming/Console Adapter (PMPROG01)'s Virtual Comm Port.
  • Follow the setting according to the setup screen capture. (57600Baud 8-N-1)
  • Once Termite configuration is done, press 'OK' to save the setting.
  • On the Wifi Remote I2c Device, Press the configuration button to allow the device to go into configuration mode.

caption Press Config Mode button to go into configuration mode

  • Type 'help' to show the command available for configuration.
  • Type 'show' to list out current configuration.
  • We will use PineA64 as our Wifi Remote I2c module's server.
  • To Set the PineA64's IP address in to the device, enter (we will be using IP address 192.168.0.230 as example)
  server 192.168.0.230
  • To configure the Wifi AP SSID and Password, (eg SSID=TestingWifi and Password=12345 )
  wifi TestingWifi 12345
  • The SSID and password are case sensitive. Please make sure it is input correctly.
  • Once configuration is done, type 'exit' to exit configuration mode and allow the device to reboot.
  • Please make sure your network is has DHCP server. The WiFi Remote i2c module will be running on DHCP mode and will requesting a IP address from your network's DHCP server.
  • After reboot, the Red LED indicator will start to blink in fast blinking mode.
  • Once the WiFi Remote I2c module connected to the WiFi Access Point, the LED indicator will go into slow blinking mode.
  • The hardware configuration is done.
  • The next step will be configure the PineWifiServer into your PineA64 board.

Setup the PineWifiServer

 chmod +x PineWifiServer
  • Start the PineWifiServer by
 ./PineWifiServer
  • Once the server is started, you will notice that the LED indicator on the Wifi Remote I2c Hardware will change from slow blinking to always on.
  • To login into the server, telnet into localhost port 10000
 telnet localhost 10000
PineWifiServer Login Screen
  • To show current connect Wifi Remote I2c type 'list' in small capital letter.
  • To see all available command, type 'help'.
  • To exit the console, type 'exit'.
  • Please take note that you are only allow one login simultaneously. The second telnet login will be rejected.

Running the WifiAppDemo

  • Download the PineWifiServer from the Download Section
  • Copy WifiAppDemo xxxxxxxx.gz into your same PineA64 board that currently running with PineWifiServer. (where xxxxxxxx is the version number)
  • Unzip both of the file using gunzip.
  • Add Execution flag on both of the file by
 chmod +x WifiAppDemo
  • before start running the demo application, please logout any telnet session to the PineWifiServer.
  • The demo application will telnet into the PineWifiServer and start polling all the available Wifi Remote I2c device currently connected to the server.
  • The demo application will also poll the I2c port of the hardware for the Ambient Light Sensor and the Temperature/Humidity Sensor if the sensor is connected to the Wifi Remote I2c module.
  • To start the WifiAppDemo, type
 ./WifiAppDemo
  • The Application will connect the PineWifiServer currently running in the localhost.
