TOOL AND DEVELOPMENT ENVIRONMENT SETUP

2.4G Wi-Fi AP SETTING WITH BLE APP

Ble-WiFi introducer service is a demonstration that set SSID and password to join network by phone. EVK will launch a BLE GATT server and advertise itself.
Then you need to manipulate on your phone.

Step 1: Install and launch the BLE Scanner app on iOS or Android.

Step 2: Pull down the screen to rescan devices and it will list nearby BLE devices. Find the “WiFiInt” device and press CONNECT button.

Step 3: If the connection is successful, you can see the picture below. Press the "CUSTOM SERVICE" button.

Note: You need to remove bluetooth pairing with "WiFiInt" from bluetooth setting when you can not connect to device.

Step 4: Find the UUID: ACA0EF7C-EEAA-48AD-9508-19A6CEF6B356 for SSID characteristic.

Step 5: Find the UUID: 40B7DE33-93E4-4C8B-A876-D833B415A6CE for Password characteristic then procedure as Step4.

Step 6: If the join is successful can see network IP on console screen.

Win7/10 PC

Prepare a win7/10 PC.

TFTP DOWNLOAD/UPLOAD FILE

Make sure PC connect to 2.4G Wi-Fi AP and get IP address
Recommend used tftpd64
Set the process reference link https://www.youtube.com/watch?v=YdVEonLMWYs

Python Environment Setup

Download and install Python (must use Python 2.7.x Windows x86)
Set the variables of Widows environment path: add “C:\Python27;C:\Python27\Scripts” to path
Download and install python PIL package
Download and unzip picture transformation tool "BmpToPixel_EPD-132R.py"

Bmp Image To EPD Format

Run BmpToPixel_D73.py <source BMP image filename> <output filename> in cmd window
- source BMP image filename: the image file to be converted
- output filename: converted file name(recommend to use "esl" as the extension)
- Bmp size must comply with EPD resolution 1600 x 1200
- Bmp file: mono color/16 color/256 color/24bits bitmap format
- Ex: BmpToPixel_D73.py EVK_03.bmp EVK_03.esl
Type BmpToPixel.bat to use batch conversion in directory
Copy output files to tftp Base Directory

WISE-ED22 Setup

Download and install WISE-ED22 driver
Update WISE-ED22 FW for EPD-132 project. You can reference ED22 Firmware Update.

Download Images to EPD-132 &REFLASH IMAGE

DOWNLOAD THE IMAGE

tftp <ip> <filename> <flash index> [-r]

ip: tftp server ip
filename: image file name
flash index: range 0~3, that have maximum 4 images(0~3) be saved in flash
-r : immediate refresh after download complete
Ex: tftp 192.168.8.178 example_2.esl 1 -r

DOWNLOAD THE IMAGE

epd_disp <-f flash index | -i internal image index>

-f: display image that read from flash, range 0~3
-i: display internally generated image, range 0~4
   0: fully black
   1: full white
   2: full red
   3: black/white/red vertical stripes
   4: black/white/red horizontal stripes
Ex: epd_disp -f 1
Ex: epd_disp -i 4

EPD-132 Carousel Mode

carousel<-e | -p | -s | -t >

-e <1 / 0 > : set carousel mode
- 1: enable, 0: disable
- Ex: carousel -e 1 // enable carousel mode.
