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-9508-19A6F6B356 for SSID characteristic.
Step 5: Find the UUID: 40B7DE33-93E4-4C8B-A876-D833B415A6CE for Password characteristic then procedure as Step4.
Win7 PC
Prepare a win7 PC.

- 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.
- Connected to PC via a micro USB cable, the Device Manager will appear mbed Serial Port
