CY105 Bluefruit Lab

Setup Bluefruit Board that has WHITE Connector

Install the Arduino IDE
1. Click here and then download the Windows version of the Arduino IDE.
2. Click "Just Download" on the next two screens.
3. Click the downloaded .exe file to install Arduino IDE.
4. Click "I Agree", "Next", "Install". Wait for the installation to complete, then click "Finish", which will also open Arduino IDE.
5. In Arduino IDE, click "File", then "Preferences".
6. In Preferences window, copy/paste the following into the "Additional boards manager URL":
  https://adafruit.github.io/arduino-board-index/package_adafruit_index.json
  Then click "OK" and restart Arduino IDE (close it and re-open it).
7. In Arduino IDE, click "Tools", "Board", "Boards Manager".
8. In "Boards Manager", search "Adafruit nRF52", find it below, and click "Install". It will take several minutes to install. You'll know it's complete when "Install" changes to "Remove".
9. Go to "Tools", "Board", "Adafruit nRF52", "Adafruit Circuit Playground Bluefruit".
10. Go to "Tools", "Port", then select the COM Port that says "Adafruit Circuit Playground Bluefruit" (ensure your Bluefruit is plugged into your computer, and double-press the Reset button if needed).
11. Go to "Tools", "Programmer", "Bootloader DFU for Bluefruit nRF52"."
12. Go to "Tools", "Burn Bootloader".
13. Wait for the bootloader to be downloaded onto your Bluefruit. Do NOT unplug your Bluefruit or press any buttons on your Bluefruit during this step! You will know it's complete when it says "Done burning bootloader".
14. To ensure you followed the steps correctly, open up the CPLAYBTBOOT drive and check the INFO_UF2.TXT file. It should now have a date in 2024.
15. When all these steps are complete and the INFO_UF2.TXT file has been successfully updated, return to Step 5 from the Initial Steps page and continue the instructions from there.

2. If step A doesn't resolve the issue, repeat steps 1-3 and 5-7 from the "Set up your Bluefruit board" tab in Initial Steps section of the instructions.
Display
1. Make sure all the standoffs on the display are flush with the pads on the circuit board. See step 4 from the "Assembly" tab in Initial Steps section of the instructions.
2. If the display does not turn on, ensure all screws are tight.
3. If a screw does not tighten and spins freely, get a longer screw from your instructor.
Servo
1. Make sure your jumper wires connecting the header to the bread board connect the right header pins to the corresponding servo pins. See step 4 from the "Initial Setup" tab in Robots section of the instructions.
2. Make sure all your header pins are soldered correctly. See step 2 from the "Assembly" tab in Initial Steps section of the instructions.
All else fails
1. Click here to download the file you will need.
2. Double-click the reset button on the board to bring up the CPLAYBOOT drive.
3. Drag the CP_Bluefruit_QSPI_Erase file you just downloaded onto the CPLAYBOOT drive.
4. The status LED will turn yellow or blue, indicating the erase has started.
5. After approximately 15 seconds, the status LED will light up green.
6. repeat steps 1-3 and 5-7 from the "Set up your Bluefruit board" tab in Initial Steps section of the instructions.
