Signal

!Screenshot_2022-08-18_21-23-22.png

  • First step is to analyse the signal (Frequency and modulation)

  • Second, setup the parameters in the Arduino Roll file

    • Frequency
    • Jam Frequency
    • Jam Power
    • ...

➡️ MORE INFORMATION

SD Card Setup

  • Add the HTML file to the micro SD card

Device Setup (Roll)

  • Install esptool: sudo apt install esptool
  • Install pyserial: sudo pip install pyserial
  • Download and Install the Arduino IDE: https://www.arduino.cc/en/main/software
  • Download Evil Crow RF V2 repository: git clone https://github.com/joelsernamoreno/EvilCrowRF-V2.git
  • Download the ESPAsyncWebServer library in the Arduino library directory: git clone https://github.com/me-no-dev/ESPAsyncWebServer.git
  • Download the AsyncElegantOTA library in the Arduino library directory: git clone https://github.com/ayushsharma82/AsyncElegantOTA.git
  • Download the ESP32-targz library in the Arduino library directory: git clone https://github.com/tobozo/ESP32-targz.git
  • Download the AsyncTCP library in the Arduino library directory: git clone https://github.com/me-no-dev/AsyncTCP.git
  • Edit AsyncTCP/src/AsyncTCP.h and change the following:
  • #define CONFIG_ASYNC_TCP_USE_WDT 1 to #define CONFIG_ASYNC_TCP_USE_WDT 0
  • Open Arduino IDE
  • Go to File - Preferences. Locate the field "Additional Board Manager URLs:" Add "https://dl.espressif.com/dl/package_esp32_index.json" without quotes. Click "Ok"
  • Select Tools - Board - Boards Manager. Search for "esp32". Install "esp32 by Espressif system version 1.0.6". Click "Close".
  • Open the EvilCrowRF-V2/firmware/v1.3.1/EvilCrow-RFv2/EvilCrow-RFv2.ino sketch
  • Select Tools:
    • Board - "ESP32 Dev Module".
    • Flash Size - "4MB (32Mb)".
    • CPU Frequency - "80MHz (WiFi/BT)".
    • Flash Frequency - "40MHz"
    • Flash Mode - "DIO"
  • Upload the code to the Evil Crow RF V2 device
  • Copy the EvilCrowRF-V2/firmware/v1.3.1/SD/HTML folder to a MicroSD card.
  • Copy the EvilCrowRF-V2/firmware/v1.3.1/SD/URH folder to a MicroSD card. (OPTIONAL)

WIFI Setting (192.168.4.1) - (DEPEND ON THE ROLL VERSION, ROLL V.3 DOES NOT SUPPORT)

  • Connec to the RollJam WIFI
  • Go to 192.168.4.1
  • Change the setting to:
    • Set the module to (Module2)
    • Set the Frequency (Depending on the annalyse from URH)
    • Set the RxBW (Default 58)
    • Set the Deviation (Default 8)
    • Set the Data rate (Default 5)
