Installing Guide

Estimated time: ~ 20 minutes

1. Download the Arduino IDE and install it. (Install Guide)

2. Add the needed libraries. (ESPNow-HelloWorld/Installation/..)

   • ESP8266 (How to add libraries)
   • Color      (How to add .zip - libraries) (The library is in the installation directory)

3. Connect the ESP8266 that will be the server host to your PC.

   • Make sure your tool settings are correct (Port could be different)

   

4. Open the GetServerMac program in the IDE

5. Upload the program to the ESP. (Ctrl + U)

6. Open the serial monitor. (Ctrl + Shift + M or Tools -> Serial Monitor )

7. Copy the AP MAC and the STA MAC from the console to the Server-Mac.txt file.
   (There should be enough time, but if you have not received a printout on the monitor, press the reset button on the ESP)

   Console Output Example:
   ===========================================================
   Gameserver
   -----------------------------------------------------------
   This node AP mac:  AF:FA:BC:02:E6:CD
   This node STA mac: AC:FA:BC:02:E6:CD
   ===========================================================
   

8. Open the ESPNow-HelloWorld program with the Arduino IDE.

9. Change the server Mac addresses for the targets in the code (don't just copy the entire mac.txt file)

41      // server esp mac addresses for the targets
42      #ifdef TARGET
43
44       uint8_t GAMESERVER_ap_mac[]   = {0xEE, 0xFA, 0xBC, 0x0C, 0xE6, 0xAF}; 
45       uint8_t GAMESERVER_sta_mac[]  = {0xEC, 0xFA, 0xBC, 0x0C, 0xE6, 0xAF};
46
47      // init sensor val
48      int initVal;
49
50      #endif

10. Comment out the target mode as follows:

25    // unwanted modes should be commented out
26    #define DEBUG
27    //#define TARGET
28    #define SERVER

11. Upload the code to the server ESP. (Ctrl + U)

12. Connect the ESP8266 that will be the targets.

13. Comment out the server mode as follows:

25    // unwanted modes should be commented out
26    #define DEBUG
27    #define TARGET
28    //#define SERVER

14. Upload the program to the ESP. (Ctrl + U)

15. Software installation completed.
