Ok,
Background:
I have successfully gotten communication between 2 Unos using Software Serial working.
My sending station sends the numbers 1 to 100 repeating to the receiving station which outputs it to the serial monitor.
Here’s my next challenge: I want to replace this direct connection with 2 Xbees.
In each case I have the Xbees and Uno’s connected with 3 wires.
The sending station has 1 Gnd to Gnd, 1 5V to 5V, and 1 from Pin 3 to Rx on the Xbee.
The green light is flashing.
The receiving station has 1Gnd to Gnd, 1 5v to 5V and 1 from Pin 2 to Tx on the Xbee.
The green light is flashing and the red light is lit constantly.
My code for both stations is this:
#include SoftwareSerial Xbee(2,3); int i; void setup() { Serial.begin(57600); Xbee.begin(57600); } // Setup void loop() { for ( i = 1; i <= 100; i++) { Xbee.print(i); Xbee.print('T'); Serial.println(i); delay(500); } } // Loop
#include SoftwareSerial Xbee(2,3); int RecVar; int input; void setup() { Serial.begin(57600); Xbee.begin(57600); } // Setup void loop() { // delay(50); if(Xbee.available()) { RecVar = Xbee.read(); //Serial.println(RecVar); //Troubleshooting step if(isDigit(RecVar)) { input = (input * 10) + (RecVar - 48); } else { Serial.println(input); input = 0; } } } // Loop
So when directly connected, I get this:
0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
But when put through the Xbees I get this:
2 3 4 5 6 8 9 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 2 0 2 0 2 0
What’s going on here?
Thanks for any help.
