Hi,

   I am trying to send information from arduino to the xbee explorer using Xbee series-1.I am using the following code

     The serial monitor is displaying some trash. Please tell me whats wrong with my program.

Thnaku very much

[Reply #1 on:]

Read this before posting a programming question

Code tags please.

[Reply #2 on:]

Sorry i dont understand what do u mean by "Code tags please".

[Reply #3 on:]

Can u plese tell me how to modify the code to display the correct value in the serial monitor

Thanku very much

[Reply #4 on:]

Sorry i dont understand what do u mean by "Code tags please".

Please edit your post, select the code, and put it between [code] ... [/code] tags.

You can do that by hitting the # button above the posting area.

Probably nothing is wrong with the program. Most likely, you don't have the Serial Monitor baud rate set to match the Arduino's serial baud rate.

I don't see where you did Serial.begin().

Plus see reply #4.

Hi,Even though after including  Serial.begin() also it is showing some trash in the serial monitor and the baud rate is same for serial monitor also.
Can u please tell me the configuration settings of the two xbees using XCTU.

Thanku very much

[Reply #9 on:]

Code:

// Connect Arduino pin 9 to TX of usb-serial device
uint8_t ssRX = 9;
// Connect Arduino pin 10 to RX of usb-serial device
uint8_t ssTX = 10;
// Remember to connect all devices to a common Ground: XBee, Arduino and USB-Serial device
SoftwareSerial nss(ssRX, ssTX);

What Arduino are you using? My UNO does (hardware) usb-serial on pins 2 and 3 only.
But I could go softserial on 9 and 10 to a serial-USB adapter, I suppose.

[Reply #10 on:]

I am using Arduino Uno

[Reply #11 on:]

Can u please tell me the configuration settings of the two xbees using XCTU.

Can you learn to spell. You is not u.

You need to have set PAN ID, DL, and MY. What values did you set/do you have?

What baud rate are the XBees operating at?

What Arduino are you using? My UNO does (hardware) usb-serial on pins 2 and 3 only.

The ones labeled 0 and 1 on the board?

[Reply #12 on:]

@OP:  You can still go back to the start of this thread and add those code tags -  it isn't too late.

[Reply #13 on:]

Sorry i dont understand what do u mean by "Code tags please".

Did you read the thread I linked about how to post a programming question? If not, and if you are going to ignore us, I'll have to lock this thread. Sorry.

Hence my confusion over INT0 and INT1 being tied up with Serial when they're not.
I swear I go round this monkey ride a few more times and I'll either never forget or never get it right!

Yeah... Arduino pins 0 and 1, 328P pins 2 and 3, but definitely not pins 9 and 10. I'm just wondering since the code I've seen doesn't use the usual path to Serial Monitor if the screen garbage has anything to do with the wiring to get data to it. Something must go there or there wouldn't be garbage would there?
