XBEE API MODE communication

[vvnayak]

I am using xbee s2c in api 2 mode to transmit data using LABVIEW to another xbee connected to xctu or arduino uno. I am able to write the frame on xbee connected to labview using VISA write function but it is not transmitting.

I am generating a hex array of the frame and then sending each element of array one after another like 7E then 00 then 10..using VISA Write.

Please help me to solve this.

This is the block diagram from writing the api frame generated. 

Note: Red crossed line is not included in the final block diagram.

Hi

Are you sure you really need HEX, why not binary. In fact why send the hex (ascii in fact) representation of a byte when you can send the byte yourself?

I have no idea what will work. I just tried to generate a frame similar to the one generated in XCTU and there a hex frame is generated. If sending binary can work i will try that.

Thanks.

Hey

As u suggested i tried sending the bytes i.e. instead of sequence 7E..00..12..and so on, I am sending decimal equivalent 126...0..18..so on. But still i am not getting any output.

Please give me some solution.

Hi

I suggested to use the value of the character instead of the decimal interpretation.

You can convert a decimal value to a character by filling an array of bytes with decimal values and then convert this array into a string again. It seems a lot of work but in fact is easy.

If necessary post your vi and I will change it, but remember I don't know your XBEE part.

So if documentation about that part is available, send it also.
