i have been trying on mesh network using digimesh protocol, the problem is that i cant get one library for arduino. i have reading this guide:
ftp1.digi.com/support/documentation/90000991.pdf
i found that there is a library but i dont know how to use it in arduino, here is the library
https://github.com/digidotcom/xbee_ansic_library
please help
These are standard C files for microprocessors using C. What I would suggest is looking at https://github.com/andrewrapp/xbee-arduino for the library files you are looking for.
thanks for your response, i tried using this library but this wont support digimesh frames.
If it supports the Zigbee mesh for the XBee then it will support the Digi Mesh. I know this because Digi uses the same API for both protocols.
there is a difference between zigbee frames and digimesh
Xbee digimesh protocol frame for sending transmit request using '5’as payload:
7E 00 0F 10 01 00 00 00 00 00 00 FF FF FF FE 00 00 35 BE
here is the same frame for zigbee transmit request using 64 bit addressing:
7E 00 0C 00 01 00 00 00 00 00 00 00 00 00 35 C9
You need to read the API sections of the product manuals. You are going to find that it is the same.
The frames you are using a reference are not the same frames. The first is sending a packet to a Broadcast address where as the 2nd is sending data using the 802.15.4 64 bit TX request packet.
If you look between the Zigbee TX request packet and the Digi Mesh TX request packet, you will find that other than a few additional option bytes available to use, they are the exact same API.
i am using this library
//code
#include
XBee xbee = XBee();
// put your setup code here, to run once:
void setup() {
Serial.begin(9600);
Serial3.begin(9600);
xbee.begin(Serial3);
}
void loop() {
// put your main code here, to run repeatedly:
xbee.readPacket();
if (xbee.getResponse().isAvailable()){
Rx16Response rx16 = Rx16Response();
uint8_t data=rx16.getData(0);
Serial.println(data);
}
}
but i am getting wrong data, i am sending transmit request with payload 0x5 and i think i should get it using this function.
But i am getting wrong data, and its almost random
64 bit TX request packet is not available in digimesh
so here is the code for checking if the packet is valid
if (xbee.getResponse().isAvailable()) {
if (xbee.getResponse().getApiId() == RX_16_RESPONSE) {
xbee.getResponse().getRx16Response(rx16);
}
}
how do it check it in digimesh
[SOLVED]
Thanks for your help
Its now working,
xbee.readPacket();
if (xbee.getResponse().isAvailable()) {
if(xbee.getResponse().getApiId() == ZB_RX_RESPONSE)
{
xbee.getResponse().getZBRxResponse(rx);
option = rx.getOption();
data = rx.getData(0);
Serial.print(“data:”);
Serial.print(data,HEX);
}
}
thank you all its working now
Hi Waqasaps,
I’m going through a similar problem trying to get the Arduino to talk with the xBee S3B Digimesh in API mode.
Would you please post the Arduino code that you are using for sending the msg and also the code for receiving the message.
This is the code I use to in the Arduino “Sender” for sending data. In this particular case I’m trying to send a “Hi” but I think I’m getting the wrong API message in the output of the Arduino “7E01010107D33A2040B2FA4AFFFE00486955”
I use another Arduino “Receiver” to check what is coming in the serial output of the Arduino Sender. In the real application this output would be connected to the xBee module.
I think the API message that goes out of the Arduino sender should look like “7E 00 10 10 01 00 7D 33 A2 00 40 B2 FA 4A FF FE 00 00 48 69 55”
Do you see anything wrong in mi code?
I’m using Andrew’s library “andrewrapp/xbee-arduino”
