| Zigbee Network |

Hi,
I want to make a network having one coordinator and two sensors board. Coordinator sends data to both sensors. Have anyone any example how to make a network and sends data?
I am using CCS Ember Zigbee and CCS compiler. |

| For my Zigbee apps I'm using a module with its own Ember stack and drive the network from my PIC through AT command. |

Thanks adesport.
Can you send me some example files. |

| Code: |
ATSend("AT+DASSL"); //Disconnect ZigBee Network
ATSend("AT+JN"); // Join any ZigBee PAN
//...
|
ATSend uses PIC UART to send command to a ZigBee module.
AT command answers are catch by an ISR with the UART as well. |

| I am using "CCS ember zigbee". I brought development kit from CCS. It interfaces with pic controller through SPI. There is no option for UART. |

| So I guess CCS provides example files as usual... |

I have made a network but it is not working properly. Coordinator sends data to both sensors one by one and both sensors receive data.
Problem starts here:
When I switch off sensor 1, sensor 2 stops receiving data
but
When I switch off sensor 2, sensor 1 receives data.
I want that both sensors do work independently. Whenever I switch off any of the sensors the other sensor receives data. |

| Which kind of ZB devices are your sensor ? SED or FFD ? |

If "SED means Sleepy End Device" then I have two sleepy end devices,
and the Coordinator is acting as a FFD. |

If both your sensors are SED, their parent is your FFD. In this case, if one of your sensor goes off the other one will still be able to communicate.
Post your code to see if something is missing. |

Your code doesn't have any comment at all  nice
Did you read "Wireless-Ember ZigBee™ Exercise Book Table Of Contents" provided by CCS? There may be some example.
| Quote: | | value1=(rcvdata[x]); |
Normally, a Sleepy End Device has to poll its parent in order to get messages from the network. I can't see this in your code, but again I'm not familiar with CCS Wireless - Ember ZigBee. |

Ya I have read "Wireless-Ember ZigBee™ Exercise Book Table Of Contents". In the example SLEEPY SENSOR is sending data to the COORDINATOR, and in this example there is only one Coordinator and one Sleepy Sensor. No such example which have two sleepy sensors. I want to send data from Coordinator to Sleepy Sensors. I am only confused why one sensor is not responding when other is off. I referred to the CCS Team but they said that your code have no error.
Can you help me out or have you any examples which can solve my problem? |

| Give me a link to all the CCS Zigbee documentation. I'll check it out. |
