I found problem , it was because i mistakenly connected 5 v instead of 3.3 v. (And i know it was garbage because i send it to PC's COM port for debug.)
Now Will u please suggest me weather can I use Bitcloud HA profile for my application I explained below:
I am designing a Home automation project in which there is a master and several slaves. Master and slave both will be Atmega256rfr2 operated nodes(mostly Zigbits). For one house there will be one master and there will be one slave per room.So if a house has 4 rooms so in that case 1 master 4 slaves. Every slave will have several devices connected to it like lights ,fans etc. Master will control all the devices on each room. It should send commands to ON/OFF particular light in particular room.
So as per my understanding, in bitcloud HA profile, there is only one device connected to a zigbee radio but in my application there may be several devices connected to it. So can i use bitcloud here? if yes ,How?
