XBee Mesh networking

Sorry for the late reply but i want to use the XBEE-Pro modules

I suppose Zigbee modules, right?

Well, you do not have to do alot, jut connect them and you have established a network. Data-in, Data-out.

You just have to make one module co-ordinator. If you buy the Dev-kit things are much simpler for the set up.

You can also use the CC2500 chip from TI. Not Zigbee but if you only need to send data inside your own developed network it should work. Of course a bit difficult to get started with but worth it.

I'm Using the XBEE modules from DIGI.
When I set one module as co-ordinato, I have to use the API for communication. Only then its possible to use sending and receive addresses. (correct me if i'm wrong).

Data IN / Out is already done.

[Ioannis]

Setting a co-ordinator does not have to do with API.

You have to use API for special data handling, remote configuration or other specia functions.

OK, maybe I did not understood what you are up to.

Please detail what are you trying to do exactly.

I have 50 temperature sensors, what I need is that all the 50 sensors sends there data to one Central unit. This unit will put all the sensor data in a MYSQL database.

When I setup peer to peer communication (what have the fastest startup from a cold start, I turn down the power of the sensors) all data from all the sensors will go to each other.

I like to have that all the sensors send there data only to the host not to the other ones.
