XBee Mesh networking
Are there people who already create XBee Mesh networking. For my home sensor network I need good send / receivers. I hear a lot about XBEE pro modules. Only I can not find a good start up docuement for PICBASIC Pro.
I Like to hear good / bad experience from this forum users.

Well, I hope I'm wrong but I haven't seen much information about XBee modules and PBP either. I'm also trying to make some XBee modules work. I'm using the MRF24J40MA modules. I've been forced to use C, since I haven't found much information in PBP. There are plenty of Wireless Networking Protocol Stacks and sample programs out there in the web but all of them are in C language.Originally Posted by NL2TTL

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.

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.

Definetely the receiving node should be set in API mode. This does not mean that the receiving node is also the coordinator.
The others with the sensors should have the IR set accordingly. Also if you have analog sensors, then the input that it is connected should be ADC enabled.
Remember that the analog inputs are 0-Vdd Volts. Not 5 volts inputs.
Also each node should have a unique address.
