I purchased some XBee-PRO 868 modules () for the research project I am working with.
The datasheets and flyers from digi mention the term “mesh” and “peer-to-peer”, e.g. http://www.digi.com/pdf/ds_xbeepro868.pdf.
In the last 2 weeks I tried to figure out how to send packets from one node to another via multiple hops. My testing setup is the following: A, B and C are XBee-PRO 868 modules with XBP08-DP firmware version 1061 configured in API-mode 2. All nodes are “Standard Nodes” (CE==0).
A <-> B <-> C
A is in range of B, B is in range of C but A is not in range of C. Sending data form A to B and from B to C works pretty well but I did not manage it to send data from A to C via B with an additional hop.
How do I have to configure the modules to get an peer-to-peer topology with multihop capabilities?
Would anybody help me with this? I really got stuck with this…
With the current configuration I have a strong suspicion that these modules are not able to form a real “mesh” or “peer-to-peer” network but just a point-to-multipoint topology. In this case I would strongly advice digi to change all the promotional material including datasheets etc. because the terms “mesh” and “peer-to-peer” suggests a capability which actually does not exist!
