Forgive me for being a newbie to XBees, but I have an issue I haven’t solved yet despite lots of reading the manual and Googling…
I upgraded my XBee units to the ZB firmware, 2 routers and one coordinator (2121, I think). I can send messages fine from the routers, but anything I send from the coordinator is not sent and echos back to the coordinator received buffer… the “router” units never see it.
Is there a config flag I accidently set here? Clues?
Thanks for any insight you can provide, and best regards…
what is the destination set to?
I obviously didn’t RTFM close enough…
Sorry. This whole ZB Mesh thing is new to me. I didn’t realize that the 2.5 modules didn’t work the same as the 1.0 ones until after I had made my purchase, and now I’m determined to make it work. I’ve got to believe this new version is better… I’m still struggling with the learning curve.
Thanks for pointing me in the right direction… on 2 counts. (1)… I installed the API firmware inadvertently instead of the AT. (2) I didn’t notice there was a DN command…
if you don’t need meshing (relays) then convert these modules to the Digi serial port extension firmware. You can convert to/from as I recall, and as you could with the version 1 modules.
With the wireless serial port extension firmware, you just tell the node what the desired one-hop destination address is and send data as if it were a serial port. Or use an all-ones address to send the data to all in-range nodes. Then based on the payload content, nodes can accept/ignore the data.
I will have to look at the manual for that firmware - also not familiar with it. Thanks for the lead! I really don’t need the meshing, but I thought it came part-and-parcel with the 2.5 hardware…
If you have the 2.5 hardware, it is mesh-oriented (Ember’s design). But I think that Digi made a series 2 compatible version of their serial port AT command firmware used with the series 1.
Originally, the series 2 were ZigBee mesh ONLY and could be nothing else, perhaps due to the legal hassles with Figure8/TI/Freescale.
