In particular, are they compatible with the 900 XTEND products?
Yes there are SX versions that are compatible with the old Xtend.
OK, so I have a older 9XTEND module running firmware: Product family: XTO9 Function set: 9xTEND 115K HOPPING (digiMesh)version 8064
and a new SX running Product Family: XBP9X, function set XBEE PRO SX, version 9003
Do I need to change one or the other to make them compatbile? Because the way they’re configured now, they can’t talk to each other.
Yes the SX module needs to be running the XCT Digi Mesh function set and Code.
I changed the new 900SX to
XBP9XT-DM: XTC DigiMesh: 8003
and left the 9XTEND set to
XT09: XTEND 115K Hopping (Digimesh): 8064
Still no joy – if someone could provide the details of compatible firmware on each side of the link, I’d appreciate it.
What if you change over to the Non Mesh versions of the Code? Are you then able to communicate?
