I am new to this forum - please forgive any "noob" questions..
We have recently moved from a 2.4G Xbee to 868 (LP), using AT transparent point-to-point mode. On the 2.4G unit, we could set any arbitrary source address in software; on the 868 we can only use the ROM based module serial number.
In terms of in the filed replacement, this is now very inflexible; with the 2.4G unit, we could swap in a new device, the system software could just program up the same source address, and the link was back up and working.
With the 868, if a unit fails, the software at BOTH ends has to be changed (to reflect the hard coded addresses of the 2 modules). The grade of personnel required to do this has also changed....
We might be able to use the NI \ NO commands to make an "over the air" pairing of the units, but this requires physical access to both ends of the link, performing the pairing within a time period (not always easy on a mass transport vehicle installation), etc.
The use of hard coded source address could have been made optional by making the ROM serial number available in a read-only register, then allowing the user to <choose> to place it in a source address register... (all via AT cmds)
Is there a variant of the 868LP software with programmable source address?
Is there a "how to " guide for the NI \ NO command pairing procedure?
Is it just us that finds this hard coded source address a dreadfully inconvenient retrograde step in the Xbee development path ? Or am I missing something?
