I have just bought two back-up XBee S6B modules. I have updated the firmware from 2024 to 2026. I then wrote a previously saved config file from a working XBEE of the same type. Scrolling through all the parameters they are all identical. The module is set up as follows: AH 1, CE 2, NS 192.168.1.1, DL 192.168.1.14, NI Creater, GW 22.214.171.124, MK 255.255.255.0, MY 192.168.1.13, BD 7. Only one of these three modules is used at once. It is meant to communicate with another XBEE with the following parameters: NI Joiner, AH 2, DL 192.168.1.13 and MY 192.168.1.14. Despite the fact that I'm using a working config file the set-up is not working. Any ideas what I could be doing wrong?
