Hi, I’m using a modem to communicate with 6 other radios. Currently I see none of them online, I suspect that all 6 are not dead. I reset the modem and then tried an ATDB command which returns 0. Question is, is there any way to tell if my receiver / transmitter are good without connecting to another modem. Does the ATDB command relate solely to the signal strength from the last received packet or is it an indication that my radio or antenna may be bad?
The Digi XBee products are quiet products by nature. That means that unless you are sending data, the DB value will be 0 on the receiving side. What I would suggest is connecting one of them to a PC and then run a range test. When doing the range test, make sure to use the Cluster ID option otherwise you will need to connect a Loop back adapter on the remote radio.
