Related to an "XBee-PRO SX" module, firmware version '9003', hardware version '3104', hardware series 'A00'.
I am using this module with the API frame mode and am attempting to set parameter values in it via the 0x08 "AT command frame". I have written custom code to talk this the radio. I have had success with setting the parameters 'ID', 'HP', and even querying 'NP'. I have seen return packets that confirm that the command was successful and have verified that using the XCTU software to then read the changes I made.
The problem I am having is with the 'BR' and 'AO' parameters. I inserted those two settings into my code in the same fashion as the previous parameters that I've had confirmed success with. I see no response from the radio to those commands, not even a 'command failure' response. When I was working towards setting the parameters that I've had success with, I would see a 'command failure' packet related to the tagged packet I'd attempted.
For 'BR' and 'AO' I have tried multiple ways to encode the values. I first copied what worked with 'ID' and 'HP'. I then adjusted each one between 8 and 16 bit values. I tried sending the value as ASCII decimal, with multiple variations. But I have yet to see a response to these packets from the radio.
Insights or suggestions?
Please re-categorize if appropriate; I did not see 'SX' type radios in the list.
