Xbee XSC binary command mode

Wireless & IoT

I have used a variety of Xbees for some time now with good success. Doing serial wire replacement, mostly just broadcast but some point-to-point with RR retries turned on. Now I need to use retries in a one-to-many topology where only the master issues a command but I need confirmation of receipt from the slave and retries if needed. And I like the 900 xsc device so far.

In studying the doc for the Xbee XSC there is a binary command mode which seems good for this - changing DT on the fly - but I need some help understanding how to get in and out of binary command mode (which does not seem to be same as Xbee API mode). It looks like you have to manipulate the level of one of the hardware pins, send the binary command data to change DT, then put the pin back in its default state before sending application data. Or maybe not - this is puzzling.

Alternatively I could code this functionality in my application code. That may be best in the long term but understanding the builtin would help greatly.

Thanks in advance.

The above is my first post here. Did I flip the bozo bit or is the question out of scope here?

no, it’s probably because very few people have the 868/900MHz XBees. I and a few others have lots of experience with the 2.4GHz products.

In the XBee 2.4GHz, I use the API mode but have no reason to drop out of it once enabled by my software at startup. Indeed, if I did drop out of API mode, incoming data from others that are in API format would confuse the radio and my application.

Thanks. I will try the manufacturers forum.

I’ve found Digi’s wireless device tech support staff very good, by phone call.
