Telegesis ETRX357-LR - 1.8 Important notes

R309 AT Commands
©2015 Telegesis (UK) Ltd - 6 - AT Command Manual (Rev 3.09)
This certification includes tests guaranteeing that:
- Modules running the Telegesis AT-Command set will not interfere with existing ZigBee
Networks in a malicious way
- Modules running the Telegesis AT-Command set can join a 3rd party ZigBee PRO network
and use its routing capabilities
- Modules running the Telegesis AT-Command set can allow 3rd party nodes to join into a
network consisting of Telegesis nodes and use its routing capabilities
In addition to implementing a manufacturer specific application profile the AT-Command set allows
for transparency allowing communication with 3
rd
party nodes running any public application
profile. In addition to this a transparent endpoint has been added allowing a host processor to
implement any public application profile in fully transparent mode.
If you want to use the term ZigBee or the ZigBee Logo in your product documentation the current
regulations state that you have to
(i) Be at least an adopting member of the ZigBee Alliance in the year you release your product
(ii) Implement a public application profile
If you intend to get your product certified feel free to contact Telegesis for additional information.
Also if you intend to build a product compliant to a public application profile (e.g. Home
Automation, Smart Energy) feel free to contact us to discuss your options.
1.8 Important notes
1.8.1 Hardware compatibility
R2xx firmware will not run on the ETRX3 series of modules.
1.8.2 Unexpected start-up in bootloader mode
The bootloader in the ETRX357 can be triggered using the command AT+BLOAD as described in
section 2, but it can also be triggered in hardware. If the PA5 pin is pulled low during the boot-up
of the module, the module will also enter the bootloader, so exercise caution when doing hardware
design and ensure that this pin is not grounded during start-up and reset. If unused the pad can
be left floating and a pull-up is not required.
1.8.3 Compatibility with other devices
Most features of the R3xx Telegesis AT-Command line Interpreter are part of a Manufacturer
Specific Profile using the ZigBee PRO feature set of ZigBee 2007. Interoperability with other
devices that use the ZigBee PRO featureset is limited to a number of transparent commands.
R3xx is not compatible with earlier versions of ZigBee which do not implement the ZigBee PRO
featureset, including Telegesis R2xx firmware. Also, it is not compatible with the ZigBee Smart
Energy profile as it lacks the required security key.
1.8.4 Persistence of network parameters
Once a device has joined a network as a coordinator, router or end device, it will retain its network
parameters if it is powered off and on again. It will still be a member of its original PAN, assuming
that PAN still exists, though an end device may need to find a new parent and it may have missed
an update of the network key. Certain S-registers will have been reset to default values, though,
which may change an end device’s power mode for example.
