- ETRX351HR, ETRX357HR, ETRX351HR-LR, ETRX357HR-LR, ETRX351HR-LRS, ETRX357HR-LRS The Telegesis ZigBee modules have been designed to be built into any device and provide a low cost, low power ZigBee solution based on the industry leading EmberZNet ZigBee stack. Integration into a wide range of applications is made easy using a simple AT-style software interface and advanced hardware design.
(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.
1.4.3 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.
2.3.2 Non-ZigBee types Sink. The sink is a Telegesis feature. When a node is defined as a sink by setting S10 bit 4, it can broadcast its address to the rest of the network. Other nodes can then send messages to the sink node using AT+SCAST or various built-in functions.

In case the target already in the bootloader. device has been reset channel 13 must be used for recovering.

To factory reset a module, connect it to the PC‟s serial port and execute the Factory Reset Tool (downloadable from www.telegesis.com). When pressing the Reset button on the Reset Tool you are prompted to cause a hardware reset to the module by pulling the module‟s reset line low for more than 100ms (done by pressing the reset button on the...

Bit D: Set: Present 1.2V A/D-Reference at I/O0 Note during measurement (ETRX2 only) On the ETRX2 series IRQ0,1,2,3 are Bit C: Set: I/O8 turns into A/D3, which can be read generated by logic transitions on inputs from S21 (ETRX2 only)
If no means of waking up from any of the power down modes has been defined and the module appears unresponsive the Telegesis factory default resetter can be used to reset the modules factory defaults via the serial port.
On the EM250 as well as the EM35x, the LQI is closely related to the SNR (signal noise ratio). The graph below shows the relation between the SNR and the LQI reading on the EM250, which is the basis of the ETRX2 series of modules. EM250 SNR vs LQI Figure 1: LQI vs.
R305 AT Commands 9 Upgrading from R2xx to R305 on the ETRX2 Series R305 firmware can be loaded on to an ETRX2 by bootloading through the serial port or by re- flashing with an Ember Insight Adaptor. Cloning over the air is tricky because the new R305 node and the old R2xx node will not join the same PAN.
