These documents will be available from our website or on request 2.5 IEEE 802.15.4 IEEE 802.15.4 is a standard for low data rate, wireless networks (raw bit-rate within a radio packet of 250kbps @2.4GHz) which focuses on low cost, low duty cycle, long primary battery life applications as well as mains-powered applications. It is the basis for the open ZigBee Protocol.
ETRX358x-LRS and ETRX358x-LRS ©2014 Telegesis (UK) Ltd - 11 - ETRX358x-LRS Product Manual 2.6 The ZigBee Protocol The ZigBee Protocol is a set of standards for wireless connectivity for use between any devices over short to medium distances. The specification was originally ratified in December 2004, paving the way for companies to start making low-power networks a reality. ZigBee uses an IEEE 802.15.4 radio specification running on the 2.4GHz band, plus three additional layers for networking, security and applications. What makes the specification unique is its use of a mesh network architecture which, in bucket chain style, passes data from one node to the next until it lands at its destination. The network is self-healing and adapts its routing as link quality changes or nodes move. Furthermore, nodes can be defined as End Devices which do not act as routers, but can therefore be put into a low-power sleep state. The enhanced version of the ZigBee standard (or ZigBee 2006) was released in December 2006, adding new features and improvements to the only global wireless communication standard enabling the development of easily deployable low-cost, low-power, monitoring and control products for homes, commercial buildings and industrial plant monitoring. In 2007 the ZigBee Alliance introduced the PRO feature-set which offers advantages over earlier feature-sets, including • Truly self-healing mesh networking • Messages can now travel up to 30 hops • Source-Routing for improved point to multipoint message transmission • Improved security including Trust-Centre link keys • New message types and options The Telegesis AT Command-set, which by default ships on all ETRX3 series products is based on the ZigBee PRO feature-set. For more information on the Telegesis AT Command-set please refer to the separate documentation at www.telegesis.com.

Hardware Diagram The ETRX358x-LRS and ETRX358x-LRS are based on the Silicon Labs EM358x family of ZigBee SoCs in addition to a frontend module containing a PA, LNA and RF switch in addition to the RF-frontend circuitry. The EM358x family of ZigBee SoCs are fully integrated 2.4GHz ZigBee transceivers with a 32-bit ARM® Cortex M3TM microprocessor, flash and RAM memory, and peripherals. The industry standard serial wire and JTAG programming and debugging interfaces together with the standard ARM system debug components help to streamline any custom software development. In addition to this a number of MAC functions are also implemented in hardware to help maintain the strict timing requirements imposed by the ZigBee and IEEE802.15.4 standards. The new advanced power management features allow faster wakeup from sleep and new power-down modes allow this 3rd generation module to offer a longer battery life than any 2nd generation modules on the market. The EM358x has fully integrated voltage regulators for both required 1.8V and 1.25V supply voltages. The voltages are monitored (brown-out detection) and the built in power-on-reset circuit eliminates the need for any external monitoring circuitry. A 32.768kHz watch crystal can be connected externally to pads 3 and 4 in case more accurate timing is required. 4.1 Hardware Interface All GPIO pins of the EM358x chips are accessible on the module’s pads. Whether signals are used as general purpose I/Os, or assigned to a peripheral function like ADC is set by the firmware. When using the Telegesis AT Commandset please refer to the AT Commandset manual and the development kit manual for this information and when developing custom firmware please refer to the EM358x datasheet [2].
ETRX358x-LRS and ETRX358x-LRS ©2014 Telegesis (UK) Ltd - 15 - ETRX358x-LRS Product Manual 5 Firmware Description By default, the modules will be pre-loaded with a standalone bootloader which supports over-the-air bootloading as well as serial bootloading of new firmware. In order to enter the standalone bootloader using a hardware trigger pull PA5 to ground and power-cycle or reset the module. To avoid entering the standalone bootloader unintentionally make sure not to pull this pin down during boot-up unless the resistance to ground is >10kΩ. (A pull-up is not required). In addition to the standalone bootloader the modules also contain the current release of the Telegesis AT-style command interface as described in the Telegesis AT command dictionary and the Telegesis user guide. Check www.telegesis.com for updates. Each module comes with a unique 64-bit 802.15.4 identifier which is stored in non-volatile memory. The commands and responses pass through the serial port of the ETRX358x as ASCII text, so a simple terminal application will usually suffice. We provide Telegesis Terminal for interaction with the module but it is not an essential feature. The pre-loaded AT-style command interface firmware is based on the EmberZNet PRO meshing stack which implements routers/coordinators as well as (sleepy) end devices. [End devices have no routing responsibility and therefore are allowed to go to sleep, whilst still being able to send and receive messages via a parent router. In addition to classical sleepy and non-sleepy end devices the module firmware also supports mobile (sleepy) end devices capable of changing their parent quickly whenever they change their position within the network.] A router is typically a mains powered device whilst a sleepy end device (SED) can be battery powered. The module is also able to act as a coordinator and Trust Centre through external host control. The AT style command line supplies all the tools required to set up and manage a ZigBee network by allowing easy access to the low-level functionality of the stack. The Telegesis firmware uses the meshing and self-healing EmberZNet PRO stack to overcome many of the limitations of the tree network topology of the ZigBee 2006 stack by using the ZigBee PRO featureset. The Telegesis firmware allows low-level access to physical parameters such as channel and power level. Parameters that define the functionality of the ETRX358x module and also allow standalone functionality are saved in non-volatile memory organised in so-called S-Registers. The SPI and I2C buses are not supported by the current firmware release, but can be used with custom firmware.

Manufacturing tokens 5.2 Custom Firmware For high volume customers the firmware can be customised on request. In addition to this the ETRX358x-LRS series of modules is an ideal platform for developing custom firmware. In order to develop custom firmware the Silicon Labs Ember toolchain is required. When writing firmware for the ETRX358x-LRS it is important to ensure that pins PB0 and PC5 are correctly configured in order that the RF front-end module can operate correctly. An application note “Writing customised firmware for the ETRX35x-LRS” can be downloaded from the Telegesis website. 5.3 Boost Mode vs. Normal Mode The Ember EM358x chips support a “boost mode” power setting next to the “normal mode” power setting. The “boost mode” setting increases the sensitivity and output power of the radio transceiver, however with the LRS variants enabling boost mode has no positive effect on neither the output power nor the sensitivity and therefore it is recommended to not use boost mode on this platform. The Telegesis AT Command-set firmware automatically disables boost mode on LRS series modules and adjusts the power maximum power settings. Section 10.2 lists the requirements for the maximum power settings for use of the LRS family in different countries.

Unless using the “HR” variants the “keep-out” zone shown in section 11 must be retained, and it must be ensured that this area is free of copper tracks and/or copper planes/layers. You must also ensure that there is no exposed copper on your layout which may contact with the underside of the ETRX3 series module. For best RF performance it is required to provide good ground connections to the ground pads of the module. It is recommended to use multiple vias between each ground pad and a solid ground plane to minimize inductivity in the ground path. Figure 10. Recommended Footprint The land pattern dimensions above serve as a guideline. We recommend that you use the same pad dimensions for the solder paste screen as you have for the copper pads. However these sizes and shapes may need to be varied depending on your soldering processes and your individual production standards. We recommend a paste screen thickness of 120µm to 150µm. Figure 11 shows the typical pad dimensions of the module and Figure 12-Figure 14 in section 14.1 show examples of how to align the module on its host PCB.
ETRX358x-LRS and ETRX358x-LRS ©2014 Telegesis (UK) Ltd - 31 - ETRX358x-LRS Product Manual Although the undersides of the ETRX3 series modules are fully coated, no exposed copper, such as through-hole vias, planes or tracks on your board component layer, should be located below the ETRX3 series module in order to avoid ‘shorts’. All ETRX3 series modules use a multilayer PCB containing an inner RF shielding ground plane, therefore there is no need to have an additional copper plane directly under the ETRX3 series module. Figure 11. Typical pad dimensions Finally it is recommended to use no clean flux when soldering the ETRX358x family of modules and to not use a washing process after reflow. If the process does require washing then care must be taken that no washing agent is trapped underneath the shielding can after the drying process has completed.

ETRX358x-LRS and ETRX358x-LRS ©2014 Telegesis (UK) Ltd - 34 - ETRX358x-LRS Product Manual 14.2 Example carrier board Since the RF performance of the module with the on board antenna is strongly dependent on the proper location of the module on its carrier board figure 17 shows the reference carrier board which was used during testing by Telegesis. Figure 17: Reference Board For best performance it is recommended to locate the antenna towards the corner of the carrier board and to respect the recommended keep-out areas as described in section 11. Finally to provide a good reference ground to the on board antenna, the carrier board should have a ground plane spanning no less than 40 x 40mm. In many cases a smaller ground plane will suffice, but a degradation in radio performance could be the result.
