ETRX358USB Reference Manual
Zigbee® & Thread Compatible Radio for IoT Applications in a
USB Stick Form Factor
The ETRX358USB is a USB device peripheral designed to enable USB host devices to
connect to the Internet of Things over 802.15.4 Networks. The in-field upgradeable
firmware allows interaction with either ZigBee or Thread wireless mesh networks.
Featuring the Telegesis™ ETRX3588 wireless mesh networking module (based on the
EM3588 System-on-Chip (SOC) from Silicon LabsInc.), the ETRX358USB takes advantage of a powerful 32-bit ARM® processor with 512 kB of flash memory and 64 kB
of RAM. A link budget of up to 110 dB is ideal for typical ZigBee and Thread applications.
The devices make use of the standard USB communication device class (CDC) allowing the best possible native driver support across a wide range of operating systems.

3. Transmit Power Characteristics
The diagrams below show the typical output power and current in dependency on power setting. Power settings above 3 dBm have
Boost Mode enabled. Note that the output power is independent of the supply voltage as the radio is supplied by an internally regulated
voltage.

Bootloading Firmware
5. Bootloading Firmware
Bootloading allows the user to change or upgrade the device firmware via USB serial using the XMODEM protocol.
If no application is present on the device, the device will automatically start into bootloader mode. If the device already contains an ATCommand style application firmware, the bootloader may be accessed using the AT+BLOAD command.
Once the device is powered, connect to the device using suitable terminal software such as HyperTerminal, PuTTy or Telegesis Terminal.
• Baud rate: 19,200 baud
• Parity: No
• Flow Control: No
• Data bits: 8
Sending a Carriage Return character (ASCII: 0x0D) will display the bootloader command prompt. The white LED will also be lit.
