The Telegesis ETRX1 has been designed to be built into any device and
provide a low cost, low power, ZigBee™ ready meshing solution, using the
proven EmberNet technology. No RF experience or expertise is required
to add this powerful wireless networking capability to your products. The
ETRX1 offers fast integration opportunities and the shortest possible time
to market for your product. The AT style command line interface allows
the adopter to quickly integrate meshing radio technology into any product
without the need for complex programming or RF design work.
Example AT-Style Commands
• AT+SN Search network & discover
devices
• AT+BCAST Sends a Broadcast
• AT+UCAST:<address> Sends a Unicast
• AT+ASS:<address> Associate Node
At Power-up the last configuration is loaded from EEPROM.
This can eliminate the need for an additional Host
Controller.
