XBee Tutorial

Before starting this XBee Tutorial 6 (XBee T6), the basic knowledges in T1 - T5 should be all studied. Without those information, user will just get puzzled and confused with the parameters for Zigbee network configuration. Since XBee shares the same pins (Tx/Rx) for configuration and data sending, so it defines 2 modes for distinguish them: Transparent Mode (Sending data wirelessly, the data it got will be sent) Command Mode (Parameters update/configuration, use AT command) Transparent Mode The default mode of XBee for sending/receiving data wirelessly The data from serial Rx pin, will be sent out wirelessly The data from air (antenna), will be sent to serial Tx pin Command Mode The mode for network parameters configuration 1 sec silence + " +++ " + 1 sec silence After 10 sec without any input (10 sec silence), the command mode will be quit and back to Transparent Mode The command mode can be quit with command "ATCN" API Mode Transparent mode is for basic wireles

There are 2 types of XBee Grove Development Board, one is THT (Through-Hole Technology), the other is SMT (Surface-Mount Technology). For the THT type, the XBee can be plugged in to the development board easily. For the SMT one, it needs to do the soldering work. XBee THT Grove Development Board Totally 20 pins, 10 for each side XBee SMT Grove Development Board Totally 34 pins, 1 3 for L/R side , plus 8 on bottom 1. Connect through VCP For XBee THT type, check the pin definition table below. The Development Board comes with a FTDI chip which allows user be able to connect XBee to a PC/Laptop with a USB cable. Then the XBee can be configured / updated firmware through Digi X-CTU software easily. 2. Connect through RS232 With the pin definition table, user can also use a bread board to do the configuration and firmware update. After power on the XBee with pin1 & pin10, PC/Laptop can communicate to XBee with serial TX/RX pin easily. For update the XBee parameters, using TX/RX pin

Before check this XBee comparison table, the basic knowledges on XBee T1, XBee T 2 , and XBee T 3 should be studied. There are 3 Digi xbee models listed here, Zigbee 3, 802.15.4, and DigiMesh 2.4. Consumers can select the right one base on application situation. Such as, if there are other wireless devices in the network using Zigbee protocol, then Digi XBee 3 Zigbee 3 RF Module should be used. If there is no other wireless devices and the case needs a mesh type network, then Digi XBee 3 DigiMesh 2.4 RF Module may be a good choose. If the ca se just needs a simple peer to peer / star t ype network, the Digi XBee 3 802.15.4 RF Module will be the best pick up. . Some notes about the spec listed on the table: Sleep Current: The lower the better, since there is less current leakage and this makes the battery can last longer. 1.7 uA is a very very low leakage current. Receive Sensitivity: The transmit power will decay with distance. The minimum power level at which the receiving node i
