EZBee series Manual / Ver. 1.0 61. 1. 1. 1. Products Overview Products Overview Products Overview Products Overview EZBeeTM formats include OEM modules (M100), industrial serial adapters (S100), USB type serial adapters (U100), and internet access points (L100) for supporting various customers who need to get wireless solutions in industrial automation, medical automation, building automation, information technology, retail/ POS and so on. The EZBeeTM series is a 2.4GHz ISM band transceiver, based on the Chipcon CC2420 chip for IEEE 802.15.4. The EZBeeTM series supports various AT- style command line interfaces for allowing customers to quickly build mesh networks requiring lower power consumption without skillful wireless RF engineering and complex software engineering. It also provides 2 ADC ports and 8 I/ O ports for enabling customers to conveniently design own embedding systems. The EZBeeTM series implements three different data transmission modes including ASCII, Bypass and EBI (EZBee Binary Interface) mode. In ASCII mode, all data are transmitted as format of ASCII HEX by utilizing the AT command sets for data transmission. In Bypass mode, all raw data are transmitted to the pre- assigned EZBee module without utilizing any specific commands or building any communication packet, as if EZBee modules are wired together. In EBI mode, the transmitting data packets can be configured by

However, the extended address is difficult to use due to its big size. The short- address is mostly used in real practical communication. Because the short- address is assigned dynamically by a coordinator when a modem is joined in PAN, users can not know the short- address before joining in PAN. Followings are the AT commands for setting a new modem ID or checking the modem ID assigned. Command Parameter Result Description AT+ID?

If a sender is set as Bypass mode and a receiver as ASCII mode, and the sender sends a long message, the receiver can receive the message as divided length of messages due to the size of internal buffer or transmission delay. For converting from the Bypass to ASCII mode, a string “ +++” should be typed at least 300 [ msec] later after transmitting the final data. A mode converting is succeeded if no characters are inputted during 300 [ msec] after inputting the string “ +++” .

If failed, non- zero value is shown as <Result>. Accordingly, the message is transmitted successfully; a following event message related to the message arrival is displayed in a router terminal. The format of an event message related to the message arrival is, ““““$MSG@$MSG@$MSG@$MSG@<SrcID>,,,,<SrcSaddr>,,,,<LinkQuality>====<Msg>””””
EZBee series Manual / Ver. 1.0 58 where, <SrcID> is a sender ID, <SrcSaddr> is a short- address of sender, <LinkQuality> means a receiving sensitivity, and <Msg> means the received message having same ASCII Hexadecimal format as sending message In this example, <SrcID> is 0000, and it means a sender is a coordinator. <SrcSaddr> is 0000000000000000. It shows that the short- address of the coordinator is always 0000. <LinkQuality> is 218218218218. The value of receiving sensitivity is between 0 and 255. Finally, <Msg> is 3030303030303030303030303030303030303030303030303030303030303030. It means 8 byte data string having value of 0x30. From now on, as a reverse transmission, a router terminal sends a data to a coordinator terminal. Using ““““ AT&MSG=AT&MSG=AT&MSG=AT&MSG=<DstID>,,,,<Msg> ””””, a router sends a message to a coordinator. In this case, <DstID> is set as 0 for a coordinator.
EZBee series Manual / Ver. 1.0 59 When the command is completed successfully, the event message related to the message arrival is shown on a coordinator terminal.

Testing Input/ output function of Testing Input/output function of Testing Input/output function of Testing Input/output function of EZBeeEZBeeEZBeeEZBee M100M100M100M100 EZBee M100 supports total 8 ports of GPIO from DIO0 through DIO7 which are set or controlled by a local or remote modem of EZBee. First, enter ““““AT+IOD?AT+IOD?AT+IOD?AT+IOD?”””” command on a coordinator terminal to check the I/ O directions of local EZBee M100. In this example, the return value shows ““““00000000””””, it means all I/ O ports are assigned as input ports.
EZBee series Manual / Ver. 1.0 61 Next, enter ““““AT+IO?AT+IO?AT+IO?AT+IO?”””” command in order to read the input value of a current I/ O ports. The return value is ““““BFBFBFBF””””, it is interpreted that DIO6 is 0000, the others are all 1111. During pushing DIO3 of a coordinator module, enter ““““ AT+IO?AT+IO?AT+IO?AT+IO?”””” on coordinator terminal again.
EZBee series Manual / Ver. 1.0 62 The return value is changed to ““““B7B7B7B7””””. It means the input of DIO3 is changed from 1 to 0. Now, enter ““““AT+IOD=FFAT+IOD=FFAT+IOD=FFAT+IOD=FF”””” command on a coordinator terminal. The GPIO I/ O direction is changed, thereby all ports acts as output ports. If command is completed successfully, the direction value of input/ output is displayed as shown in a figure.
EZBee series Manual / Ver. 1.0 63 In this moment, enter ““““AT+IO=00AT+IO=00AT+IO=00AT+IO=00”””” command again. You can see that DIO0 and DIO1 LED in the coordinator module are turning ON. Using similar philosophy, the GPIO of a remote modem is able to set and control.
EZBee series Manual / Ver. 1.0 64 Enter ““““ AT+IOD@1?AT+IOD@1?AT+IOD@1?AT+IOD@1? ”””” command on a coordinator and read GPIO input/ output status. When the command is completed successfully, the response message, ““““$IOD@1=00$IOD@1=00$IOD@1=00$IOD@1=00”””” is displayed, which means all GPIO of a router is set as inputs. To read GPIO input status value of a router module, enter ““““AT+IO@1?AT+IO@1?AT+IO@1?AT+IO@1?”””” on a coordinator terminal. If the command is completed successfully, the response message such as ““““$IO@1=BF$IO@1=BF$IO@1=BF$IO@1=BF”””” is outputted. It means the input value of DIO6 is 0 and the others of GPIO are 1.
EZBee series Manual / Ver. 1.0 65 Enter ““““AT+IO@1?AT+IO@1?AT+IO@1?AT+IO@1?”””” on a coordinator terminal while the button of DIO3 is pushed. When the command is completed successfully, ““““$IO@1=B7$IO@1=B7$IO@1=B7$IO@1=B7”””” message is outputted, and it means the input value of DIO3 is changed to 0.

Testing ADC of Testing ADC of Testing ADC of Testing ADC of EZBeeEZBeeEZBeeEZBee M100M100M100M100 EZBee- M100 provides 2 channel ADC having 10- bit resolution and is possible to read the ADC value of a local or remote modem. Enter ““““AT+ADC?AT+ADC?AT+ADC?AT+ADC?”””” command for reading ADC value of a coordinator module. When the command is completed successfully, the value of ““““<CH1>,,,,<CH2>” are displayed as shown in above figure. In this example, the channel values of ADC are 008B008B008B008B for <CH1> and 0000000000000000 for <CH2>. In similar manner, the ADC value of a remote modem is able to read. To read the ADC value of a router module, enter ““““ AT+ADC@1?AT+ADC@1?AT+ADC@1?AT+ADC@1? ”””” command on a coordinator terminal.
EZBee series Manual / Ver. 1.0 67 When the command is completed successfully, the result message such as ““““$ADC@$ADC@$ADC@$ADC@<SrcID>====<CH1>,,,,<CH2>”””” is displayed. In here, <SrcID> is a remote modem ID, <CH1> and <CH2> means the ADC channel value of each modem. In this example, <SrcID> is 1111, <CH1> and <CH2> are 0000000000000000 and 0000000000000000, respectively. ※ The usage of EZBee U100 and EZBee L100 is same as EZBee M100. ※ In data transmission process between EZBee formats, the transmitting data loss may be happened due to the characteristics of RF signal and environment of RF transmission.
