Testing Input/ output function of EZBee M100 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?” command on a coordinator terminal to check the I/ O directions of local EZBee M100. In this example, the return value shows “00” 00”, it means all I/ O ports are assigned as input ports. EZBee series Manual / Ver. 1.0 60 Next, enter “AT+IO?” AT+IO?” command in order to read the input value of a current I/ O ports. The return value is “BF” BF”, it is interpreted that DIO6 is 0, the others are all 1. During pushing DIO3 of a coordinator module, enter “ AT+IO?” AT+IO? ” on coordinator terminal again. EZBee series Manual / Ver. 1.0 61 The return value is changed to “B7” B7”. It means the input of DIO3 is changed from 1 to 0. Now, enter “ AT+IOD=FF” AT+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 62 In this moment, enter “AT+IO=00” AT+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 63 Enter “ 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” $IOD@1=00 ” is displayed, which means all GPIO of a router is set as inputs. To read GPIO input status value of a router module, enter “AT+IO@1?” AT+IO@1?” on a coordinator terminal. If the command is completed successfully, the response message such as “$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 64 Enter “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 ” message is outputted, and it means the input value of DIO3 is changed to 0. EZBee series Manual / Ver. 1.0 65 7. Testing ADC of EZBee M100 EZBee- M100 provides 2 channel ADC having 10- bit resolution and is possible to read the ADC value of a local or remote modem.
