RN-XV-EK-DSPHYSICAL DIMENSIONS Figure 2 shows the evaluation board’s physical dimensions. DESIGN CONCERNS The fol owing sections provide information on designing with the RN-XV-EK module. Powering the Module When plugged in, the module receives power from the PC via the USB cable. GPIO9 Functions The AP pushbutton is connected to GPIO9. Depending on the state of GPIO9, the module goes into three different modes: access point (AP) mode, factory reset, and WPS mode. To put the module into AP mode, GPIO9 must be high when the module powers up or wakes from a sleep state. Press the AP mode button to drive GPIO9 high, and then press the reset button to reset the module. The module is in default AP mode, which creates a default access point network with the default parameters shown in Table 1. NOTE: This default mode overwrites any software settings. !
