The EVK provides the power supply for Antenna power. Use the BIAS switch to select the power source. INT_BIAS with recommended maximum output current 20 mA is powered by the module, and EXT_BIAS with recommended maximum output current 50 mA is powered by the LDO. 2.2 Reset(PRRSTX) button Press the reset button to generate a hardware reset to the module. 2.3 Boot(PRTRG) button The boot button is used to set the module to enter BootROM command mode. In this mode the module executes only the minimal functionality, such as updating new firmware. Follow these steps to enter BootROM command mode:  Press and hold the BOOT button first, and then press RESET button.
