for EMC test I need to put the BLE radio of the BYBLE-022001 in a particular test mode, i.e. contiguous transmit on a low/mid/high frequency channel at low/mid/high power and in contiguous receive mode. My PCB allows access to the serial interface via FTDI USB-UART. Is there any example program which allows me to switch between such modes, e.g. HCI or AT commands etc.
