txcwdata | array of random data, which is permanently sent out. It is recommended, that the array has a length of 127, which is the maximum possible framesize, which can be stored in the SRAM of the radio transceiver. If the synchronisation header (SHR: 0,0,0,0,0xA7 ) is included in this array, and PRBS mode is selected, the continuous transmission can be recognized as a loop of individual 802.15.4-2003 frames without interframe spacing. | |
txcwmode | Select the mode of the continuous tranmission
