Description of the Issue: DTM commands are not properly executed. The Bluetooth sniffer shows that the data packets do not contain the correct information (data length and payload) that is set to be transmitted through HCI commands. This also causes CRC errors during DTM.

Steps to reproduce the Issue: The sample code can be seen below. The same code was successfully used on old SDK versions.

uint8 txChan = 11;
uint8 payloadLen = 15;
uint8 payloadType = HCI_DIRECT_TEST_PAYLOAD_0x0F;
uint8 txPhy = HCI_PHY_1_MBPS;
HCI_LE_EnhancedTxTestCmd(txChan,payloadLen, payloadType, txPhy);
//Wait a few seconds
HCI_LE_TestEndCmd();
