5.2 Packet RX TX

To enable the continuous packet transmission/receive the following command needs to be sent after the loading of the service pack:

HCI_VS_DRPb_Tester_Packet_TX_RX 0xFD85, 0x03, 0, 0xFF, 0, 2, 0, 27, 15, 1, 0x01FF

The parameters for the HCI_VS_DRPb_Tester_Packet_TX_RX can be found.

Note: By default, the device uses all the 79 channels in frequency hopping mode. To reduce the number of channels, the following commands should be executed prior to HCI_VS_DRPb_Tester_Packet_TX_RX.

  • Enable Local AFH Assessment

    HCI_Write_AFH_Channel_Assessment_Mode 0x1

  • Classify Channels to Reduce Hopping Scheme

    Bad Channel = 1, Unknown Channel = 0
<ChannelMap> = B0B1B2B3B4B5B6B7B8B9
Bx = b7b6b5b4b3b2b1b0
Chx = bx
Freq = 2402 + Chx
e.g. <ChannelMap> = '000000E0FFFF01000000', Blocked Channels = 0 - 28 and 49 - 78, Used Frequencies = 2,431MHz - 2,450MHz
