23.6.4.8 PHY Test Transmit Command
The test packet transmitter command may be used to transmit physical layer test packets.
A test packet transmitter operation is started by a CMD_BLE_TX_TEST command. In the command
structure, it has a pParams parameter of the type defined in
type defined in Table
then programs the frequency based on the channel parameter of the command structure. The radio CPU
sets up the test mode packet access address and uses the CRC initialization value 0x55 5555. The
whitener is set up as defined in the whitening parameter. To produce PHY test packets conforming to the
BLE Test Specification, the whitener must be disabled.
The radio CPU transmits pParams->numPackets packets, then ends the operation. If pParams-
>numPackets is 0, transmission continues until the operation ends for another reason (timeout, stop, or
abort command). The time (number of radio timer ticks) between the start of each packet is given by
pParams->period. If this time is smaller than the duration of a packet, each packet is transmitted as soon
as possible. Each packet is assembled as follows by the radio CPU. The first byte is a header byte,
containing the value of pParams ->packetType, provided this one of the values listed in
next byte is the length byte, which is the value of pParams->payloadLength, and followed by a number of
payload bytes which are as listed in
>payloadLength. If pParams->packetType is 0, the bytes are from the PRBS9 sequence. Otherwise, all
the bytes are the same, as listed in
appended.
