1.4.1 BER Test - Between Two WiLink Devices

Note: Observe maximum RF input power during PLT test (-5dBm for BR and -10dBm for EDR)

The BER meter test can be performed using two Wilink_X devices. One of the devices will be classified as the TX board, and the other as the RX board.

Step 1:

Run the INIT script on each board.

Note: You can have two instances of HCITester running, as long as the COM ports are configured correctly.

Step 2:

Start the BER function on the RX board using the following script example:

$l10
count = 0

#DH5, 339 packet size x 8 bits x 590 packets = 1.6Mbits
#BD address = that of the TX board
Send_HCI_VS_DRPb_BER_Meter_Start 0xFD8B, 0, 0, 0x222222222222, 1, 0x5, 339, 590, 0x1FF, 0x1
Wait_HCI_Command_Complete_VS_DRPb_BER_Meter_Start_Event 5000, any, HCI_VS_DRPb_BER_Meter_Start, 0x00

#
$l11
Sleep 100
count++

Send_HCI_VS_DRP_Read_BER_Meter_Status 0xFD5B
Wait_HCI_Command_Complete_VS_DRP_Read_BER_Meter_Status_Event 5000, any, HCI_VS_DRP_Read_BER_Meter_Status, 0x00, &synched, &finished, any, &total_bits, &bit_errors, &packets
if finished== 0 then
	if synched == 0 then
		log"not synced yet %d count",count
		#Fail "no SYNC"
	else
		log"not finished yet %d packets, coutn %d",packets,count
	endif
	goto $l11
else
	BER = 1000000*bit_errors/total_bits
	log"BER is %d e-6 (%d bits out of %d)",1000000*bit_errors/total_bits,bit_errors,total_bits
	if BER > 100 then
		Fail "BER is too high"
	else
		pause "Finished"
	endif
	
endif

#pause""
goto $l10

Step 3:

The BD addresses between the TX and RX boards need to match in order for the BER Meter to function. Set the BD_ADDR on the TX board using the following command:

BD_ADDR="222222222222"
Send_HCI_VS_Write_BD_ADDR 0xFC06, BD_ADDR
Wait_HCI_Command_Complete_VS_Write_BD_ADDR_Event 5000, any, HCI_VS_Write_BD_ADDR, 0x00

Step 4:

Send TX packets with the TX board using the following commands:

Send_HCI_VS_DRPb_Enable_RF_Calibration_Enhanced 0xFDFB, 1, 0xFF, 0x00000000, 0x01
Wait_HCI_Command_Complete_VS_DRPb_Enable_RF_Calibration_Enhanced_Event 5000, any, HCI_VS_DRPb_Enable_RF_Calibration_Enhanced, 0x00
sleep 1000

# Sent Tx Packets
Send_HCI_VS_DRPb_Tester_Packet_TX_RX 0xFDCC, 0x5, 3, 2402, 0xFFFF, 5, 0, 339, 5, 1, 0x01FF
Wait_HCI_Command_Complete_VS_DRPb_Tester_Packet_TX_RX_Event 5000, any, HCI_VS_DRPb_Tester_Packet_TX_RX,
