LXinput.txt - test input sent to BT-20
EchoCOM.exe - to echo any input
LXtest.exe - to send test input and log the reply to LXoutput.txt


The test described below was made using two PCs at a distance of 3m.
The test can also be done using a single PC.
The results show:
1) original StarLink protoype with blue LED is working.
2) StarLink product (100 units) have slow response and data transmission errors!

Summary:
BT-20 must respond quickly and with no data transmission errors.
Current StarLink product is not useable.



These tests #1 and #2 were done as follows:
FIRST:
1) install RS-USB driver from www.stargps.ca/pub/pl2303.zip
2) plug RS-USB adapter cable into a PC
3) use Device Manager to confirm RS232-USB Serial Comm (say COM2)
4) attach BT-20 to RS-USB cable (LED should turn on, blinking)
5) run EchoCOM.exe and select COM2
4) click on the "Connect" button
6) now any data sent to StarLink will be echoed back
SECOND:
7) use Bluetooth-USB adapter, establish a Bluetooth connection to BT-20
8) suppose BT-20 is assigned virtual COM6
9) run LXtest.exe and select COM6
10) click on the "Run tests..." button
11) this will write each line in the LXinput.txt file to COM6
12) a "#" character is appended to each line to mark the end
13) the results that are read back are displayed along with the time in milliseconds
14) the results are logged to LXoutput.txt
15) the test is repeated using both BT-20 samples

For example:
1) the line "123" would be written as "123#" to COM6
2) the BT-20 would receive "123#"
3) EchoCOM.exe receives "123#" and echoes it to the BT-20
4) the BT-20 would send "123#"
5) LXtest.exe will read the result, something like "<76>123#"
In this example the <76> indicates there was a delay of 76 milliseconds
after writing (step 1) until reading (step 5)
