How to Fix OBDSTAR P001 Purple LED Error?

 Problem:

I tried to read eeprom 24C64 with obdstar x300 dp plus. After connect P001 adapter with x300dp, the LED indicators turns purple instead blue and failed to read.

It works before. Since Obdstar’s last update, the adapter is no longer working. I cannot use it to precode keys and cards.
The led should be blue when it works correctly.

Solution:

For those who have this problem.
We need to force the reset of P001. Problem solved.

The OBDSTAR P001 should be plugged into the obdstar tablet that is off and not powered in 12 volt.

Then plug the 12 volt power supply to obdstar tablet wire x300 DP plus.  (LED on corner of screen must turn on)

The tablet needs to turn on and the P001 will reset at the same time as the tablet starts..

If everything goes well, the P001, will reset in blue and you can use it again.

Now the P001 works perfectly.  Blue light.
