I made a post a while ago about this issue but I didn’t follow up on it. I replied to the old post and it has not received any attention, so I am creating a new post. Sorry for the duplicate! I was asked to send the unit back for repair and below is my follow up reply.
I went to the post office today and it was almost $60.00 US to ship it back to you. Before I do that can you give me a couple troubleshooting idea’s? Like I said earlier, this thing used to work perfectly, I let it sit for a while and plugged it and it was dead. My immediate thought is the battery is dead, but checking it with a multimeter, it registers 4.9V. When I plug in the USB cable there is a light that turns on on the main board. Also, I have not made any modifications to the software, it is 100% what you sent me initially.
When I connect the USB cable, I can see that a new Com port is assigned, are there any commands I can issue via a serial terminal to at least check the wheel motors to see if they are working? Since the screen is blank, is there a combination of directional key presses I can make to test the motors?
Are there any key points where I can check voltages to possibly identify a trouble area?
Now that I have byteboy, I am dedicated to get this working so that I can use them together. If I have t osend this back, I will but I am trying to avoid the $60.00 shipping cost.
