$20 of beer money via PayPal or Square Cash to whomever helps me solve this problem that has been plaguing me for the past week. I am also willing to donate it to a charity of your choosing.
got my Sabvoton MQCON 960150 playing nice with my CA3-DP and Cromotor V3. It took hours, days (actually, 50 hours, I counted) to get it working. The biggest slap to the face, it’s in reverse with an abysmal current limit. Unrideable. Now I just have one more, rather blazing hurdle to hop over –
I cannot for the life of me get my PC to connect to this Sabvoton. The TX light just blinks away, seemingly mocking my futile efforts.
Here’s what I’ve tried:
1) Purchased an HC-05 module
(what Sabvoton uses as their “Bluetooth dongle”). Chopped female USB out from controller to reveal four wires (5V, GND, TX, RX). I set the baudrate to 19600
19200 and hooked it up to the TX and RX. No response via my Bluetooth COM. TX light just blinks away.
2) Purchased a USB to Serial TTL cable
. In same manner, directly hooked it up to Sabvoton’s exposed serial wires. No response. Same result.
1) I noticed that the GND wire for the serial isn’t actually grounded. It shows up as 0L on my multimeter. So I took my bench power supply and powered/grounded 5V into the HC-05, bypassing the output of the Sabvoton minus the RX and TX. Now that I realize it, this may have been ineffective due to the fact serial uses the ground as a variable while transferring data.
2) I did not hook up the red 5V from the USB adapter as I did not want to blow up the Sabvoton’s internals. I was not able to observe anything over my serial monitor.
What the hell do I do?! Do I really have to order one of those cables from China with $20 shipping? Why can I simply not get this to work?
Relevant information, etc –
Windows 7 PC.
Tried using drivers included with controller but it was for an entirely different chip.
Tried different baudrates. Different COM ports.
Tried swapping RX/TX.
