Controller issues

[alexswerner]

Something seems to be wrong with our gamepad controller. When I first too it out of the box and started charging it, it turned amber which seemed fine. However after some time I disconnected it and it stayed amber. Even pressing the pairing key combo, nothing changed. Only the reset button on the back helped.

Now connecting often fails, as does driving the robot. We are still investigating if this is an issue with this particular controller or with the raspi bluetooth module.

It could well be that the controller is just not charged. When I connected to USB for charging today evening, it did not light up at all. Different cables/different USB outlets did not affect the behavior.

Can you try the following:

• SSH into the RPI and call sudo bluetoothctl --agent=NoInputNoOutput
• In the CLI type devices. This should show the MAC of the paired controller
• Type in remove <MAC> to remove the controller. Also type untrust <MAC> to untrust it.
• Follow the controller setup instructions to re-pair.

Thanks! I'll try that tomorrow.

Since there was no signal of life (LED was always off) from the controller, I decided to investigate it. After opening it, the battery turned out to be at 4.16V. Unplugging the battery for 3 seconds brought the controller back to life. Tried before to get that by pressing the reset button, but that again did not work. Probably a power management issue with that controller.

I will further investigate the connection stability and ability to control the robot.

Quite frequently, the controller does not pair with the robot. Even when holding it right next to the robot.

Same with my controller. It was not showing any sign of life. The reset button saved its life.

I've encountered difficulties too:
I couldn't connect after I've paired successfully. The PI stated it was connected but the controller was blinking still.
I just tried trust and then connect without the pair, which worked for me.

EDIT: it worked for a second, the controller turns off 10 seconds later automatically. So basically not working. Can't get it to pair and connect.

Closing as stale.
