Powering On and Off the TTGO T Beam V1.x
The newer TTGO T-beam units have a power push button instead of a switch. This makes a configurable switch that needs some understanding.
For powering on the unit you need to “Short Press” the power button (one or two secs).
On our printed 3d housing the power button is a small tab just to the right of the charging usb port, that if you press you will feel it “clicks” the power button on the board. It's a little hard to press but it's intentional, so it will be difficult to power on while stow on the harness during your ride to takeoff.
Next to the power button tab, there is a small hole for accessing the “soft reset” button, if the device gets locked or “software frozen” and you don't want to open the case to remove the battery.
For powering off the unit you need to “Long Press” the power button. This is tricky, as it´s takes about 8 seconds. On the TTGO V1.1. with OLED when you power off the device, it shows a “power off sequence” on the screen and then it turns off the screen. Keep pushing the button at least 4 secs after the screen is off.
If you fail to do so, you will see that even when the screen is off and the device stops working, there is a tiny red led behind the Oled Screen (on our printed 3d case you can see it through the charge port hole behind the screen). This means that the device is on “stand by” and we are guessing that it will drain the battery at a really slow rate.

Device turned on, if you see blue and red light (not visible on pic because blue intensity) |
If you see a red light, then you did not push long enough and the device is on “stand by” and not fully off. |
