Gemini PDA - Android / Cover LED flashing purple since OTA update? What does it mean?

« on: June 22, 2018, 07:44:24 pm »

Ah! the LED indicator that flashes purple when wifi is on, wifi is on but not connected, and wifi is off!

Wonderful!

Perhaps flashing purple means "This device supports wifi"??!?!

However, what do you know! I just enabled flight mode and the led went off.. I disabled flight mode and it stayed off?!!

Very odd! So, if there's a flashing purple led that won't quit, try turning flight mode on then off!

I installed the recent OTA update on my X27 Gemini and now an LED at the left end of the cover is continuously flashing purple (well, red and blue)

I have no idea what it means or how to stop it.

Connecting/removing charger lights other LEDs. Receiving notifications (like an email for example) makes a red LED light flash on the right hand side.

If I leave my gemini alone for some time, the flashing stops and the LED remains on constantly. I open the gemini and it starts flashing again?!

Has anyone any definitive list of what these flashing lights mean?

Just to add, although its a 4G X27 model, I do not have a sim installed at the moment

According to the Gemini Quick Start Guide that LED is a Wireless indicator LED.

Gemini PDA - Hardware / Puzzled about USB configuration

« on: June 06, 2018, 10:52:19 am »

It's more complex and possibly more buggy than this.

Here's what experimentation has shown so far:

With the Gemini powered on:

• A regular USB-C charger is not detected
• A charger connected via the USB-C hub is not detected

However, if you power the Gemini off:

• Attaching a regular USB-C charger will start charging
• Attaching the hub and a charger will start charging
• Powering on the Gemini will boot and continue to charge
• Disconnecting the charger (or hub) and re-attaching will not resume charging
• When powered on, it only recognises USB-A chargers (using a USB-A -> USB-C cable) such as the charger that comes with the Gemini

Since it works if booted when attached, it feels like a firmware update would correct this behaviour and allow powered hubs and proper USB-C chargers. At the moment it requires a power off/on to use power alternatives which is a huge shame.

yes, but USB C PD is required to hub+charge and the gemini doesn't support USB PD. I have all but confirmed this with multiple USB C PD chargers (gemini won't charge at all from them) and the gemini hub plus a 3rd party hub each with a variety of PD and non-PD chargers.

The gemini will ONLY charge (no hub) via non-PD chargers. Thus, no PD support. Thus, no HUB+charge under any circumstance I can think of.

If I turn off my Gemini, plug in the hub, plug my apple charger into the hub, the gemini starts charging.

If I power on the gemini, it continues to charge.

If I unplug the hub or the charger and re-attach, it does not resume charging..

I've not found any mention of it here, but...

If I plug my Gemini in whilst it is powered OFF, it will charge with every usb-C charger I have (off the top of my head):

• Apple 29W USB-C
• LG Nexus 5X USB-C charger
• TeckNet 27W USB-C + Dual USB-A

If I leave it plugged in and power on, it still charges.

If I disconnect the charger and re-connect whilst powered on, however, it doesn't see the charger again. I must power off first.

So, if it works when powered off, surely its a firmware update to make this work more reliably?

It can't be a valid hardware limitation: "You must turn the device off to charge"?

Just to be clear, if I use the USB-A to USB-C cable and a USB-A charger, the device will charge normally without the need to power off. Its only with a USB-C to USB-C cable and a standard USB-C charger that this cumbersome step is required?!

Maybe it's the same with the hub connected? Could someone with the Gemini and hub try? Then it might be possible to charge the Gemini while using the hub with a software update??
