Bluetooth Alternative?

[ManuelBoe]

My son has a sealed PineTime watch with PineTime version 1.5 software installed. He wants to upgrade the software, but we can no longer connect to the watch with Siglo. I suspect that the bluetooth is no longer working.

So I can connect to another PineTime watch on the same computer, but not this watch. I don't believe there is any other way to connect, for example using the USB charge adapter to connect to the laptop USB port doesn't seem to be a viable way to communicate with the watch.

If the bluetooth stops working, is there any practical way to save this watch? It is set to 1970, and my son has installed a version of the software (1.5) that doesn't appear to support updating the time.

He has autism and is love with the PineTime watch. He spends endless hours upgrading and downgrading the software on it, because he wants to experience every version number. I guess the watch has been loved to death.

Any advice is apprciated.

Sometimes there are problems with bluetooth connections. Have you tried pairing the Watch on another computer?

There is also a new app "Watchmate" that is supposed to work better than siglo.



If bluetooth really doesn't work anymore, it is more difficult.

The usb cable that comes with the watch cannot be used to reflash infinitime. 

You need a special ST-Link V2 programmer, which you can buy for example at amazon.

To access the pins, the watch must be opened. This is not without danger and may break the watch.

This is only a rough description of the procedure! Proceed at your own risk!!!!

1. You can heat the adhesive on the Watch with a hairdryer or another warm object. Then you can quickly prise the Watch open with a screwdriver.

2. Wire the ST-Link V2 programmer to the pinetime as described in the following article:

3. Flash the new firmware as described in the following article:

The watch will then no longer be waterproof and you will have to find a way to reseal it.
