GPS backup power for warmstart #115

Closed dodo124 closed 3 months ago

dodo124 commented 7 months ago

Hello and good morning,

I'm confronted with a new behaviour of my TTGO t-beam V1.1.

For the last couple of years it has worked perfectly as a TN mapper device.

But lately it cannot perform a warm start.

When I turn it off at 8pm and turn it on again at 6am, it has lost all GPS information.

The small battery next to the GPS module is almost empty and does not seem to be charged.

So should I do a factory reset or what else can I do?

Regards, Dom

You can try to use this example, the results will be output in the Serial monitor. Please try https://github.com/Xinyuan-LilyGO/LilyGo-LoRa-Series/blob/master/examples/GPS/UBlox_Recovery/UBlox_Recovery.ino

html,body{background-color:#fff;color:#333;line-height:1.4;font-family:sans-serif,Arial,Verdana,Trebuchet MS;}Hi Lewis, I followed the instructions but the problem still exists. It is always cold starting, so it takes about one day or two to get gps. No mater if there is a battery connected or not. Both batteries small and standby show 70-80% capacity but the last know location is lost. :-( Any ideas? Last year it was working flawlessly.
