I can't use ATOM GPS Kit

[Kei]

Hello there, thank you for reading.

I live in Japan.
I want to use M5Atom GPS kit to record GPS information.
But it doesn't work at all.
When I write the following code into the GPS kit, it always outputs 0.

Hello @Kei

how long did you wait? Do you get all zeros in the debug output as well?

When I haven't used my M5Atom GPS kit for a while it takes a couple of 10 minutes for it to get valid data. It also helps being closer to the window or outside.

Thanks
Felix
