Problem with reading Navpt #4

Closed masoudr closed 6 years ago

masoudr commented 6 years ago

Hi, I'm using the Ublox 7m module. I'm using this library and it has no problem. But every time I power up the module I need to upload Auto-configuration-mega.ino first and then I am able to upload Navpt example and receive the coordinates, But when I restart the module the gps.read() has no value and I should re-upload config sample again. Is there any fix for this? Thanks.

Hi, @masoudr!

Unfortunatelly, these ublox modules are configured from the factory to reset its settings when the power off. That's why there is a battery on the breakout board, it should be charged. You can find more about it in the docs here (section 8 Receiver Configuration).

I faced with the issue and it took a while to find how to deal with it, but the only thing we can do is to connect the module to the power supply. I created the auto configuration sketch to ease the process. So if you want to make autonomous device, you can integrate the auto configuration to the setup process of your microcontroller.
