MEMS Sensor dead??

Post by etv99 »

Hi,
I just bought the Freematics ONE+ Traccar and I figured out, that my adapter is not waking up when the car is moved.

When flashing the image for data transmission to the freematics hub, I get there no acceleration data when shaking the adapter...
I'm using the telelogger.ino in firmware_v5

...btw, YES it's enabled in config ;)
and yes I'm using the latest files from github https://github.com/stanleyhuangyc/Freematics


what can I try?

Thanks
Tom

Please check serial output. Do you have MEMS:OK or MEMS:NO. Note that data is submitted to server once a second and you may not be able to see instant data change from web page.

Hi,

thanks for your reply!
I get MEMS in the serial Output.

I tried again with my traccar setup (only changed the server) and now I get the values again!

But my connector would not come back from sleepmode when I "shake my car". I have set the wakeup level down to 0,1 but have no wakeup.
Also when I start the car there is no wakeup.
Battery without ignition/motor off is 12,8 V, with on it's over 14 V.

thanks
Tom

Have you checked serial output when ignition started?
