Hi,

I have trouble with the measurements. When I start the sensor I get correct values. After 2-3 measurments the display switch to a scarry pricture. Also over LoRa I get from this moment static values for each data-transmission.

so I have the following pic:

avg min max
4B(C) -inf -inf -379.
2B(Z) -inf -inf -379.
3
TTN ok

After a reboot thesame effect.

Do you know this effects?

Thx, Steffen

Hi, These values I recognize, when I made a mistake in wiring the MEMS. In your situation in the begin the values are correct, so I Think it is not the wiring, but maybe a weak power supply. Try to comment out the loraSend (2 places in the .ino file). The loraSend takes some power.

Typical Problem between chair and solder iron. GPIO35 should be used, not GPIO39 🙈

I found the mistake while shortening all wires. It works, thx and sorry.

Now I will wait that TTN ok appears, what's are the reasons for the message TTN fail, while I can see the right values in the TTN-Server?

I checked the code, the TTN fail/Ok is one cycle behind. This can be improved in the next version.
