SODAQ Univeral Tracker v3 / External LED


i have a question about the SODAQ Univeral Tracker v3 / LORA.
I add a external LED-bar (3-LED) on D12 and Ground.

Everything works wonderfully, but he does not send any data at night and then sends it back sometime in the morning. Can someone help me ? If the LEDBar is not connected, everything works fine.


Hi @Philipp_Luond,

Can you do a test.
Before sending you turn off the LED-bar and turn it back on after sending?
Maybe the LEDs raw to much current and your power supply can’t deliver enough for both sending and having the LEDs on.

Best regards,
