Hi folks,
we are testing our stm32L4 with a LoRaModule (SX1278 named as RA-02).
We always (tested with 2 boards) have a unexpected rising curve of the current after a TX-transmission or touch event.
If we push the RA-02 module to a side with little force or touches some pads of the module the current is falling to the real sleeping current(µC is sleeping).
But a few seconds later the current is rising again

. And the module is well soldered, we have checked every solder joint.
If we disconnect the vdd jumper brigde (only for this module) the current has a permanent low value. So the circuit after this vdd bridge to lora should be the problem.
What caused the rising current? Bad PCB? Bad Connections?
Thanks in advance for hints!
