Greetings,

Matthias

Yes, that would have been my first question too.
Next step would be to measuer all the voltages on the pads going to the wp34s against ground. They all should be in the region of 2.5V to 3.3V. I am not sure about the rx line. that might be pulled low by the calculator when connected.

Good luck,
Harald
