Hi thkaw,

What header pins are you using for COM2? Did you try swapping TX/RX?

Chris

Hi Chris, sorry for late reply.

Yes, I tried swapping TX/RX. But both of my 2 pices Netduino 3's COM2 still unresponse.

Hi thkaw,

Have you deployed an app to your Netduino? Netduino 3 and Netduino.IP support power management--and so they keep the Wi-Fi chip in hibernate state until an app is running.

[In the future we may expand this power management to keep the Wi-Fi chip in hibernate unless/until networking code is needed...providing more available current for projects which don't use networking.]

Welcome to the Netduino community,

Chris

Sorry for late report.

Thanks Chris, it works !
