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.

Today I test Netduino 3,

In spec, it said which have 4 COM Ports

I test COM1,3 by using UART Camera.

And it works fine, read all information and data i need.

But in COM2, it won't have any respond.

Not detect any UART device.

But same program change to using Netduino Plus 2, it working.

So I change a brand new Netduino 3, and test COM2.

But still can't using only COM2.

Is there have know issues in Netduino 3 COM2?

My Camera baud rate is in 115200

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 !

Hi, today i want to connect netduino 3 wifi to WIFI AP

but with unsuccessful.

I can't find any specific document telling about wifi connection step.

So I search on this forum.

Understand probably using MFDeploy to set.

I starting do following step to set netduino:

1. Connect my netduino 3 to PC, open MFDeploy.

2. Confirm netduino 3 is connect correctly and can send command.

3. Open Network configuration dialog.

4. Fill value like below image(Connect to my none encryption WIFI ap, here is my sony Z Ultra)

5. Press Update, then nothing happen, ACT LED always keep off, and WiFi ap also not see any client connect.

Please help me check if some step are wrong or miss.

Thanks!
