nRF52840DK Bluetooth Mesh Light-Switch Example with Virtual COM Port

[ahboyboy]

Hi All,

I have loaded in the Bluetooth Mesh Light-Switch example and it works well.

For now, I would like to read out the received data from the switch node (client) to computer (COM Port) via the USB port on the development kit. Is it feasible?

If this is feasible, then what is the baud rate, data bit, parity and stop bits?

I tried to load in the bluetooth mesh serial example but it does not seem like working as I intended.

Thanks in advance for helping.

Hi. 

What data would you like to read out? The native example will output some data. 

When testing the Light Switch Client/Server I get this output using the debug window in SES (You can also use i.e RTT viewer):

Output on server:

 

Here you can see the output from the example started, the provisioning and receiving a message from the client. 

Output on Client:

Hi, thanks for your response.

Yes, I managed to get the output through RTT. However, what I intended to do is to use USB Serial COM port to get the data so that I can process the received data through my own desktop program then send to cloud, in other words, I cannot retrieve and process the received data from RTT. Is there any other ways to do so?

I see. 

Then I would suggest taking a look at the serial example.

Could you elaborate on this? What do you mean by "not seem to be working as intended"? 

Best regards,

I loaded the Bluetooth Mesh Serial Interface Example to nRF52840DK and linked it to PC via USB. I then opened the Terminal Program (I tried with RealTerm in Windows and CoolTerm in Mac) nothing was shown. I am not sure whether the baudrate and the configurations are correct or not, thus I was asking the configuration for baudrate, data bit, parity and stop bits.

Hi. 

You can find more information about how to test the example here; 

"3. When the the serial example is running, start testing it using the Interactive PyACI. Refer to the Interactive PyACI documentation for details."
