Hi there

I was just giving the whisper node a try, but I can't get it to show a COM port associated to it, in contrast to the Feather board I've also got.
At first I tried in a Linux machine and then (thinking it had sth to do with missing drivers and such) I tried in Windows with no luck.
I did configure the libraries and the board in the IDE.
I also installed the FTDI driver and tried the reset procedure as suggested in this post: [topic21 ... had to delete the URL because of an anti-spam measure since it's my 1st post...]

In my case the connection of the board doesn't seem to trigger any event in the OS, unlike with the Feather board which triggered a driver search by windows when it still didn't have the drivers installed or the showing of a new COM port in the Arduino IDE once the drivers were properly installed.
The board just lights the blue LED once per second as it apparently should. Except when performing the reset sequence, in which case it doesn't light, then blinks rapidly blue, then blinks yellow when releasing BT1 and finally goes back to blink blue once per second... which I think is the expected behavior.

At first I thought I must have been doing something terribly wrong, but now I reviewed the steps and I still haven't got luck.

I've got 2 whisper nodes and both exhibit the same behavior.
The Feather board works fine and can be programmed with both machines.

Please help! T_T

Hi Crvio,

I believe you're trying to connect the Whisper Node to you computer using the micro-USB port and this will not work. The micro-USB port is only for power, and all communication to the board needs to happen via the "Serial" pins.

In this case you'll need a working FTDI adapter (something like this: http://www.ebay.com.au/itm/FTDI-FT232RL ... 2344891772)

Once you connect the FTDI adapter to your computer, it should should a new COM port (or TTY if you're using Linux). This first step working, you can now try to connect the following:
Please note the VCC needs to be > 3.4V (5V is fine), otherwise the board will not power-up. If your FTDI adapter VCC is 3.3V or lower you can power the board with a micro-USB or battery in parallel.

Now once you open a Terminal window you should see the "Splash Screen" and if all pins are connected properly you also be able to program the boards.

Regards,

Thanks a lot for your answer!

I've ordered already one of those adapters and will be trying soon to program the board.

Thanks again for your help!
