Board at /dev/ttyACM0 is not available

I think I may have a faulty RN2483 module?

stupid idea… upload the blink sketch, does that work ?

also, after uploading the device sketch and before you open the monitor you must choose a different port

Yes, the blink sketch uploads fine and the serial window works fine. The only issue is the RN2483 does not seem to be returning data. Do you think I should contact shop support for RMA?

can you check this…

  • upload the passthrough sketch to the board
  • open a terminal (or use this free program) and see if you can communicate

btw I’ve seen the same behavior before with ubuntu in your log, opening and closing ports, what OS are you using ?

Ah, using the passthrough sketch with command mac get deveui I get response 0004A30B001BB460 :+1:

I’m assuming device EUI I need to register it on the network?

This can’t be the EUI since TTN EUI must be lower case right? What’s the command to obtain the EUI?

Yes, I’m using Ubuntu 16.04

http://ww1.microchip.com/downloads/en/DeviceDoc/40001784B.pdf

sys get hweui

if you get a response your TTN node is not defect, but the combination Arduino IDE/ UBUNTU connected to a 32U4 based module is not functioning as is does under windows

mac get deveui and sys get hweui both return the same string with capital letter. TTN won’t let me connect a node with capital letters in the EUI.

Thanks a lot for your help. I know I’m asking noob questions, I’m just starting out with TTN

that IS the hardware EUI

I did it here with passthrough and a terminal program

eui-0

eui-1

eui-2

eui-3

you see… the same HWEUI

if you (could) run the device info sketch on the TTN node it looks like this on the monitor :slight_smile:

devinfo

so go to the console and create an application and add this device
on the bottom of that page you see Example Code

copy paste that in the basic sketch and upload to the node
that’s it… data should be coming in if you are in range of a gateway

COM47 !! :smiley:

That’s nothing…I had com port over 100!

every new device and serial adaptor created a new one.
