How do I get access to the testbed ?
This is explained on the Getting Started page
Why are
I can't create links to/from nodes in the City of Things testbed in JFed.
How do I know which serial interface (/dev/ttyUSBX) is connected to what device?
If you use one of the 'CoT' Disk Images, symlinks are automatically created in '/dev' that will allow you to identify each serial port:
- OpenUSB: /dev/ttyOPENUSB
- EZRUSB@433 MHz/dev/ttyEZR433
- EZRUSB@868 MHz/dev/ttyEZR868
- EFM32GG+LoRa: /dev/ttyLORA
By referring to these symlinks instead of the /dev/ttyUSBX-devices directly you can be sure that you are talking to the correct device.
If you are not using one of the 'CoT' images, you can add the necessary udev-rules needed to to do by copying '/etc/udev/rules.d/50-persistent-usb.rules' from one of the 'CoT' images to your own image.
How can I flash/erase the EZRUSB devices ?
How can I flash/erase the LoRa device ?
I have a question and I can't find the answer on the Wiki
