How to gather your app data from your mote on your own

Hardware you need

• 2x OpenMotes
• 1x OpenBase
• 1x mini B cable
• A computer running the OpenWSN environment installed

Procedures 

• Program two OpenMotes
  The uinject application running on the mote generates dummy data (a counter value increasing at each packet) every 30 seconds and sends it to the manager.
  By default, this app is disabled. You can enable it following those procedures. Compiling them and download the code to your motes after you did those modification.
  
  • uncomment this line: https://github.com/openwsn-berkeley/openwsn-fw/blob/develop/openapps/openapps.c#L44
  • add uinject at defaultAppsInit structure: https://github.com/openwsn-berkeley/openwsn-fw/blob/develop/openapps/SConscript#L34
• connect one to your computer and power on the other one
• on your computer, double-click on uinject_dagroot.py (folder openwsn-fw/openapps/uinject)
  you need to change a little bit in uinject_dagroot.py to make it work on your computer
  
  • change the serial port according to your case: https://github.com/openwsn-berkeley/openwsn-fw/blob/develop/openapps/uinject/uinject_dagroot.py#L234

  • add following code at : https://github.com/openwsn-berkeley/openwsn-fw/blob/develop/openapps/uinject/uinject_dagroot.py#L159 (this is only required for OpenMote)

    self.serial.setDTR(0)
    self.serial.setRTS(0)

  • change the length to 73 as we add Ip-in-Ip structure in the packet which increased the length of packet: https://github.com/openwsn-berkeley/openwsn-fw/blob/develop/openapps/uinject/uinject_dagroot.py#L205
• That's It!

Result

The uinject_dagroot.py application prints on screen what you are receiving from the other mote, which is the counter value increasing from 0. Once the printing works you can:

• make uinject fancier to include real sensor data. I would recommend to then rename the application
• make the uinject_dagroot.py fancier and log/send/tweet the received data
