Drivers

All BUG drivers can be found in the BUGlabs SVN.

The BUG3G driver (bmi_gsm) handles the basic operation of the module including:

  • Powering the module on and off
  • Setting the various interfaces
  • LED lighting.

Since the underlying modem is made by sierra, the we use the linux sierra driver v.1.7.14 (modified) for the device.


OSGi Services

The services listed below can be found in the com.buglabs.bug.module.gsm.pub package in the latest revision of the BUG javadocs. Each service is an interface with its own methods.


Native Apps
