VAYU M2M Capes

SW Images and Drivers

We provide active support for Debian Wheezy for all our capes. We are actively developing Android and Angstrom support and notes for these will also be here soon. To get started with our capes, you can take any of these paths:

• Use pre-compiled (all patches applied / driver installed) Debian Image. Click Here
• Compile Debian image from scratch and apply needed patches and install driver Click Here.
• Compile Android image from scratch and apply needed patches and install driver Click Here.
• Apply Udev and device tree overlays to existing Linux (Debian, Ångström, Ubuntu) installation in BeagleBone to get our cape working 'Coming Soon'.

Software Starter Guide

Covers steps to enable data connection on 2G or 3G capes, and also steps to use GPS PPS and NMEA messages with an application to setup NTP server.

Operating Systems supported (Debian, Ubuntu, Angstrom, Android)

We have tested the VAYU capes in the following configurations on different operating systems:

• Debian Wheezy: We provide full support for this. Pre-compiled images for both SD Card based use and for flashing to the eMMC are provided (see Section above).
• Ubuntu: We have tested our capes on Ubuntu. GPS (NMEA over serial tty port) is known to be working, PPS requires PPS support to be compiled in the kernel. The 3G modem (of the 3GH* and 3GC* capes) as well as the 2G modem (of the 2GD* and 2GQ* capes) have been tested to work on Ubuntu. We are in the process of generating Ubuntu images and making all configuration files available online.
• Angstrom: For Angstrom, we have done partial testing. There are no known issues except that the PPS support has to be additionally compiled into the Angstrom image. Once again, after having verified fully that they work, the configuration files will be made available online very soon.
• Android: We've been able to partially test our cape. Again, there are no known issues but we will put images and configuration files after fully verifying them.
