BlueFlyVario_Bluetooth_v9 Released

I have been shipping the BlueFlyVario_Bluetooth_v9 for a while but did not get a chance to blog about it. This is only a minor update to Version 8. A summary of the important changes from earlier versions is listed below:

Hardware Changes
  • I have added a small battery connector (Molex 1.25 mm) instead of soldering the battery to the board. The wires now wrap around the edge of a board in a small milled slot. This makes assembly a bit quicker and will allow users to change batteries without soldering.
Firmware Changes
  • The firmware now has a minor and major version. The $VER* command now responds with '$BFV MAJOR MINOR*'. The firmware version is currently 9.4.
  • I have included a bootloader. It is a slightly modified version of the ds30loader. At some stage I will blog about how to use the bootloader to update the firmware from a pc.
The circuit diagram and PCB layout for this release are shown below:

The way ahead

I am planning the version 10 hardware lineup with three models based on the primary external interface. These will probably incorporate a button instead of a slide switch. They are some months away I think.:

  • A Bluetooth model with battery similar to this model - designed for integration with Android devices. 
  • A TTL with GPS modules - designed for integration with devices such as the Kobo. 
  • A new USB model with battery - designed for stand alone use.
