Hi, We have been working on Soletta[1] for a few months and now that it has been open sourced, it makes sense to show what it can do using BlueZ. This implements a very simple node type that behaves as a Heart Rate Sensor in the peripheral mode. Just a overview about Soletta, it provides a way to write IoT applications targeting a broad range of devices (from the smallest edge to the smarttest hub). You would express your application logic using a Flow Based language to connect various nodes, write your custom node types using the libsolleta C API. And the Soletta developers would worry about porting the libsoletta library to the multitude of targets and providing a useful collection of node types. Using the support we already have in BlueZ for the Bluetooth LE peripheral mode, writing a Soletta node type for the Heartrate Sensor role seems a very good match. And it brings some very interesting use cases with the linux-micro target. The way I thought best about integrating BlueZ with Soletta was to add another mainloop backend using libsoletta so every event would be handled consistently. See patch 02/13. Most of the changes not related to either adding the mainloop support, or adding the node type code are related to some lack of configurability to the peripheral code, perhaps having a way to the callback that will register the service to have a say in some parameters? The most important question is: is BlueZ the right place to have this code? What do you say? Any questions about the project, we are hanging out in #soletta @ freenode.net.
