Inkspace support with Bamboo devices [Android App] [answered]

Ahh that would make sense, BT is not something I use, so I likely missed it as a feature that is not supported in Alien Davlik. Thanks for the tip

To expand into more details :

• modern android devices uses BlueDroid to handle bluetooth.
• GNU/Linux distributions (like desktop or in this case like SailfishOS) use bluez instead.
• Your android application want's to control the bluetooth connection directly.
• But nothing is providing bluedoird's API to it inside Alien-Dalvik
• So it doesn't work.

(What will work is device who are automatically handled by Sailfish OS and presented as some standard interface inside android apps :

• Bluetooth speakers are handled by bluez and pulse audio, and show up as an audio out. Spority can play to this audio out without ever knowing that it happens to be over bluetooth.
• Bluetooth keyboards are handled by bluez and libinput, and show up as a standard input. WhatsApp can use this keyboard to type messages without having a clue about bluetooth being used behind the scenes.
• Saddly there's no such standard "consumer of user-interaction event" protocole that the Bamboo app could use, so it tries to have a direct access to the bluetooth stack, but doesn't find anything responding to the API it expects).

Note : VNC is an exemple of standard networked procotol to send user-event over TCP/IP, but it doesn't handle all the advanced features you would expect from a drawing app ("pressure" signal, multi-touch, etc), only standard clicking events.

@DrYak,

Thank you very much for that explanation. The interesting part is that the Wacom Bamboo smartpad, does sueccessfully connect to the phone via bluez, however it does not pull the files, which I guess could technically be done with a ported version of https://github.com/tuhiproject/tuhi/ which is outside my technical scope, but might be worth someone to explore.
