Version 5.6 of qt5-qtconnectivity, was introduced in the July 2017 2.1.1/Jämsänjoki update, and it's been good so far for developing BLE-capable apps. However, it has some significant restrictions that have been addressed in 5.8, such as the ability to scan for BLE devices separately from BR/EDR devices, and the ability to control the BLE scan timeout.

Are there any plans in the pipeline to upgrade qt5-connectivity to 5.8?

Am I right in remembering that 2.2.0 will upgrade Qt to 5.8?

This would be great if it's true. Can you find a reference to it anywhere? The closest I could find is this comment by @sledges during the April collaboration meeting:

"Emoji keyboard will already be in 2.2.0; color emojis come when we move to Qt 5.9."

This tells me that 5.9 is coming after 2.2, but that doesn't contradict what you say!

My understanding is that Jolla will go directly from Qt 5.6 to 5.9, both which are LTS versions. They aren't keen to upgrade Qt unless necessary. In addition Qt 5.8 support ended in January 2018 according to the version history on Wikipedia.

Thanks @luen, that would make sense then. Assuming both pieces of info are true, we can conclude there won't be a Qt version upgrade until after 2.2 (due some time this year). However, not all the Qt components are in sync, so it's still possible qtconnectivity will be upgraded independently (maybe even earlier, if I'm being crazy optimistic?!).

@flypig Now that you post that, I think that's where I read about the Qt upgrade (to 5.9 and not 5.8) and connected it with 2.2.0, so please forget what I said before.

You can have more details in It is clearly Qt5.9 that is targeted because of the LTS nature but that will not come in May (2.2 upgrade) but later in the year and likely after summer...

Target is SailfishOS 3.0 The speed improvements and new Webengine all indicate that.

The video is worth watching in full, but the question of updating to Qt5.9 happens quite a way in at 37:39.
