[SailfishDevel] No QSerialPort

[Jonni Rainisto]

Hi,

I hope that you are aware that USB OTG is not supported, so you cannot attach USB serial devices to Jolla? Or are you building yourself a custom TOH with USB host support and plan to use i2c serial ports? In that case you can just compile QtSerialPort code yourself (I've tested that it compiles just fine inside the SDK) and bundle that inside your application.
You might want to consider BT devices and using RFCOMM over that as that would be much simpler approach.

br, Jonni

I thought Sailfish would include all modules of Qt....

I did this on the notebook Qt<5.1 versions of my app. (even a
boost-serial version before QSerial)
But doing this with Sailfish is far more complex:
it has to be available on the Mer VM and the Sailfish VM (and later
Sailfish device).
I am not experienced with VMs. The nice thing about using Qt is not
having to worry about the implementation (and updates) of the modules.
(The Sailfish (Target) manager is also not able to find the serialport
module).
I need all the time for porting to Sailfish, esp. C++GUI2Qml  ;-(
So, support for this module is a must for my app.

aircraft navigation+more app:
USB/serial device1:
-external GPS
USB/serial device2:
-air press sensor (altitude)
-humidity sensor
-temp sensor
No rocket science, works flawless on ubuntu notebook.
