Re: [SailfishDevel] No QSerialPort
Thanks Chris and others, Indeed I need to use an external USB GPS and some other USB sensors. All communicate via serial ports. I gave the dmesg output txt as it is on other linux/MeeGo devices to show that I am not talking rocket science (simply plug in and use ttyUSB0 for (qt)serial communication). Never heard about OTG, and never had to use it for my app. Don't know why is there a difference between Sailfisch and MeeGo. My questions are now: Can I enable power on the USB port? (escape would be a battery powered USB hub) Will Sailfish automatically set a up a /dev/ttyUSBsomething when the device (like an external GPS) is plugged in? I will rephrase my question about adding the Qtserialport as a more general question on howto add Qt modules (also in the final package).

Re: [SailfishDevel] No QSerialPort
Actually support for QtSerialPort could be valid on non Jolla devices. For example if we get sailfishos going on BeagleBoard Black? or Android devices with USB OTG support... But I can understand if Jolla does not prioritize this right now, but it should atleast be available as extra repo or in mer-core or something?

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 From: devel-boun...@lists.sailfishos.org [devel-boun...@lists.sailfishos.org] on behalf of wsvries [wsvr...@xs4all.nl] Sent: Tuesday, March 25, 2014 10:46 AM To: devel@lists.sailfishos.org Subject: Re: [SailfishDevel] No QSerialPort Thanks, Alejandro Exojo schreef op 2014-03-24 21:53: El Sunday 23 March 2014, Wim de Vries escribió: So, it should be available in Sailfish.

I already told you that you might consider copying the module to your application and bundle it. Or see if Qt Serial port is packaged for mer, and ask for inclusion (or package if is not). Any Qt addon is a safe bet since qt- project has some serious commitment to ABI/API stability. I did this on the notebook Qt5.1 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. Or just explain what serial port you want to use and for what reason, so Sailors see the need to do the work themselves... and satisfy my curiosity. ;-) 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. r wim ___ SailfishOS.org Devel mailing list ___ SailfishOS.org Devel mailing list -- Skickat från Lenovo Thinkpad X230 running Kubuntu desktop ___ SailfishOS.org Devel mailing list

It's just that I had been using OTG on the other platforms (ubuntu/meego) without noticing it. You probably have not been using OTG on those platforms. There are no phones/tablets out there with Ubuntu (apart from a few you can flash yourself) that have OTG. Actually very few mobile devices actually support it, and even then most of those not out of the box but with hacks and mods for the power etc... Here I mean the ubuntu note/netbooks and the WeTab tablet. And for the fully functional 3D version I will have to switch to ubuntu phone. Several devices with OTG up there. Indeed some Ubuntu supported phones do, with mods most of the time. Although they are more exception than rule. Saw at least galaxy nexus, nexus7 and 10, but all to be flashed. Otoh there has been experimenting going on the Jolla to support host mode. (Which is OTG like, in the sense that the port gets manually switched and it does not deliver power unlike a real OTG port.) Power could be supplied via a battery powered hub, I guess. https://github.com/nemomobile/usb-moded/commit/44ebf5d79606a2ecb305e58ae71450dfe8853d16 More experimenting with this is expected to happen on some coming Jolla hack day to see if it can be made to work.
