Qt Serial Port: Android, iOS - will it work ?

[pit.garbe]

So, I got the documents. Data sheet and instructions. After reading them it's clear that paring is definitely only for HID mode. I sent a followup to both the person who sent me the docs and the one who apparently wrote the instructions, asking for a way to disable HID mode altogether.

Btw., I just now realised that you probably speak German ;)

@pit.garbe BTW: have you tried to change the switch on the device to computer instead keyboard ? does this help on iOS ?

info for all waiting for my Qt 5.8 - QtQuickControls2 - Bluetooth LE Example APP:

• finished all the work for BT LE Scanner to inspect devices, services, characteristic, descriptors and to try out read, write, notifications
• finished my work for a customer project using a custom device to scan pegel of mobile networks (this won't be open source)
• finished my work for a customer project using the Addimat (waiter lock) for user login-logout
• working on HeartRate and another example
• working on device-specific settings and device-favorites to make restart app easier with auto-connect to devices and notifications

then have to write the blog to provide some documentation
expect blog and app at github next week

So, I just found out by accident how to fix the popup issue.

Simply pair the lock once as a keyboard, then navigate to the Bluetooth system settings and remove the lock there ("ignore this device"). Then it will not try to connect to the iPad again by itself. Presumably because it has its own list of known devices and the iPad is now ignoring all incoming connection by the lock.

It can only be connected to this iPad as a keyboard again after clearing the pairing list on the lock itself. This can be done by putting the little selection dial on the bottom to the third, unmarked position (not "COM P" and not "Key Board") and plugging it in again, then off again and turn the dial back to one of the other positions and plugging it in again.

The iPad will then be asked again to enter the PIN upon connecting to the lock.

So, for us its perfect. Disable once and never be bothered again. Even from the iPad settings screen its impossible to reconnect again (by accident).

That didn't help. And I think its a switch between COM (serial port) and USB HID mode. It doesn't affect the Bluetooth features. Only the third setting disables Bluetooth altogether, and, as it turns out, is used to clear the pairing list.

will do this next time testing the lock on iOS. Doing all my work on Android and only from time to time verify if all works and looks good on iOS, too
