ios - CoreBluetooth peripheral identifier changes -

-

i using corebluetooth connect number of identical bluetooth scales i've developed using bluegiga ble113 modules. app keeps local copy of each scale's cbperipheral.identifier.uuidstring along related data physical scale can tell them apart. e.g. "scale a" , "scale b"

my trouble every device's uuidstring changes. can develop days against device, 1 day uuid different. scale hasn't been reset, app hasn't been restarted , bluetooth hasn't been cycled on phone.

i need way identify each bluetooth peripheral (scale) reliably , i'd rather not have hard code identifiers each device during production.

is there better method of identifying peripherals long-term?

unfortunately, dont think around ios's changing of peripheral uuids.

depending on control have change ble services/characteristics on scales, advertise additional service contains characteristic put custom identifier in.

on ios scan service , read characteristics value identify scale. way, not dependent on uuid os assigns peripherals.

hope helps!

SoapUI on windows 10 - high DPI/4K scaling issue -

Image
soapui doesn't seem dpi-aware , displays small on high dpi screen (tiny text , buttons). other applications running fine (screen resolution 3840 x 2160). version : soapui 5.1.2 os : windows 10 i have tried: configure soapui run "disable display scaling on high dpi settings" - parts of soapui looking bigger , don't display (image) changing resolution changing font size (preferences > editor settings > select font...) therefore assume, soapui pretends dpi-aware, not scale itself. have same issue? this workaround until developers round making version dpi-aware. step 1: add registry key hkey_local_machine\software\microsoft\windows\currentversion\sidebyside\preferexternalmanifest (dword) 1 step 2: add manifest file 'soapui-5.2.1.exe.manifest' in same directory 'soapui-5.2.1.exe' content of manifest file: <?xml version="1.0" encoding="utf-8" standalone="yes"?> <assembly xml
