Yeah I'm getting a similar error right there on OSX about a CoreAnimation in queue that was deleted before it finished -- but OSX just plows through it anyways..

I think I've wired up something funky in the new selector dialog init -- I'll take a look shortly and debug that error here.

[UbhaSecurity]

Thx :)

[cjcliffe]

yeah according to the interwebs I'm initializing a UI context from the wrong thread.. sounds like I'll just make appFrame launch the selector instead! :) fix coming shortly..

@UbhaSecurity latest push should do the trick, was jumping around between raspberry pi remote devices and locals with the new dialog last night without much trouble :)

Remotes will eventually save, but I need to decouple it from the local devices and allow it to build the device list asynchronously as they finish querying. That way you won't have to wait for all the remotes on startup and just jump to a device when it's ready.

@UbhaSecurity wasn't fixed in latest commits when I tried in linux here; should be actually fixed now.

Can't reproduce this one anymore here.

Hello, I’ve just found out about this program and got the same error on a current Arch Linux install after compiling from git

@Koatman I see "Available factories...nullJust 'null' factory found." -- I think this is related to the new Alert dialog that's supposed to warn you when there's no modules found. I'm betting if you install SoapyRTLSDR, SoapyRemote or whatever Soapy module for your device it will bypass that error..

Will patch that up -- I likely called the alert dialog from the wrong thread :)

[Koatman]

Correct! I installed the BladeRF soapy module. The program runs now. Thanks!

[cjcliffe]

@Koatman excellent, I'll add an issue to fix the new crash you encountered as well. cheers!
