Please note that the new TP-Link MR3020 V3 has a new CPU and it is not yet supported by the OpenWrt project ( https://wiki.openwrt.org/toh/tp-link/tl-mr3020 ) and the firmware available here is not working with it.
I’m aware of the problems on some of the iOS devices and working on a fix.
I made a test version that is tested in iTunes TestFlight.
I managed the fixed the 2 errors that where the crashing the application and if no other problem is reported I will submit the new version to Apple for review.
There is an error in the V0.3.4 desktop versions (Linux, OSX, Windows) that prevents the USB connection to work. Download and unpack the V0.3.4_fix archive into the V0.3.4 folder and overwrite the qDslrDashboard executable.
qDslrDashboard V0.3.4 is now available with the following changes
added BULB capture for Sony cameras that support it (needs the latest ‘Smart remote‘ on camera)
added custom bracketing for Sony cameras (A and M mode)
added Lumix GH4 (and probably other Lumix models that support PTP mode) USB connection (their PTP implementation is very basic, capture, change shutter/aperture/iso, browse/download images)
other fixes reported by users
I wish you all Merry Christmas and a Happy New Year.
