The Bluetooth (at least) is not controlled by android, but by the mcu....so it is limited to which devices to be connected...there are problems connecting some ble devices.
Bit the wifi is not limited (as far as I know) perhaps is a not known issue about some frequency ranges in which your camera is broadcasting wifi that are not supported.
Several years ago there was a similar issue on some Android phones with dual wifi antennas not receiving 5ghz wifi signal due to the region of the phone (some regions limit the frequency range)
I think your issue is not a full dasaita fault....
Looking at your camera specifications it seems that you have not to connect manually the wifi to the camera...it is controlled depending on the purpose of the wifi by the Bluetooth of the camera...so you MUST to connect bluetooth first.
As you pointed bluetooth was never discoverable or you could not connect it by bluetooth....which points it on the first paragraph of this post....bluetooth is controlled by MCU and dasaita warns regarding compatibility of bluetooth devices to the headunit...perhaps you never noticed that.
Anyway you can not expect a full support (withou knowing from.which side is the issue) with the rudeness of your attitude you shown
