Hello, I've found work-around SkySafari 6 Pro setup for connection with Temma2Z via Bluetooth.
1. Select 'Demo Interface' in Scope Type.
2. Set 'Set Time & Location' on
3. Select 'Takahashi Temma 2' in Scope Type
SkySafari (3) Pro release 1.8.5 has no trouble with Temma2Z without Setting time & location.
SkySafari 4 Pro has the trouble as same as SkySafari 6 Pro, but step1 is not necessary. step2 can be always set in scope type - Takahashi Temma2.
SkySafari 5 Pro needs the work-around as same as SkySafari 6 Pro.
Temma2M has no trouble, but Temma2Z has the trouble. I faced it a few years ago.
I checked the serial command from SkySafari via bluetooth on PC terminal software,
I use RN240/270 by Microchip Technology for bluetooth - UART converter.
SkySafari 4,5 and 6 Pro sends $$$ at first, then E<CR,LF> without Setting time & location.
SkySafari 3 Pro sends $$$ at first, next PS <CR,LF>, then E<CR,LF> without setting 'Set time & location'.
Setting 'Set time & location' on, SkySafari 3 Pro sends $$$ at first, next I<+/-latitude><CR,LF>, next T<time><CR,LF>, PS<CR,LF>, then E<CR/LF>.
SkySafari Pro 4,5,6 sends $$$ at first, next I+<latitude><CR,LF>, next T<time><CR,LF>, then E<CR,LF>.
There is PS between $$$ and E, so that SkySafari 3 Pro has no trouble even if setting 'Set time & location' off.
It seemes that longer time needs a bit between $$$ and the first command, because Temma2M is working on the same algorithm,
or remove $$$ which is Bluetooth Data module Command by Roving Networks.
Could you please check and improve it for the next release?
