Hi,
I have both TI-Connect and TiLP, to send files to Nspire i normally use the link program,
but it doesn't detect while my calculator is with the TI-84 Plus keypad,
so I tried to send those files with ->right click over the file, then send to TI Device, and i don't know exactly which program has this feature, but my guess is the TI Connect.
The OS in the calculator is N Spire 1.7
and the TI Connect do recognize my calculator as a TI 84 plus.
I hope isn't missing any information now.
