    Thanks for the detailed report, better than many other ones :)

    libti* and tilp do not support the CX II series, whose models speak a different protocol - technically, a variant of the NavNet protocol used by the earlier Nspire series, wrapped into the TI-Navigator protocol which uses UDP checksums. That new protocol is dubbed "NNSE". I started working towards NNSE support in libti*, at goal, and published the patches, but it was a while ago, and I'm still (infrequently) working on patches located earlier in the stack.

    The only choice for a third-party program implementing a narrow but important subset of the Nspire CX II series communication protocol - namely, file transfer - is https://github.com/Vogtinator/libnspire + https://github.com/Vogtinator/fuse-nspire . Besides CX II series support, Vogtinator's forks contain bug fixes which raise the original libnspire from its buggy, unreliable state, without changing the simplistic design.
