I've done some more experiments with a Texas Instruments OMAP-based h6315 PDA-phone combo today to find out more about TI compliance. As was easy to predict, it was, again, only the standard 2.3 and the deluxe 3.1 versions of NoviiRemote that was able to run on it. (Note that, unlike with all the other four test devices, it errorenously assumed COM6 to be the IR port on the 6315; it must be re-set to COM3 manually.)
Interestingly, it was only the more expensive Deluxe 3.1 that was able to emit the off/on signal of the LG air conditioner on both the Samsung and the TI device; the standard 2.3 version wasn't. The button, after emitting the signal, just got sticked and made a soft reset unavoidable. (The other – I've tested the pre-defined Pana and JVC VCR databases – devices I've tested worked just fine.)
The same Novii 2.3 worked just fine on both Xscale devices (PL720 and iPAQ 2210 – don't forget it doesn't support the CIR mode of 2210; therefore, the range is really bad!) in this respect. The StrongARM-based iPAQ 3660, on the other hand, had the same problems as with the air conditioner signals than the iPAQ 1940 (Samsung) and the h6315 (TI).
Therefore, if you have a TI, a StrongARM or a Samsung CPU-based device and want to save $10 on going for the standard version of Novii instead of the deluxe one, test it with all your remote controllers and functions before buying!
