3.3.2 has been just released.
It is more robust that the previous version and has an improved Walkera (PCM) support.
The robustness was achieved by some code changes and by moving to a newer development environment.
The improvement in the Walkera PCM algorithm is the result of co-operation with Mr. Eilert Johansson who found and fixed several bugs in my original algorithm.
If you already use SPP with a Walkera PCM transmitter, I urge you to upgrade to SPP v3.3.2 (You will have to re-calibrate first).
I'd like to thank my Alpha testers for their time and effort.
