Beaglebones + RadioMaster R16X Receivers Levels

After some times trying to use this receivers on beagles - Beaglebones Black, Blue and Pocket, I finally discovery what was the problem.
On every docs about beaglebones, the high level of the gpio pins is described as above 2volts is considered as a high level.
The R16X dbus outputs is 2.2 volts and beagles didn’t recognize this level, so to use this receiver with beagles, I had to use a shift-level circuit, using 3.3 volts as high and low voltage power supply.
I didn’t try the sport with telemetry, but I think the same problem will happen.
