I've started working with the AT86RF233 a few weeks ago and found the Ranging Toolbox (RTB) package quite impressive. It's the first time I'm using wireless modules, so I wanted to see if I could use the Phase Difference Measurement Unit (PMU) for another usage than ranging.

My problem is that I can't get the PMU value. Even trying just to print the value during a ranging of the original RTB firmware doesn't work. I noticed I had to set the pmu_en flag, but this didn't change much. I just get values between 0 and 20 instead of the expected 0 to 255. When pmu_if_inverse enabled I just get 0.

Has anyone experienced the same problem? Or is there some working code using the PMU I could read?

So basically while being in the advanced RX-Mode (RX_AACK_ON) it is not possible to measure the pmu. You have to be in RX_ON
