As a final step in exploring the optimal settings for receiving “foreign” OOK signals with the RFM69, the settings for DAGC, Sensitivity Boost and the effect of the Modulation index are explored. The modulation index is actually a FSK aspect, and no effect should be expected for OOK. However, as it can be programmed to High or Low, it is included in the exploration.
Foreign OOK refers to signals that are not natively produced by an RFM69, but are originating form various sensors or remote controls.
From the first results, it can be concluded that Sensitivity Boost has a clear advantage, and also DAGC enabled helps in icreasing sesnitivity:
