In SX1261/62 documentation there are mentioned registers for non-standard DIOs control with information that those registers should be only used with “Semtech-provided code samples”. Where those code samples can be found or requested?
Is it actually possible to use DIOs as inputs and control some transceivers functions using digital inputs? Maybe it’s possible to start TX or RX using one of those pins as input. Such option would allow to achieve more precise timings than using SPI transfers.
