Needs an additional pin, maybe some pull-up/down - unclear...

Consider implications of using the STM reset pin.

Consider implications of detecting STM software reset since the STM Reset pin is pulled somewhere on software reset. It would be nice to have a latching LED if software reset happened. Pressing hardware reset would not set the LED, it would reset the latch.

7.2.2. Manual Reset A manual reset of the SX1231H is possible even for applications in which VDD cannot be physically disconnected. Pin 6 should be pulled high for a hundred microseconds, and then released. The user should then wait for 5 ms before using the chip.

Note whilst pin 6 is driven high, an over current consumption of up to ten milliamps can be seen on VDD.

RESET on RFM is active high (ridiculous) - I can't tie them together
