I managed to get the RFM69Pi extension board working on a RPi 3 B after disabling the console and swapping the serial aliases (Also see: http://spellfoundry.com/2016/05/29/configuring-gpio-serial-port-raspbian-jessie-including-pi-3/#History).
Now, when running minicom on /dev/serial0, I can interact with the board.
Pressing ‘v’ returns: [RF12demo.12] A i1 g1 @ 433 MHz
Pressing ‘h’ returns: The list of available commands.
I’ve been switching between (0x - decimal, 1x - hex and 2x - hex+ascii).
I am trying to find out now whether the output is okay. In decimal logging mode (1x) I get quite some logging, all lines are preceded by a question mark. Is this what I should expect? What would be the best way to start interpreting the data? Is there any documentation available that could help?
My (initial) goal is to record and playback commands from some RF remote controls that I want to replace.
