When I received my two NodeMCU boards, I rapidly tried to update the firmware … and broke the firmware of one of the board. So here is the correct way to flash a firmware on a NodeMCU board which allowed me to save it.
I recently got an old computer screen out of my garage. It is now just perfect to monitor the extruder temperature and print progress from OctoPrint.
Today, I’m improving my previous article on RFM12 communication implementing a bidirectional communication between two BugOne boards.
To ensure a bidirectional communication is really happening, I’ll be using the code from BugOne’s github project: app_noapp_skel. This project basically takes any messages received by the RFM12 and sends it back reverted.
