Command line for Feather RFM95

[mike_adafruit]

I am trying to upload, using the command line, binary files created in the Arduino IDE (under Fedora Linux) using a command like

Code: Select all

/home/mg/.arduino15/packages/arduino/tools/bossac/1.7.0/bossac --port=ttyACM0 -e -w -R dev/Feather/Feather_9X_TX-single/Feather_9X_TX-single.ino.feather_m0.bin

It seems to work OK, however I am forced to put the Feather into programming mode (double tap of the reset button).

Is there anyway to avoid that step? (after all, the IDE does it fine!)

Thanks.

To auto-reboot the microcontroller and make it launch the bootloader, you have to open a 1200 baud Serial connection and then close it again. That's the secret-knock the Arduino IDE uses with microcontrollers that handle USB internally.

Can you suggest an incantation over command line to open and then close that kind of connection?
