Robonect Extension port - functions

[ldijon]

Hello,
Since a couple of weeks, I'm a new owner of a Robonect device for my HUSQ 320. I'm looking for the functions associated to the 10 pins Extension port of the Robonect. I see TX & RX and Gpios.
- Is there any way to "program" the Robonect through the serial port and the GPIos ?
- Can it be used to send "commands" to the Robonect ?
- Is the Firmware of the Robonect Closed or Open ?

I have also a question about the large 20 pins flat cable of the Robonect:
- Is there any picture with the pinout of the large plug ?
- Is it documented / accessible ?

- On the HUSQ 320 mother board, there are 4 Aux ports (with TX/RX and power pins). Does any one of you have already explored what we can do with these ports ?

Thank you & have a great day,

Kind regards,

Luc
