Connecting over Wifi to the GRiSP board

You need to modify some files in grisp/grisp_base/files :

• erl_inetrc :
  • in the line 4 {host, {X,X,X,X}, ["<host>"]}., replace {X,X,X,X} by your local ip address, for example {192,168,1,57}, and <host> by the hostname of you computer (you can see it with the command $ hostname -s)
• grisp.ini.mustache :
  • in line 5 replace MyCookie by your own cookie
  • in line 10 replace my_grisp_board by your own grisp board name
• wpa_supplicant.conf :
  • replace <wifi_name> by your wifi name (this name is case sensitive)
  • replace <pwd> by your wifi password

You also need to add to the /etc/hosts/ file:

X.X.X.X my_grisp_board

where X.X.X.X is the local ip of your grisp_board and my_grisp_board the name you give to it.

Then to connect to a board you need to enter this command in a command prompt:

$ erl -sname my_remote_shell -remsh project@my_grisp_board -setcookie MyCookie

by replacing project, my_grisp_board and MyCookie with you own values.
