| - | ====== Blocking WiFi from starting ====== | ||
| - | Since codex 1.2.0.344, the reMarkable has developed an annoying habit of turning Wifi back on after you start it, even if you had manually turned it off before. | ||
| - | |||
| - | **Edit: the tip has been obsolete since this issue was solved with the version 1.5.1 of codex, released on 17 September 2018** | ||
| - | |||
| - | This is a quick hack to try and block Wifi on start up using rfkill in / | ||
| - | |||
| - | - Create a file called / | ||
| - | < | ||
| - | remarkable: ~/ cat / | ||
| - | #!/bin/bash | ||
| - | exec 2> / | ||
| - | exec 1>&2 | ||
| - | echo " | ||
| - | set -x | ||
| - | | ||
| - | mount /home # need /home mounted to be able to look through the metadata files | ||
| - | WIFI_STATE=" | ||
| - | rfkill list | ||
| - | if [[ " | ||
| - | then | ||
| - | rfkill block 0 # disable wifi | ||
| - | else | ||
| - | rfkill unblock 0 # re-enable wifi | ||
| - | fi | ||
| - | | ||
| - | echo " | ||
| - | exit 0 | ||
| - | </ | ||
| - | - Mark the rc.local file as executable | ||
| - | < | ||
| - | remarkable: ~/ chmod +x / | ||
| - | remarkable: ~/ ls -la / | ||
| - | -rwxr-xr-x | ||
| - | </ | ||
| - | - Create an object in the reMarkable files to use as a control. I created a top-level folder called " | ||
| - | - Reboot the reMarkable and see if the Wifi remains off. | ||
| - | |||
| - | To re-enable Wifi, rename the control object through the UI to Wifi on (or anything really as long as it doesn' | ||
| - | |||
| - | This seems to work for me. I don't use Wifi at all except to search for reMarkable firmware updates, or when backing the device up, in which case I am happy to go through a bit of awkwardness to turn it back on. | ||
| - | |||
| - | The script should write to / | ||
| - | < | ||
| - | remarkable: ~/ systemctl status rc-local | ||
| - | ● rc-local.service - / | ||
| - | | ||
| - | | ||
| - | Process: 178 ExecStart=/ | ||
