+# Hints
+
+This document contains a collection of (maybe) useful hints and commands
+for developers to do various task inside the installed SECO North Yocto.
+
+This is a growing document and not ment to reach any state of completeness
+like a manual, or similar.
+
+## Bluetooth
+
+Bluetooth is currently only basically supported.
+Commands used for a basic hardware test:
+
+### Tanaro V1.1
+
+*Note*: There are devices which do not have R11 populated on the BT Uart's CTS line.
+       These do not support bluetooth.
+```
+# Verbinden des BT-Chips
+rtk_hciattach ttymxc3 rtk_h5
+
+hciconfig hci0 up
+# Scan for other BT-devices
+hcitool scan
+```
+
+This currently does not work with yocto kirkstone.
+
+## Video playback
+
+### VP9 playback from qml
+
+```
+qmlscene /opt/ltp/scripts/video_playback.qml
+```
