Got a new toy: Canon EOS 6D. Provides Remote Capture via WiFi and iOS or Android app. Camera provides AP @ Jolla connects to this AP, Camera is pingable from Jollas terminal, however the Android app will not see it. Any ideas? Anything I coud try?

I have an android app with udp and also one with tcp connection working. So maybe your device uses some proprietary protocol which conflicts in alien dalvic. Can you find some more network specific details for your device on net or manual.

Protocol is called PTP/IP, TCP on port 15740. Defined in ISO 15740. Detailed description here:

Most likely wifi is turned off in android settings for some reason. Canon CameraWindow started to work after I applied this sqlite fix:


As devel-su "root

systemctl stop  aliendalvik.service

echo Current setting:
echo "select name,value from secure where name = 'wifi_on';" |sqlite3 /data/data/
echo "update secure set value = '1' where name = 'wifi_on';" |sqlite3 /data/data/
echo Updated setting
echo "select name,value from secure where name = 'wifi_on';" |sqlite3 /data/data/
systemctl start aliendalvik.service

Some people managed to get it to on by reinstalling android support on wifi (this will lose all android application settings).
