Attached shows two Ixus 240 when inter-connected by Wi-fi
edit 1: The camera also seems to drop connection after some fairly short period of time.
Quote from: Hardware_Hacker on 27 / December / 2013, 21:42:39I don't understand. This is feature of the factory firmware, there is no reason it should not work.The subject of this thread is how to control the wireless from CHDK, and how to control the camera using the CHDK PTP extension over PTP/IP.QuoteCurrently scripts don't/won't run from CHDK PTP so this was ONLY an Demo/Attempt to See/Observe the Inter-connected Ixus 240 Wi-Fi cameras behave with CHDK also running on one of them.The basic idea was to use/test/demo the ("feature of the factory firmware") Canon's "Consumer" firmware feature's and the use of the CHDK Wi-Fi camera as a spy. But in this case no scripts can be run.H_H

But wait, there's more!On wifi enabled cameras (elph130, sx710, g7x at least) it turns out that sending PTP_OC_GetObjectHandles over PTP/IP allows getting past the "connecting" screen, and avoids having the connection time out the way it does if you just sit in the connection screen. The screen goes black like normal, but =post_levent_to_ui(4482) turns it back on, like it does for USB.On elph130, this makes it possible to switch to rec over wifi, and even use live view. However, attempting to shoot crashes immediately with:Code: [Select]ASSERT!! ExMemMan.c Line 1158in CtrlSrv The d6 cameras fail to switch to rec: The lens extends, but the display stays on playback, and attempting to shoot brings up a dialog about disconnecting wifi.edit:I got g7x to remoteshoot over wifi, by poking 0x8aa8 to 0 (based on code in fc0e03ae). One oddity: when this is used for rec mode, the camera menu + shoot sounds are enabled and the mute option in the canon menu is disabled. I normally have them muted. It goes back to normal on reboot.
Nice find(s)! I briefly tried PTP/IP (never attempted it before). I was able to connect to my M10, PTP_OC_GetObjectHandles and the 4482 levent worked as described. Also transferred a file, first time without USB. For some reason, I can't connect to my sx280 (it also gets IP from my router via DHCP, but the connection command just locks the chdkptp ui until it eventually times out).
If the PC was registered with your sx280 a long time ago, you might try deleting and re-adding it.
Wireshark might give an idea what stage fails.
