How to enable FTP server for Xiaomi Yi camera.

First of all enable telnet (put an empty file named "enable_info_display.script" to the root of microsd and reboot). Login with root using your favorite telnet client.
Then run this command to start FTP server (thanx to nikulin for update):
nohup tcpsvd -u root -vE 0.0.0.0 21 ftpd -w / >> /dev/null 2>&1 &

Connect using FTP. Works in both AP and STA modes.
???????.
PROFIT:

File transfer speed via FTP is up to 1MB/s.

Xiaomi Yi camera firmware v 1.2.0 released. Noise filter is off.

Xiaomi has released 1.2.0 firmware for Yi camera. I found one interesting thing not listed in official change log (left - 1.1.0, right - 1.2.0):











Noise filter is disabled by default in LOW ISO mode (more about Yi camera modes in future posts).

Xiaomi Yi camera hardware mods. Aluminium case.

I got aluminium case with UV-protection filter kit from ebay. 

Pros:
  • It looks great due to semi-gloss black anodized aluminium coating.
  • Very easy to install camera into it.
  • Protection of camera lens and body.
  • Shoe mount on top - great for dashcam use.
  • 5 1/4" mount holes on the sides.
  • It gives better grip for the camera.

Cons:
  • Kit filter shows severe vignetting. 
  • Shoe mount and 1/4" holes on the upper and lower sides are not aligned with optical axis of the lens.
  • Suggested camera fixation method doesn't provide a solid result.
  • Mic hole of the camera is blocked by the frame.
It seems like the manufacturer of the case uses preforms for one of GoPro camera. That's why there is a mismatch of mount and mic holes. So I recommend not to rush off with buying of this case and wait until some design adjustments to fit Xiaomi Yi will be made.
