Good Bluetooth Scanner

The scanner is relatively small and easy to handle. By Gummiering the handle
it does not slip out of your hands. The following labels were tested:
- Black and white: no problem
- Black on yellow: no problem
- Gray to light gray to yellow: no problem
- Black on silver: is not recognized

The scanner still get along with relatively low contrast. Our gray-on-yellow labels have a brightness contrast of about 20%. That was to be still recognized sufficiently to. Previously, I had tested the Pure Scan ML1 of ICO. The scanner could read the black-on-silver label, but failed in gray-on-yellow. Since I have very few read black-on-silver labels pro rata, the choice fell on the 7CI. Another shortcoming of ML1 is the use of special batteries. A spare battery for the ML1 costs about 45 euros. When 7CI standard AAA batteries are used. These batteries can be replaced easily.

The range is specified in the data sheet with 90 m. Within an area of ​​10x10 m size there are no problems. If a wall between scanner and notebook is, may cause transmission interference, even if it is not signaled by the beep. Then a lot of characters to be sent (in my case up to 126). A 24er brick wall was still no problem. Two walls cause transmission interference. Once you leave the transmitting range, the device will beep 2x. If you find yourself again within the transmission range, it will beep 1x.

Optimal reading distance: 10 to 20 cm

Disadvantage: Slightly delayed feedback (beep and vibration) of about 0.5 to 1 second for code detection. This leads occasionally to double sampling, because it is believed that the first scan attempt did not work out. This must be taken into account then when processing the received data.

The scanner has been tested on an ASUS Zenbook UX32V under Windows7HP and on a Lenovo Thinkpad R500 (Bluetooth Broadcom chipset BCM2045B) under Xubuntu 13:10 (Kernel 3.11.0). The scanner worked well on both devices.
