Not long ago, the sharing of bicycle guidance opinions or management measures in Beijing, Tianjin and other places was introduced, and the sharing of bicycle configuration satellite positioning became a rigid regulation. After the policy was introduced, ofo said that it has jointly developed smart locks with Beidou Navigation, and the smart lock of Beidou navigation chip has been developed and equipped to some small yellow cars.

After the introduction of this remark, all circles have raised questions. Some users said that they have never seen a small yellow car equipped with a smart lock. There are also media field investigations, and it is found that the vast majority of ofo small yellow cars still use mechanical locks, and vehicles equipped with smart locks are rare. Then, the small yellow car equipped with "smart lock" is really "smart". A professional reviewer evaluated it with a rigorous scientific attitude and came to the surprising conclusion that the ofo smart lock does not have a navigation chip at all, and the so-called dynamic password actually does not change for a few hours... so-called intelligence The lock, in fact, has almost no change from the previous mechanical lock.

During the evaluation process, the assessor found that the outer casing of the ofo smart lock is very thin and can be easily dismantled. In the past, the ofo mechanical lock was the “hardest hit” of man-made damage. In addition to the quality of users, the quality of its own products and loopholes could not escape. .

The positioning chip installed in the circuit board is the core and most critical component of the smart lock and even the entire shared bicycle. The professional reviewer found that the ofo "smart lock" only has the Quectel M26 module, which is a GSM/GPRS chip. There is no legendary "Beidou navigation chip". It seems that the so-called intelligence relies on this M26 chip. It is.

According to the professional introduction, it is mainly based on GSM/GPRS, which means that the positioning function is based on the triangular positioning of the mobile cellular base station, the degree of deviation is large, and there is still a long distance from the precise positioning. . So "the golden jade is ruined", let the professional appraisers also sent out the feeling that "no wonder ofo throwing out the concept of red envelope area, can not accurately locate each car!"

The reviewers also went to Quectel's official website to try to find more information about the chip. They couldn't find it on the whole network. If the chip is not fake, then it is at least one product model that has been eliminated. In this way, the positioning ability is not strong, and it is far behind the products of the times. It was actually used by the ofo to decorate the facade.

After the restore lock, the tester also tested whether the "smart lock" password is really a dynamic, random password as ofo. The result is also disappointing: the password is the same after 1 hour, it can be opened, it can be opened after 2 hours, and it can still be opened after 5 hours - the so-called dynamic password is also a blind. And the mechanical lock before the small yellow car, it can be said that there is no change and progress.

Under the high pressure of the policy and the doubts from all walks of life, the so-called "smart lock" that has been rushed to the horse has been proved to be illusory, and the previous public relations of theo have been hit. Then, what is the next ofOo to continue to install this kind of pseudo-smart locks for the small yellow car, or continue to under the pressure of all walks of life to really develop a real "smart lock"? Ofo once again caught in a dilemma.
