This product is a starter version and can be used for testing and small batch deployments.

 

  The application of ibeacon here first illustrates a few issues that everyone is more likely to misunderstand:

     1. Some customers have reported that Apple's application locate ibeacon is not accurate, and Airlocate cannot find the device?

It is explained here that Apple's software judges the distance based on the signal strength of its own product. Our product signal strength is different from that of Apple's official, so customers can use Apple's source code to determine the distance by themselves. iOS sample code AirLocate-https://github.com/volca/AirLocate. Our company's official software will be launched and released to the Apple Store before the end of February, when customers can download the application directly. There are often customers here that AirLocate can't find our device, and they also cause self-righteous customers to give us a bad review. Explain that there are two possible reasons for this. 1.ariLocate bound uuid has no uuid that is not a device. The timeout interval is smaller than the broadcast interval of the device. The device defaults to 1s. You can set a shorter broadcast interval for the device.

     2. Some customers responded that the data displayed intermittently in the application of Apple software locate ibeacon.

The intermittent data is caused by the broadcast interval of the module. The detection interval of the locate ib software is relatively short. If there is no data in about 1s, no data will be displayed (two vertical bars). The module's default interval is 9S. Customers can use mobile phone configuration software to configure, the instruction is AT + ADVIX (X is a parameter from 0 to 9). The smaller the number is, the shorter the broadcast interval is. When the interval is 0, the interval is 100mS, so the mobile phone software can detect it faster. The application selects the appropriate value.

 

      3. Many customers believe that push messages are delivered through iBeacon base stations, but this is not the case.
       iBeacon only provides location services. The push message function requires you to develop an APP software and install it in the user's mobile phone, and mount the corresponding service program in the background. For example, users who entered the iBeacons broadcast range received a discount promotion message from the mall. The information was obtained by the application on the phone, not stored in iBeacons.
The specific implementation process is: After the APP software receives the location information broadcast by iBeacon, it performs a certain calculation to obtain its current location. When the calculated location meets the specific conditions you set, the APP requests a response from your advertising data server. The content is presented to the user, and then a message is pushed. In other words, to achieve dynamic information push, at least one APP software and one data server are needed. Of course, if only fixed content is presented to the user, a data server is not necessary.

    4. How to achieve the most power-saving state?

1. AT + UART1 instruction can be set to close the serial port. When HMSensor is in sleep mode

When the serial port function is automatically turned off
2.AT + ADVI instruction is configured in 0-F. The smaller the number, the smaller the broadcast interval, and the faster the mobile phone can read the data, but the smaller the broadcast interval, the more power it consumes, so you can set a longer time according to the needs of the project. Interval to save power.
3. AT + POWE provides 4 power modes, 0: -23db, 1: -6db, 2: 0db, 3: 6db, you can
Save power by setting lower power consumption based on project needs.
4.AT + KEYS1 instruction can save the power by turning off the key interrupt response during standby.
    iBeacons is a new feature of iOS7 that can be used for indoor near-field positioning. iOS devices can detect nearby iBeacons compatible devices.

    At present, the module is an official product. The firmware version number is V522. You can wirelessly query \\ to set the iBeacon Marjor value. You can wirelessly query \\ to set the iBeacon Minor value. You can set the broadcast interval. You can check the battery level wirelessly.
