 +
 +===== Principle of operation =====
 +
 +The BLE radio tag is installed on the trailed equipment and
 +has an internal power supply. Every 5 seconds, the tag transmits via
 +Bluetooth its unique ID. The BLE radio module installed on the
 +tractor/tractor is always in reception mode. As soon as
 +the radio module receives the tag's Bluetooth ID, it starts broadcasting
 +it to the CONNECT-BUS, and on request it can also transmit it via
 +RS485. When exchanging data between the master device and the BLE
 +radio module via RS485, the SOVA protocol is used. Transmission of the tag ID
 +is transmitted within a specified timeout (available for configuration).
 +
 +The radio module can simultaneously receive signals of 8 tags. В
 +CONNECT-BUS transmits the tag ID and the level of its signal reception.
 +PGN 18F701 - 18F708 are used. The first byte in the PGN
 +is the tag validity status (used by the RL module to
 +The first byte is the tag validity status (used by the RL module to enable the relay). The second byte is the signal reception level
 +(RSSI, unit dBm). The next 6 bytes - the tag ID.
 +
 +Please note that when working via RS485 only 5 bytes of the tag ID are transmitted
 +bytes of the ID tag, without the high byte. This is due to limitations
 +of the SOVA protocol.
 +
 +Depending on the level of signal reception the tag parameters
 +are transmitted to the CONNECT-BUS as follows: In the PGN 18F701
 +the parameters of the tag that is as close as possible to the
 +to the radio module (has the highest signal level). IN PGN 18F702
 +8
 +the parameters of the tag with a weaker signal are transmitted, etc. IN PGN
 +18F708 transmits the parameters of the tag with the weakest signal.
 +
 +The main variable to determine the current tag is
 +variable "priority tag ID". In this variable the ID
 +of the tag that is closest to the reader is passed in this variable. In this case, if
 +to the reader is temporarily close to another tag, then
 +tags will switch only after the timeout specified in
 +parameter ID0210 - "Timeout of holding the priority tag during its
 +change". The same variable is transmitted via RS485.
 +
 +The system has the ability to transmit an arbitrary number
 +up to two bytes in size other than the tag ID. To implement this function
 +you need to write arbitrary numbers to the tags, if necessary.
 +
 +----
 +
 +===== Configuring Label Groups =====
 +
 +Labels are customizable. For each label you can
 +set up:
 +  * the group it belongs to;
 +  * an arbitrary number that will be transmitted by the tag along with its own ID.
 +
 +The tag ID cannot be changed.
 +
 +For each tag it is possible to set the group to which it belongs.
 +it belongs to. Each tag can belong to only one
 +group, while the reader can simultaneously work with 5
 +groups of tags.
 +
 +For example, if at one company the system
 +is used as part of a "friend-or-foe" system to monitor the
 +unloading the combine and in the same company the system is used to identify the towed implements.
 +used to identify trailed implements, there is no need for readers installed at the same location.
 +There's no need for the readers on the harvesters to
 +interact with the tags installed on the trailed units.
 +For this purpose, the working group names of the tags can be different.
 +
 +The BL reader will only read the tags whose groups
 +which are prescribed in the reader settings.
 +By default, all tags belong to the group BITREK. In the settings
 +of the readers by default also prescribed only one group -.
 +BITREK.
 +
 +The procedure of setting the tag groups for the readers is similar to
 +setting of any other parameters of the reader. To configure
 +the Connect Configurator program is used. Since the BL reader
 +is a module of the Bitrek Connect system, the principle of configuring this
 +module is the same as the other modules of the system. A description of the principle
 +The configuration principle is described in the document Connect General Manual.
 +
 +
 +The tags are configured with a special programmer for BLE
 +RFID tags are configured by a special programmer for BLE tags. The following is a step-by-step procedure for configuring the tags.
 +  - Disconnect power element of the tag.
 +  - Connect the box to your PC.
 +  - Launch COM Sender software. Select COM port the programmer is connected to. Press the "Close Port" button.
 +  - Enter the following commands into the program:\
 +    - setparam 0910 GROUP1;\\
 +    - setparam 0210 1234;\
 +    - saveparam;\
 +    - where,{\
 +    - GROUP1 is the name of the group the tag belongs to;\
 +    - 1234 is an arbitrary number (if necessary)
 +    - Sending the saveparam command is mandatory.
 +  - Connect the programmer to the tag.
 +  - Press "Open port" button.
 +  - Press 'Send' button. After that the commands will be sent to the device.
 +  - Click the "Close Port" button.
 +  - Disconnect the programmer from the tag.
 +  - Connect the battery.
 +
 +This completes the tag setup.
