In a specific embodiment, referring to fig. 6, fig. 6 describes a combined communication processing flow of RFID and bluetooth BLE, and after the RFID probe card is successful, corresponding processing is performed according to the current working state of bluetooth BLE.
1. When a single MCU chip is used, the RFID can periodically start the operation of the probe card, and the Bluetooth BLE can periodically send advertisement data. The operation of the probe card is generally completed by the hardware of the radio frequency module, and software intervention is not needed, so that MCU work is not needed to be started; the bluetooth BLE advertisement data transmission needs software control to be completed, so that the MCU needs to be started to work normally.
2. And once the RFID is successful in detecting the card, the MCU is instructed to start working. Since RFID and bluetooth BLE are two devices that operate in parallel, the MCU may already be starting communication operation that is processing BLE, so starting the MCU here is just a process that actually may not need to actually start the MCU hardware operation.

3. And detecting the working state of the RFID. And if the RFID is currently in the communication process, waiting for the completion of the RFID communication.
4. And starting Bluetooth to perform communication operation.
In a particular embodiment, referring to fig. 11, fig. 11 depicts a timing diagram of bluetooth BLE periodic advertisement events and RFID communication processing. Because bluetooth BLE advertisement event is periodically going on, still there is certain interval of time between the advertisement data package that every advertisement event inside sent, the rfid can make full use of these space time normal completion communication process to can not produce great communication delay.
In a particular embodiment, referring to fig. 12, a timing diagram of bluetooth BLE connection events and RFID communication processing is depicted in fig. 12. CE in the figure is an abbreviation of Connection Event, and CE len represents the communication time length of one BLE Connection Event. Because the BLE connection events are periodic, a certain time interval exists in the communication between the devices, and the RFID can fully utilize the idle time between the connection events to complete the communication process. For the situation that the CE len occupies the whole BLE connection event, because the RFID is guaranteed to normally complete communication preferentially, the RFID communication can be completed preferentially within the timeout time of Bluetooth Supervision Timeout if necessary, and then the Bluetooth connection event is processed, and the actual influence on the Bluetooth connection communication is smaller.
In fact, the above-described communication control method and system can be applied to a fingerprint and BLE combined communication system, a cipher key and BLE combined communication system, and the like, in addition to the combined communication of RFID and bluetooth BLE, and will not be described in detail.
