Example one
Please refer to fig. 1, which is a flowchart illustrating a method for reducing mutual interference between WIFI coexistence and BLE coexistence according to the present invention. As shown in fig. 1, the method for reducing mutual interference between WIFI and BLE coexistence includes the following steps:
firstly, executing step S1, and pre-adjusting the distribution positions of the WIFI antenna and the BLE antenna on the PCB, so that the WIFI antenna and the BLE antenna are separately placed along the edge of the PCB, and the directions of the WIFI antenna and the BLE antenna are mutually perpendicular;
for better understanding of step S1, please refer to fig. 2, which is a schematic diagram of the PCB after the distribution positions of the WIFI antenna and the BLE antenna on the PCB are adjusted in advance.
In this embodiment, in the pre-adjustment process, not only will make WIFI antenna and BLE antenna trend mutually perpendicular, still need to make the two physical separation keep as far as enough big as possible to guarantee that the two interval is enough big, avoid the interference between the two tentatively. Taking the length of the PCB board as 130mm and the width as 80mm as an example; after the pre-adjustment, the distribution position conditions of the WIFI antenna and the BLE antenna on the PCB are as follows: the distance from the right edge of the WIFI antenna to the right edge of the PCB is 54mm, and the distance from the center of the WIFI antenna to the right edge of the PCB is 63 mm; the distance between the upper edge of BLE antenna and the upper edge of PCB board is 18.6mm, and the distance between the center of BLE antenna and the upper edge of PCB board is 40mm, and is preferred, and the interval is 67mm between WIFI antenna and the BLE antenna.
Then, step S2 is executed, when WIFI and BLE work simultaneously, and the BLE communication state is detected to be deteriorated for the first time, the transmission power of WIFI is reduced to a predetermined value on the basis of ensuring normal communication of WIFI; wherein the basis for determining whether the BLE communication state is degraded is: whether the communication delay increases or the RSSI deteriorates.
Next, step S3 is executed, a second time of BLE communication state detection is performed, and if the BLE communication state is still deteriorated by the second time of BLE communication state detection, the WIFI and BLE time-sharing operation policy is started.
Specifically, please refer to fig. 3 and 4, fig. 3 is a flowchart of the WIFI and BLE time-sharing operating strategy; figure 4 is a schematic diagram of WIFI and BLE time sharing operating strategies. As shown in fig. 3 and 4, the WIFI and BLE time sharing operation strategy includes the following steps:
s30: acquiring the working states of BLE and WIFI;
s31: judging the priority of the working states of the WIFI and the BLE, and if one of the WIFI and the BLE is in a preparation working state, taking the part in the preparation working state as the part with higher priority; if both are in working state, taking BLE as the higher priority side;
furthermore, in the process of operating the party with the higher priority, the party with the lower priority suspends the data receiving and sending, and buffers all the received or to-be-sent data in the buffer.
S32: the party with high priority is operated firstly, and the party with low priority starts to operate after the operation of the party with high priority is finished.
For better understanding of the WIFI and BLE time sharing operation strategies, the following is detailed with an example:
as shown in fig. 4, communication is established between the WIFI module and the BLE module through two GPIO lines, specifically including a GPIO-WIFI-TO-BLE line for acquiring a working state of WIFI and a GPIO-BLE-TO-WIFI line for acquiring a working state of BLE; MCU is used for controlling WIFI's transmitting power, controlling whether communication and the communication state of detection BLE of BLE are whether BLE and WIFI communicate. If the current BLE is acquired to be in a preparation working state (namely, a working state is required), the BLE module informs the working state of the WIFI module based on the GPIO line, the WIFI module is required to pause transceiving, all data are cached in a buffer, when the BLE module does not work, the WIFI module is informed of no work of the BLE module based on the GPIO line, the WIFI can cancel the pause, and data transceiving is started. Otherwise, it is not described herein in detail.
