Step S11: and acquiring a radio frequency signal received by a Bluetooth module of the debugging terminal in the process of Bluetooth communication between the debugging terminal and the testing equipment.
Wherein the debug terminal includes, but is not limited to, a debug PC (i.e. Personal Computer, personal computer), the test equipment includes, but is not limited to, a Bluetooth headset, etc.

That is, the bluetooth Protocol stack in the present application includes a controller layer and a host layer, where the controller layer includes an underlying BB (i.e., baseband), LMP (i.e., LINK MANAGER Protocol, link management Protocol), RF (i.e., radio Frequency), AVDTP (AUDIO/VIDEO DIST RIBUTION TRANSPORT PROTOCOL ), AVRCP (i.e., AUDIO vidoe remote control Protocol, AUDIO/video control transport Protocol), L2CAP (i.e., the Logical Link Control and Adaptation Layer Protocol, logical connection control and adaptation Protocol), ACL (i.e., asynchronousConnectionless, asynchronous connectionless link), SCO (i.e., synchronous Connection Oriented, facing synchronous connection). Host layers including GAP (i.e., GENERIC ACCESS Profile universal access application specification), SDP (i.e., service Discovery Protocol, service discovery Protocol), SDAP (Service Discovery Application Profile, service discovery application specification), OPP (i.e., object Push Profile, object storage specification), FTP (i.e., FILE TRANSFER Protocol, file transfer Protocol), A2DP (i.e., advanced Audio Distribution Profile, bluetooth audio transfer model Protocol audio link), HFP (i.e., hands-free Profile, telephone link). The embodiment of the application records the analysis data corresponding to each protocol or specification, thereby realizing the communication quality analysis.

It should be noted that the protocols and specifications in fig. 4 are only exemplary of a portion of the protocols in the controller layer and the host layer, where RFCOMM is a serial linear emulation protocol. In one embodiment, the baseband and the resolution data corresponding to the LMP may be directly obtained by reading the bluetooth module, and other protocols and specifications of the bluetooth protocol stack may be implemented by writing software.
In a specific embodiment, the target controller layer analysis data may be put into the shared memory first; correspondingly, reading the target controller layer analysis data from the shared memory through a preset virtual HCI interface, and sending the target controller layer analysis data to the host layer.

Bluetooth communication is based on cid implementation. If no abnormality exists, the MTU (i.e. Max Transmit Unit, the maximum transmission unit) is detected, and when the data packet sent by the application layer is too long, the data packet is split according to the MTU. And then, judging whether the channel of the current Bluetooth module is crowded or not by checking a L2CAP- > cong _send field, and if so, returning abnormal information, for example, the abnormal information is defined as L2CAP_CH_FAILED. The embodiment of the application can judge whether the current Channel is crowded or not based on the condition of the crowding of the current Channel when the data of the Bluetooth module bottom layer is read, and assign a value to the l2cap- > cong _send field based on the condition of the crowding of the current Channel, so that the field can be read when the data is issued, and whether the current Channel is crowded or not is judged. If not, the data can be sent, the data is sent to the controller layer through the L2CAP_ DATAWRITE function, and the data is directly interacted with computer hardware through the controller layer). Entering the L2cap_ DATAWRITE function marks that the data has been successfully delivered to the L2CAP for processing, and has no relation to the upper layers. After the running of the L2CAP_ DATAWRITE function is finished. The l2cap- > cong _send field is checked again to see if the data was sent successfully. If l2cap- > cong _send is l2cap_ch_ CONGESTED, then l2cap_ch_ CONGESTED is returned, indicating that the current channel is congested, and if l2cap- > cong _send is l2cap_ch_success, l2cap_ch_success is returned, indicating that the data has been successfully transmitted. It should be noted that after the bluetooth module successfully sends out the radio frequency signal, the corresponding signal successful sending information is returned, and the embodiment of the application can assign a value to the l2cap- > cong _send field based on the signal successful sending information.
Further, referring to fig. 6, fig. 6 is a schematic diagram of a software state machine according to an embodiment of the present application, that is, the following states may be defined for the bluetooth communication detection software: CLOSED state (off state), representing an event in which BT Channel is in CLOSED state. This state exists only during Link initial setup of the L2 CAP. Assuming that the L2CAP_CH_DISCONNECT_IND returned by the bottom layer is received, the current Link has been disconnected. The ccb of the current Channel needs to be released. In the open state, if the event is l2cap_ch_connect_cfm, the connection is established, the configuration is completed, and the data stream is being transmitted. That is, embodiments of the present application represent the current communication state by an event. The configuration state, the state machine that the configuration state has realized is as follows: wait_config (i.e., WAIT for configuration), wait_send_config (i.e., SEND configuration WAIT), wait_config_req_rsp (i.e., request for WAIT for acknowledgement), wait_config_rsp (i.e., configure WAIT for acknowledgement), wait_config_req (i.e., configure request), wait_control_ind (i.e., configure CONTROL field). Waiting for a broken link state: when CloseChannelReq (i.e., a close channel request) is received, the wait_disconnect state is entered from the configure state.
