Bluetooth can not transmit data
Solutions:
1. For Bluetooth file sharing and sending, first confirm that the two devices have paired up; In the case of unpaired connection, it is necessary to ensure that the Bluetooth of both parties is on and in the state of open detection/detectability/visibility of the mobile phone. For example, the computer must be on the interface of "receiving file" before pairing connection.
2. In the process of file transfer, if the distance between two devices exceeds the effective transmission distance of Bluetooth (10 meters), the transmission will fail. It is suggested to try again within the effective distance.
3. When sending files to other Bluetooth devices, if the other party fails to respond for a long time, the sending will be terminated. Please remind the other party to receive the files timely after sending,
4. Not all file formats can be transmitted by Bluetooth (for example, APK can not be transmitted). After repeated reminders, it is advised to change the file suffix to. Mp3 /. TXT formats.
5. If the Bluetooth of the other device does not support the file type sent by the receiving one, the file will not be transmitted. Please confirm the file type supported by the other device before transmission.
6. If the transfer file is abnormal or too large, the mobile phone does not have enough memory to store or the transfer time is too long, which may cause the file sending failure. Files can be divided into small file transfers.
7. If it is connected to 2.4G WiFi, the same frequency interference may occur due to the Bluetooth working in 2.4G band, it is suggested to turn off WiFi and try again; If mobile phones and wireless routers support 5G WiFi, it is suggested to change to 5G band.
8. If there is a magnetic field nearby that interferes with Bluetooth connection, such as around the iron magnetic field, it is suggested to change the environment.
9. If the change of environment cannot be solved, it is recommended to compare the connection between the mobile phone and other mobile phones, and observe whether the Bluetooth will still be disconnected automatically and the data can not be transmitted, and check whether it is the mobile phone.
10. Restore the factory Settings after backing up the mobile phone data (phone number, SMS and photo, etc.) and check whether it is caused by system abnormality.
11. Due to low efficiency of Bluetooth transmission and inferior compatibility to other file transmission schemes, if there is the need of file transmission, it is recommended to use LAN, OTG and other methods for transmission. If there is a strong need to use Bluetooth transmission and none of the above methods can solve the problem, bring the mobile phone to the nearest MI after-sales service center for inspection and processing.
