When Touch operation is performed on the Touch control panel 22, the capacitance value on the Touch control panel 22 changes, and the Touch chip 21 generates a corresponding trigger instruction according to the capacitance change value on the Touch control panel 22 and transmits the trigger instruction to the bluetooth chip 1. The charger 6 is used for charging the battery 5, the battery 5 directly supplies power to the Bluetooth chip 1, and the power is respectively supplied to the Touch chip 21 and the functional module 8 through the low dropout regulator 7, so that when the TWS headset starts the Touch module 2 and/or the functional module 8, voltage noise can be effectively reduced, and user experience is improved. The microphone 3 and the loudspeaker 4 are respectively used for collecting sound and playing the sound, so that the TWS headset can realize the basic functions of a Bluetooth headset; the functional module 8 comprises a heart rate module, a step counting module and the like, and the functional module 8 enables the TWS headset to realize other functions besides the basic functions of the Bluetooth headset.
In this embodiment, the operation of continuously clicking the Touch control board 22 for four times in five seconds is set as one of the operations of controlling the corresponding earphone to enter the OTA upgrade mode, that is, after the user continuously clicks the Touch control board 22 on any earphone for four times in five seconds, the Touch chip 21 of the earphone sends an OTA upgrade mode trigger instruction to the bluetooth chip 1, so that the earphone enters the OTA upgrade mode. The operation of controlling the earphone to enter the OTA upgrade mode is not limited to clicking the Touch control board 22 four times, and other operations may be set as long as the user can be prevented from mistakenly triggering the earphone to enter the OTA upgrade mode.
After the main earphone and the slave earphone are started, the main earphone and the slave earphone are connected with each other, if the two earphones are successfully connected with each other, the main earphone and the Bluetooth equipment are connected with each other, and if the main earphone and the Bluetooth equipment are successfully connected, the Bluetooth equipment, the main earphone and the slave earphone are integrally connected with each other.
After a pair of TWS earphones is integrally connected with a bluetooth device, if OTA firmware upgrade is to be performed on the pair of TWS earphones, a user may first enter the OTA upgrade mode for both the master earphone and the slave earphone through any one of the following three steps (1), (2), and (3):
(1) the user can click the Touch control board 22 on the main earphone for four times within five seconds, then in the main earphone, the Touch chip 21 generates a trigger instruction for entering the OTA upgrading mode according to the capacitance variation on the Touch control board 22 and transmits the trigger instruction to the Bluetooth chip 1, the Bluetooth chip 2 enables the main earphone to enter the OTA upgrading mode after receiving the trigger instruction, after the main earphone enters the OTA upgrading mode, the main earphone sends an instruction for entering the OTA upgrading mode to the slave earphone connected with the main earphone, and the slave earphone also enters the OTA upgrading mode after receiving the instruction for entering the OTA upgrading mode.
(2) A user can continuously click the Touch control board 22 on the slave earphone for four times within five seconds, then in the slave earphone, the Touch chip 21 generates a trigger instruction for entering an OTA upgrading mode according to the capacitance variation on the Touch control board 22 and transmits the trigger instruction to the Bluetooth chip 1, and the Bluetooth chip 1 enables the slave earphone to enter the OTA upgrading mode after receiving the trigger instruction; after the slave earphone enters the OTA upgrading mode, the slave earphone sends an instruction for entering the OTA upgrading mode to the master earphone connected with the slave earphone, and the master earphone also enters the OTA upgrading mode after receiving the instruction for entering the OTA upgrading mode.
(3) A user can send an OTA upgrading mode entering instruction to a main earphone connected with the user through Bluetooth equipment, and the main earphone enters an OTA upgrading mode after receiving the OTA upgrading mode entering instruction; after the main earphone enters the OTA upgrading mode, the main earphone sends an instruction for entering the OTA upgrading mode to the connected auxiliary earphone, and the auxiliary earphone also enters the OTA upgrading mode after receiving the instruction for entering the OTA upgrading mode.
After the main earphone and the slave earphone all entered the OTA upgrade mode, because the main earphone, when the slave earphone and the Bluetooth equipment completed the integral connection, the Bluetooth equipment was connected with the main earphone through BLE, namely the Bluetooth equipment has established BLE channel connection with the main earphone through BLE, so the Bluetooth equipment only needs to establish SPP channel connection with the slave earphone through SPP again, can carry out the next step of OTA firmware upgrade: after the SPP channel connection is established, the Bluetooth device downloads the BIN files required by firmware upgrading through the OTA, sends the BIN files required by firmware upgrading to the master earphone through the BLE channel, and sends the BIN files required by firmware upgrading to the slave earphone through the SPP channel. Non-preferably, after the master earphone and the slave earphone both enter the OTA upgrade mode, the bluetooth device may establish an SPP channel connection with the master earphone through the SPP, and establish a BLE channel connection with the slave earphone through BLE, and then perform the next step of OTA firmware upgrade: after the SPP channel and the BLE channel are established, the Bluetooth device downloads the BIN files required by firmware upgrading through the OTA, sends the BIN files required by firmware upgrading to the master earphone through the SPP channel, and sends the BIN files required by firmware upgrading to the slave earphone through the BLE channel.
In the process of sending the BIN file by the Bluetooth equipment, the Bluetooth equipment can respectively control the speed of sending the BIN file by the BLE channel and the SPP channel by adjusting the size of a single data packet, so that the two channels can transmit the BIN file required by firmware upgrade at the same speed. After the transmission of the BIN file is completed, the Bluetooth device respectively sends a restarting instruction to the master earphone and the slave earphone, the two earphones are restarted after receiving the restarting instruction, and after the restarting, the firmware in the two earphones completes the process of covering the old BIN file with the new BIN file, so that the firmware program runs in the code area of the new BIN file, and the whole OTA firmware upgrading process of the TWS earphone is completed.
If the OTA firmware upgrade is to be performed on a single TWS earphone, the TWS earphone can use the BLE channel and the SPP channel to perform the OTA firmware upgrade after entering the OTA upgrade mode, and a user can control the channel connection between the TWS earphone and the Bluetooth equipment to be switched between the BLE channel and the SPP channel through software on the Bluetooth equipment.
