Discovery process time delay optimization method of bluetooth device

[0019] In order to describe in more detail the Bluetooth device discovery process delay optimization method proposed by the present invention, in conjunction with the accompanying drawings, an example is as follows:

[0020] Step 1: Build a network environment, define master and slave devices, set the number of master devices to 1, and the number of slave devices to n. When the device discovery process starts, the master device is in the query state, and the slave device is in the query scan state;

[0021] The second step: if Figure 4 As shown, change the query mode of the master device, and change the original query in sequence A and B for 256 times and then turn to another sequence mode to change the query mode of the master device to 256 times at 32 query frequencies in sequence; the third step: from The device listens to the ID packets from the master device on the same 32 frequencies, and enters the random backward delay stage after listening;

[0022] Step 4: After the
