Bluetooth 4.1 vs Bluetooth 4.0

1. Increase data transfer rate

Compared to Bluetooth 4.0, the Bluetooth 4.1 single packet data transfer maximum is increased from 20 bytes to 23 bytes, which increases the data transfer rate by 15%. According to this rule, you can try to modify the value of the single packet data payload. If the chip only supports BT4.0, then modifying the transmission of 23 bytes will either compile the error or drop the packet during the transmission.

2. Master and slave coexistence

The link layer link layer topology has been updated to allow simultaneous master-slave coexistence (time slice rotation) and a master-to-multiple slave connection topology.

3. Support 32-Bit UUID

32-Bit UUID refers to the UUID carried by the broadcast packet, not the 16-bit and 128-bit UUID that we refer to for the attribute list. The full 128-bit UUID can be obtained by broadcasting the 32-Bit UUID mapping so that the effective broadcast data length in the broadcast packet is more.
