Bluetooth BLE Throughput
Bluetooth BLE is just a subset of the Bluetooth protocol, which belongs to the Bluetooth low energy part. This is basically a new technology that only exists after Bluetooth 4.0, and it has been launched for almost 10 years.
Bluetooth BLE focuses on data transmission, such as common applications such as: Xiaomi Bluetooth bracelet, Apple’s airtag anti-lost device, etc.
The transparent transmission of Bluetooth BLE is actually a part of the application of Bluetooth transparent transmission. Because of the existence of IOS, it is basically necessary to use Bluetooth BLE to connect with IOS devices.
As for the description of transparent transmission, it is consistent with the concept of “Bluetooth transparent transmission” mentioned above
In other words, “Bluetooth BLE transparent transmission” is a subset of “Bluetooth transparent transmission”
At present, Bluetooth BLE will be the mainstream in the future, and with the continuous upgrade of the Bluetooth protocol version, it will also receive a large program of technical upgrades, such as the latest LE audio is also based on the underlying technology of BLE
Bluetooth SPP Throughput
Bluetooth SPP is also a subset of the Bluetooth protocol, but it is different from BLE. The existence of SPP has existed in the early days of the Bluetooth protocol. The earliest Bluetooth protocol version 1.0 contains the SPP part.
Bluetooth SPP is a subset of classic Bluetooth. The classic Bluetooth is a subset of the Bluetooth protocol. They are such an affiliation
It has been 20 years since the launch of Bluetooth SPP, and the application scenarios are also very extensive, but basically most of the applications are slowly being replaced by BLE. After all, the future development trend of the Bluetooth protocol is BLE. The application of classic Bluetooth will gradually withdraw from the stage of history
The most typical product of Bluetooth SPP is the HC-05 module, which is so famous. I don’t know if the person who designed this module remembers what it was designed for and whether it would bring such a It is widely used, and the design is indeed good, but this has a historical reason, that is, there is no choice, only CSR is a choice.MuYu launched a Bluetooth module that replaces HC-05——MY-BT102. This module can completely replace HC-05 and has more perfect functions.
The transparent transmission of Bluetooth SPP is also a part of the application of Bluetooth transparent transmission. Because of the existence of IOS, basically it is necessary to use Bluetooth BLE to connect with IOS devices. However, due to historical reasons on the Android side, many applications still use the traditional SPP. I don’t know why many manufacturers are unwilling to change it.
For example: Bluetooth printers, access control, etc., are still SPP. In fact, it can be changed to ble, which is no problem.
