The Bluetooth protocol used by the Bluetooth scanner

With the widespread use of Bluetooth scanners, how to choose the Bluetooth module used on the scanner, among which the protocol supported by the Bluetooth module is an important selection criterion. So this article lets us understand the protocols supported by the Bluetooth module used on the scanner and the advantages and disadvantages of each protocol.

The Bluetooth protocol used by the Bluetooth scanner
  • HID (Human Interface Device)

advantage:

1. You can directly input in the text box, no additional software is required.

2. Good compatibility, supported by Android, IOS, Windows, Linux and smart devices based on Android or Linux.

shortcoming:

1. Small amount of data

  • SPP (Serial Port Profile)

advantage:

1. Large amount of data

2. Stable transmission

shortcoming:

1. Requires software cooperation

2. IOS devices need to pass MFI to use

  • GATT (Generic Attributes)/BLE

advantage;

1. The amount of data is larger than that of HID

2. Stable data transmission

3. Android, IOS, Windows, Linux and other hardware can support BLE

shortcoming:

1. Requires software cooperation

  • HOG (HID Over GATT)

advantage:

1. You can directly input in the text box, no additional software is required

2. Android, IOS, Windows, Linux and other hardware can support BLE

shortcoming:

  1. Small amount of data
