Perbezaan Antara Mod Tengah dan Mod Pinggiran BLE

Wireless communication has become an invisible bridge in the Internet of Things connection, dan Bluetooth, as a mainstream komunikasi tanpa wayar teknologi, plays a vital role in the Internet of Things application. we receive inquiries from customers about the Modul Bluetooth sometimes, but during the communication process, I found that some engineers are still vague about the concept of the Modul Bluetooth as the master and slave, but we have a strong curiosity about technology, how can we tolerate the existence of such knowledge What about blind spots?

BLE peripheral “Slave”

Generally we call BLE Center “Master mode”, call BLE peripheral “Slave”.

BLE has the following roles: Advertiser, Scanner, Hamba, Master, and Initiator, where the master is converted by the initiator and the scanner On the other hand, the slave device is converted by the broadcaster; Modul Bluetooth communication refers to the communication between two Modul Bluetooth or Bluetooth devices. The two parties for data communication are the master and the slave

Master device mode: It works in master device mode and can connect with a slave device. Dalam mod ini, you can search for surrounding devices and select the slave devices that need to be connected for connection. In theory, one Bluetooth master device can communicate with 7 Bluetooth slave devices at the same time. A device with Bluetooth communication function can switch between the two roles. It usually works in slave mode and waits for other master devices to connect. When needed, it switches to master mode and initiates calls to other devices. When a Bluetooth device initiates a call in the main mode, it needs to know the other party’s Bluetooth address, kata laluan berpasangan, dan maklumat lain. Selepas berpasangan selesai, panggilan boleh dimulakan secara langsung.

Mod peranti hamba: Modul Bluetooth yang berfungsi dalam mod hamba hanya boleh dicari oleh hos, dan tidak boleh dicari secara aktif. Selepas peranti hamba disambungkan ke tuan rumah, Ia juga boleh menghantar dan menerima data dengan peranti tuan rumah.
