সেন্টার মোড এবং ব্লাডের পেরিফেরিয়াল মোডের মধ্যে পার্থক্য
Wireless communication has become an invisible bridge in the Internet of Things connection, এবং ব্লুটুথ, as a mainstream wireless communication technology, plays a vital role in the Internet of Things application. we receive inquiries from customers about the Bluetooth module sometimes, but during the communication process, I found that some engineers are still vague about the concept of the Bluetooth module 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, দাস, 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; Bluetooth module communication refers to the communication between two Bluetooth modules 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. এই মোডে, you can search for surrounding devices and select the slave devices that need to be connected for connection. তত্ত্ব, একটি ব্লুটুথ মাস্টার ডিভাইস এর সাথে যোগাযোগ করতে পারে 7 একই সময়ে ব্লুটুথ স্লেভ ডিভাইস. A device with Bluetooth communication function can switch between the two roles. এটি সাধারণত স্লেভ মোডে কাজ করে এবং অন্যান্য মাস্টার ডিভাইসগুলির সংযোগের জন্য অপেক্ষা করে. When needed, এটি মাস্টার মোডে স্যুইচ করে এবং অন্যান্য ডিভাইসে কল শুরু করে. When a Bluetooth device initiates a call in the main mode, এটি অন্য পক্ষের ব্লুটুথ ঠিকানাটি জানতে হবে, পাসওয়ার্ড জুড়ি, এবং অন্যান্য তথ্য. জোড় শেষ হওয়ার পরে সম্পূর্ণ, কলটি সরাসরি শুরু করা যেতে পারে.

Slave device mode: The Bluetooth module working in slave mode can only be searched by the host, and cannot be actively searched. After the slave device is connected to the host, it can also send and receive data with the host device.
