Things You Need To Know For Bluetooth Modules:

1 What is Bluetooth 4.0:
 Bluetooth 4.0 is consists of Bluetooth Basic Rate (BR)/Enhanced Data Rate (EDR), High Speed (HS) and Low Energy (LE), Bluetooth 4.0 covers the Bluetooth 2.0,2.1,3.0 Versions. Nowadays, there are a lot of devices powered by Bluetooth 4.0, such as Bluetooth Earphone, Speakers, Vehicle Electronic Equipment, OBD, Printer, Barcode Scanner, Mobile Medical Device, Bracelet, Pedometer, etc.

2 What is Bluetooth Dual Mode Module:
 Bluetooth Dual Mode Module is a Single-Module Bluetooth Solution with Built-in Bluetooth Basic Rate (BR)/Enhanced Data Rate (EDR)/Low Energy (LE) Functions.

3 What is BLE Module:
 BLE Module is a Single-Module Bluetooth Solution with Built-in Bluetooth Low Energy (LE) Function.

4 What are the Bluetooth Dual Mode Advantages:
 There are two most frequently applied Bluetooth Profiles for the general data communication between Smart Device and Bluetooth Peripheral: BLE and SPP.

In iOS, SPP is Only Available after the Bluetooth Peripheral passed the MFi Certification, in view of the high cost and complex process of the MFi Certification, BLE is much good to use. In Android Camp, BLE is Only supported by Android 4.3 and later versions of the Android OS, this lead to the serious system fragmentation issues and make a lot of Android devices has the bad compatibility for the BLE, so SPP has a huge advantage for data communication in android.

In Summary, If one product need to support iOS and Android devices simultaneously, our Bluetooth dual mode modules are the best choice.

5 What is the transmission distance for Bluetooth Modules:
 Class 2 : 10M Class 1: 100M

6 What is the transmission speed For Classic Bluetooth Module SPP & BLE 4.0
 Under Ideal Condition:
 SPP: About 80KBytes/s
 BLE: About 8KBytes/s

(Remarks: When starts the audio transmission ,the transmission speed for both types will be decreased. When music on, BLE transmission speed is about 1~2KBytes/s )
