In general, when a finished product passes BQB certification, the test will be divided into two parts, one part is the RF test of the circuit board, and the other part is the profile test of the whole machine. The profile test of the whole machine is to test the functions supported by Bluetooth when the product is actually used. Different products have different Bluetooth functions, and the supported profiles are also different.
Next, let's take a look at the profiles that need to be tested generally supported by common Bluetooth products on the market
1. Headphones and speakers
This type of product generally has the role of A2DP (Advanced Audio Distribution Profile) sink, and the prototype can receive the audio transmitted from the audio source. RCP (Audio Video Remote Control Profile) CT (Controller) and TG (Target) roles, test and control functions such as pausing, up and down, volume up and down, etc. The HF (Hands-Free) role of HFP (Hands-Free Profile) can be used to test call-related functions such as the pick-and-connect of the prototype.
Second, mobile phone tablet projector class with intelligent operating system:
This kind of product belongs to the audio source category, and generally supports:
1) A2DP (Advanced Audio Distribution Profile) source role to test whether the function of transmitting audio from the prototype to the sink terminal is complete.
2) The TG role of RCP is used to verify that the prototype can perform various operations on ** in the APP.
3) OPP (Object Push Profile) Object Push Server role, the test prototype can receive files through Bluetooth.
4) If the product can insert **card to call**SMS, then it will also be supported.
5) PBAP (Phone Book Access Profile) to test the functions related to the ** book.
6) HFP (Hands-Free) AG role (Audio Gateway), test the call function of the prototype dialing **.
7) MAP (Message Access Profile), which tests the function of the product to send and receive SMS.
Three, remote control, locator, Bluetooth keyboard and other common products that support Bluetooth Low Energy:
Depending on the function settings of these products, the following may be supported:
1) BAS (Battery Service) to verify the battery service function in Bluetooth products.
2) dis (device information service) to verify the function of the device information service in the Bluetooth host.
3) HIDS (HID Service) to verify the function of the HID service in the Bluetooth host.
