Smartphone Honor 10, released in 2018, has long remained a flagship device thanks to its powerful Kirin 970 processor and high-quality camera. However, over time, users encounter difficulties connecting modern wireless accessories: new headphones, smart watches or car multimedia systems. Bluetooth protocol version is a critical parameter that determines the data transfer speed, range and energy efficiency of the connection. If your device does not see a new gadget or the connection is constantly interrupted, the reason may lie precisely in the incompatibility of standards versions.
Many owners mistakenly believe that this information is easy to find in the standard settings menu, but the EMUI shell interface often hides technical details from the average user. In this article, we will look at all the available methods - from simply viewing specifications to using engineering codes and USB debugging. You'll learn how to accurately determine whether yours supports modern codecs/aptX and why this is important for sound quality. Understanding the technical specifications of your smartphone will help you avoid wasting money on incompatible accessories. Next, we will look in detail at diagnostic methods and interpretation of the data obtained. Honor 10 modern codecs/aptX and why it is important for sound quality.
Understanding the technical characteristics of your smartphone will help you avoid unnecessary expenses on purchasing incompatible accessories. Next, we will consider in detail the diagnostic methods and interpretation of the data obtained.
Official specifications and basic information
Before delving into the technical jungle and using complex tools, it is worth turning to the official data of the manufacturer. The company Huawei, which owns the Honor brand, clearly regulates the technical characteristics of its devices at the time of entering the market. The model Honor 10 declared support for the standard Bluetooth 4.2 with additional profiles for transferring audio and files.
This version of the protocol was relevant at the time of release, providing a stable connection at distances of up to 10 meters in line of sight. However, it is inferior to newer standards such as Bluetooth 5.0 or 5.2, which appeared in subsequent generations of smartphones. The difference lies not only in speed, but also in the ability to connect multiple devices simultaneously without losing signal quality.
⚠️ Attention: Official specifications may not reflect actual capabilities after updating drivers or modifying the system, but they are a basic reference point.
To check basic information through the interface, go to menu Settings → System → About phone. Here you will find the processor model and Android version, but the specific Bluetooth version number is often missing. This is done intentionally so as not to overload the interface with unnecessary data for the average user.
Nevertheless, knowing that the Kirin 970 hardware platform is physically limited to supporting Bluetooth 4.2, you can immediately dismiss doubts about the availability of newer versions. Software updates can fix security bugs, but they cannot change the physical capabilities of the radio.
If you are planning to buy new wireless headphones that support LDAC or aptX HD, make sure they are backwards compatible with Bluetooth 4.2, otherwise the sound quality will be limited by the standard SBC codec.
Using applications for detailed diagnostics
The most accessible way to get accurate information about the capabilities of the radio module is to install specialized utilities from the store Google Play. There are many free applications that read data directly from the system and display it in an understandable way. One of the most reliable tools is considered to be an application Bluetooth Info or analogues like Device Info HW.
After installing and launching the app, you need to give it permission to access the location and Bluetooth adapter. This is a mandatory requirement of the operating system Androidas scanning the airspace can theoretically be used to track the user. After granting rights, the application will show a detailed list of supported profiles and the stack version.
- 📱 Bluetooth Info —shows the LMP (Link Manager Protocol) version, which directly correlates with the Bluetooth version.
- ⚙️ Device Info HW —provides comprehensive information about all hardware, including radio module details.
- 🔍 AIDA64 —a popular system monitor that displays the Bluetooth version in the "Network" section or "Devices".
Pay attention to the parameter LMP Ver. In diagnostic utilities, the Bluetooth version is often encoded specifically through the version of the connection manager. For Honor 10 you will see the value corresponding to the 4.2 specification. If an application shows the version number of the kernel or stack, it can be deciphered using special correspondence tables.
It is important to understand that third-party applications read the data that the operating system provides them. If the manufacturer has blocked access to certain system calls in the EMUI shell, the application may show general information or request root access. In most cases, standard access is sufficient for Honor 10.
Checking through the engineering menu and system logs
For more advanced users who do not want to install unnecessary software, there is a method of checking through system logs or the engineering menu. This method requires care, since changing settings in the engineering menu can affect the operation of the radio modules. We'll look at a safe method for viewing logs without making changes.
Open the Phone app and enter a special code to access device information. Honor and Huawei smartphones often run code ##2846579##that opens the project menu. However, to view detailed Bluetooth logs, it is more convenient to use the built-in debugging function or third-party loggers if the menu is closed.
⚠️ Attention: Do not change the settings in the engineering menu if you are not sure of their purpose. Resetting the antenna calibration may result in poor signal reception.
An alternative method is to use the "For Developers" section. Activate it by going to Settings → System → About phone and clicking 7 times on the build number. Then, in the developer menu, enable USB debugging and look for "Bluetooth Error Log" or similar. There you can see a detailed connection log, where the protocol version is often mentioned when handshake (handshake) with the device.
You can also use the command via ADB (Android Debug Bridge) by connecting the phone to the computer. This is the most accurate method and requires installing drivers on the PC. The command allows you to request information about the properties of the Bluetooth controller directly.
adb shell getprop | grep bluetoothThis command will display a list of system properties related to bluetooth. Look for lines containing the firmware version or vendor ID. Although a direct version number may not be displayed, the chip ID will allow you to accurately determine its capabilities through a search in the Broadcom or Huawei database.
What is an LMP version?
LMP (Link Manager Protocol) is a protocol that controls the establishment of communications between devices. The LMP version number clearly indicates the Bluetooth version: LMP 8 corresponds to Bluetooth 4.2, LMP 9 corresponds to Bluetooth 5.0, and so on.
Analysis of compatibility and connection profiles
Knowing the Bluetooth version is only half the battle. For comfortable use, it is important to understand which profiles your Honor 10supports. Even with the same version 4.2, different smartphones may support different sets of codecs and data transfer profiles, which directly affects the user experience.
For example, for listening to music, support for the profile A2DP (Advanced Audio Distribution Profile) is critical. It is he who is responsible for transmitting high quality stereo sound. If your smartphone and headphones support different codecs within this profile (for example, only SBC vs aptX), the sound will be transmitted in compressed form with loss of detail.
| Profile | Purpose | Support for Honor 10 |
|---|---|---|
HFP |
Speakerphone (calls) | ✅ Full |
A2DP |
Stereo audio transmission | ✅ Full (SBC, AAC) |
AVRCP |
Player control | ✅ Full |
MAP |
Messaging | ⚠️ Partial |
The table above shows the main profiles. Honor 10 copes well with basic tasks: calls and music via AAC or SBC. However, support for advanced codecs, such as aptX HD or LDAC, is not available in hardware in this model, since they require newer versions of chipsets or licensing, which Huawei has not implemented in this generation.
When connecting a car radio or smart bracelet, nuances may arise with the profile PAN (Personal Area Network) for Internet distribution or HID (Human Interface Device) for connecting keyboards. In most cases, Honor 10 correctly detects these devices, but if it fails, it’s worth checking whether the profile is disabled in the developer settings.
The lack of aptX support on Honor 10 does not mean poor sound quality - the AAC codec, when used with an iPhone or high-quality Android headphones, provides excellent sound.
Solving problems with connection and visibility
If you have checked the Bluetooth version and are convinced of compatibility, but the devices still do not pair, the problem may lie in a software glitch or Bluetooth service cache. The operating system Android over time accumulates errors in communication services, especially after multiple connections of different gadgets.
The first step should always be clearing the Bluetooth cache. To do this, go to Settings → Applications → Show system processes. Find "Bluetooth" in the list, go to the "Memory" section and click the "Clear cache" button. This action will not delete paired devices, but will reset temporary service files.
- 🔄 Reboot - a banal but effective method of restarting all radio modules.
- 🗑️ Deleting a pair — remove the device from the list of paired devices on both gadgets and try connecting again.
- 📶 Airplane mode —turn on airplane mode for 10 seconds, then turn it off to completely re-register on the network.
In some cases, resetting the network settings helps. This operation is more radical: it will delete all saved Wi-Fi passwords and Bluetooth settings, but return the network modules to their factory state. Path to this function: Settings → System → Reset → Reset network settings.
⚠️ Attention: Before resetting network settings, make sure you remember the passwords for important Wi-Fi networks, as you will have to enter them again.
If problems arise with a specific device type (for example, only with a watch), try updating the firmware of the peripheral device itself. Accessory manufacturers often release updates that improve compatibility with older versions of Android and Bluetooth.
☑️ Diagnosing connection problems
Impact of Android version and security updates
Don't forget that software plays no less a role than hardware. Honor 10 was originally released on Android 8.0, but received an update to Android 9.0 and 10 depending on the region and version of the EMUI shell. With each security update, Google and Huawei make changes to the Bluetooth stack, closing vulnerabilities and improving stability.
Sometimes after a major update, users notice that some older devices stop connecting. This is due to stricter requirements for connection encryption. For example, security protocols that were considered normal several years ago may now be blocked by the system as unsafe.
You can check the current build version in the menu About the phone. If an update is available, it is recommended that you install it, as patches often contain fixes for wireless drivers. However, it is worth considering that on older devices, new versions of Android may work slower.
Why did the sound disappear after the update?
Often, after updating Android, codec settings are reset to default. Go to the developer settings and force select the SBC or AAC codec if the automatic selection does not work.
There is also a nuance with regional firmware versions. The global version (Global ROM) and the Chinese version (CN ROM) may have different sets of certified frequencies and profiles. If you have flashed your phone, make sure that the radio module works correctly with your region.
Frequently asked questions (FAQ)
Is it possible to update Bluetooth on Honor 10 to version 5.0 software?
No, it is not possible. The Bluetooth version is determined by a hardware chip (radio module) soldered on the motherboard. Software updates can only optimize the operation of the existing module, but not add support for new physical standards.
Why does Honor 10 not see new headphones, although they are working?
The headphones may be in pairing mode with another device or use a protocol that is incompatible with Bluetooth 4.2. Try resetting the headphones to factory settings and make sure they are in visibility mode (flashing indicator).
Does the case affect Bluetooth operation?
Yes, thick cases with metal inserts or magnetic clasps can shield the signal from the antenna, which in Honor 10 is located at the top of the case. To check, remove the case and try connecting again.
How to improve sound quality when connected via Bluetooth?
Enable the "Disable absolute volume level" option in the developer settings or try changing the codec manually if your headphone model supports alternative options besides the standard SBC.
Is it safe to use the engineering menu to check Bluetooth?
Viewing information in the engineering menu is safe. The only danger is from changing parameters (calibration, transmitter tests), which can disrupt the operation of the radio module. Be careful and do not press buttons whose purpose you do not know.
