Does The AX201 support Bluetooth coded PHY? This is the optional long-range feature of Bluetooth 5. In the product brief it says:
> Bluetooth® 5.2 provides 4x[6] range over Bluetooth® 4.2 using the same Tx power, enabling coverage throughout the home. Bluetooth® 5.2 also doubles data rate speed for faster transmissions, thereby reducing the overall power consumption[6]. Additionally, Bluetooth® 5.2 adds new, enhanced data broadcasting, enabling seamless location-based services and simpler pairing for Bluetooth® devices.
That little 6 after it says "4x" brings you to a note saying:
> Bluetooth® 5.2 Feature overview, https://www.bluetooth.com/wp-content/uploads/2020/01/Bluetooth_5.2_Feature_Overview.pdf. Only mandatory
features are supported.
LE Coded PHY is the feature that would provide the extra range. Page 27 of the linked Bluetooth overview says:
> Support for LE Coded is optional.
---
So now I'm confused. LE Coded is an optional Bluetooth feature and the AX201 only supports mandatory features. But the AX201 specification says that it provides 4x the range, but it cannot do that if it doesn't support Coded PHY.
So, does it support it or not?
If anyone in the community has an AX201 connected to a Linux machine, could you run the following command and let me know the output. I want to confirm before I make a purchase.
sudo btmgmt phy
For example, the output I get from a Bluetooth dongle that does support Coded PHY is (note the LECODEDTX and LECODEDRX)

Hello JolonBMT,
Thank you for posting in Intel community Forum.
For me to better understand and diagnose the issue further, let me ask you to provide detailed responses to the following questions. This information will help me isolate the problem and determine the most appropriate course of action moving forward.
- What is the brand and model of the system?
- May I know why are you asking for this feature? Can you further elaborate the use of the feature that you are asking?
- Did you manually install the AX201 on the system or is it embedded in the system?
If you have questions, please let us know. Thank you.
Best regards,

Hi Mike_Intel,
I don't really have a good answer to questions 1 and 3. The hardware may vary. I don't mind whether it comes preinstalled or needs to be installed manually. It'll definitely be running Linux (Ubuntu 24). The hardware depends on what can support coded PHY.
To answer question 2, I need a Bluetooth module that can support coded PHY so it is able to communicate with Bluetooth devices over a long distance (up to a few hundred metres). Coded PHY is an optional feature of Bluetooth 5+, so many devices don't support it. It may also be referred to as "S=8" or "125 kHz".
Coded PHY needs to be supported on both devices (central and peripheral). The AX201 would ideally be used as the central device with ublox NINA Bluetooth modules as the peripherals. The data being transmitted will be small packets of binary data (no audio streams). In the past, we've used a USB Bluetooth dongle, but with the move to new hardware, we want to see if we can have something installed inside the PC.
I hope this answers your questions. Thanks

Sorry, I don't understand. As I mentioned, I haven't purchased the hardware yet. I want to verify that the AX201 will be suitable for my needs. I have provided a Linux command in my original post that someone with the hardware can run to confirm the information I need
