Hi,

In the SMARC imx95 SOM, for the Wifi/BT MAYA-W260-00B chip was used. Currently we are facing the soft block enabled default in the both Wifi and BT. Previously, there is no issue in this but now we are facing the soft block issue. For the bluetooth, pairing is successful but we couldn’t send or receive the files, image and etc., Could you please help me on this issue?

Hi, I’m the Toradex AI Assistant.

I might make mistakes or occasionally get you wrong. Our support team will step in if needed.

I can help you troubleshoot the Wi-Fi and Bluetooth soft block issue on your SMARC iMX95 SoM. Before providing specific guidance, I need to clarify your setup to ensure I give you the most accurate instructions.

Could you please let me know:

  • Which OS and version are you running on the device?
  • Are you using Torizon OS, Yocto BSP, or another Linux distribution?

You can get this information by running the tdx-info command on your device. For more details about this tool, visit: Getting Device Information with Tdx-Info | Toradex Developer Center

Hardware Confirmation

I can confirm that the SMARC iMX95 does use the u-blox MAYA-W260-00B Wi-Fi/Bluetooth module based on the NXP IW611 chip (1). The module features Wi-Fi 6 802.11 dual-band and Bluetooth classic with full-featured Bluetooth Low Energy 5.4 (1).

Initial Troubleshooting Steps

Based on the Bluetooth documentation, here are some initial steps you can try:

Check and Unblock RF Kill

First, check if the Bluetooth hardware is blocked:

# rfkill list

(2)

If Bluetooth is soft blocked, unblock it:

# rfkill unblock bluetooth

(2)

Verify Bluetooth Service Status

Check if the BlueALSA service is running properly:

# systemctl status bluealsa.service

(2)

Once you provide the OS version information, I can give you more specific guidance for your platform configuration.

Common platforms include:

  • Hardware: Verdin i.MX8M Plus, Verdin AM62, Aquila AM69, Apalis i.MX8QP, Colibri i.MX8X, SMARC iMX95
  • OS: Yocto 7.2.0, Torizon 6.8.2, Torizon OS 6, BSP 7, BSP 6, Torizon OS 7.2.0-build.13

Best regards, Toradex AI Assistant.

Hello, Govindharajen.

As Toradex AI said, you can unblock the service using

# rfkill unblock bluetooth

if bluetooth is not unblocked, check if the systemctl service is running:

# systemctl status bluetooth.service

Best regards.

Hi egidio,

I’m asking that why the wifi and bluetooth is in block by default itself. In the old BSP images we haven’t face these issue but in the new BSP, we are facing this type of issue. Kindly clarify this and explain this. Thanks in advance.

Hello, Govindharajen.

After discussing with our team, we identified a problem indeed. Although the intended behavior is having the bluetooth soft-blocked by default, the configuration is not persisting between reboots.

We are currently investigating a solution for this.

Best regards,

Hello, Govindharajen. I’d like to update you that the team is tracking the bug internally.

To remedy the situation, you may create a file: /etc/modprobe.d/hci-uart.conf as a workaround, with the following content:

install hci_uart /sbin/modprobe mwifiex_sdio; sleep 2; /sbin/modprobe --ignore-install hci_uart

If you have further questions, let me know.
