Sona TI351 - Wi-Fi 6 + Bluetooth v5.4 Module

hciconfig has been deprecated and it is recommended to use bluetoothctl with BlueZ 5.x.

hcitool is limited to classic Bluetooth functionality. The Sona TI351 radio is BLE only and does not have support for classic Bluetooth.  

Both the Sona TI351 and the Ezurio 60 Series radios require a radio specific regulatory database. They cannot both be activated at the same time. Whichever driver loads first will work; the second to load will fail.

If you have a platform where both radios are present, you will need to blacklist the one you don’t need so the other will come up.

Note: co-located radios, where two radios are active at the same time, is not permitted under the Ezurio modular certification and is not tested or supported. Radio co-location requires additional testing and documentation to prove compliance, along with a Change Of ID.

The TI351 won’t connect to a smartphone unless the le resolver is explicitly enabled. This can be done using the hcitool with the command: hcitool -i hci0 lerlon

The Sona TI351 is configured to support a maximum of 16 clients in AP mode. Please note that the more clients associated, the more resources are taken up. This will cause performance degradation on all of the devices. 

Yes, there is a watchdog mechanism in the Sona TI351 that will detect an issue and reset the radio. To accomplish this, there needs to be GPIO control over the W_DISABLE# signal. This is typically implemented with a regulator construct in the device tree.

Please see the Sona TI Software Integration Guide for more information and a sample Device Tree.

Wake On Wireless is supported on the Sona TI351 Wi-Fi interface, however it requires that Out Of Band (GPIO) IRQ is used via the SDIO_WAKE#/HOST_IRQ_WL signal. Note that when using the M.2 1216 module this signal is active high (HOST_IRQ_WL), and when using the M.2 2230 module this signal is inverted on the carrier board (SDIO_WAKE#) to be active low for compliance with the M.2 specification.

Please see the Sona TI Software Integration Guide for more information and a sample Device Tree.

Yes, the Sona TI351 Bluetooth radio requires that the host must immediately stop transmitting when RTS is asserted. If even one byte is transmitted then the firmware will hang. You must disable the power saving “autonomous” mode before enabling the Bluetooth interface.

The Sona TI351 UART requires RTS/CTS hardware handshaking and operates at 115200 baud. In addition, the host must immediately stop transmitting when RTS is asserted. If the host sends even one byte after RTS is asserted the firmware will hang.

If this is a problem, then the host must disable the power saving “autonomous” mode before enabling the Bluetooth interface.

There is only one core on the Sona TI351 and it handles both Wi-Fi and Bluetooth. Bluetooth functionality must be enabled from user space through the ble_enable pseudofile in the Wi-Fi debugfs interface. For more information, please see the Runtime Validation section of the Sona TI Software Integration Guide

PM run time must be enabled on the SDIO interface for this driver as documented in the Software Integration guide. Ensure that the cap-power-off-card property is set in the mmc/sdio node used with the Sona TI351.

The SDIO interrupt can be either in-band or out of band. If Wake On Wireless is desired, then the interrupt must be out of band. The HOST_IRQ_WL signal on the cc3351 is the external interrupt signal. This is an active high signal from the cc3351 and is produced directly on the M.2 1216 module as HOST_IRQ_WL. This signal is inverted on the M.2 2230 carrier board for compliance with the M.2 specification and produced on the SDIO_WAKE# pin.

So if using the solder down M.2 1216 module, the OOB interrupt is HOST_IRQ_WL and is active high. If using the M.2 2230 plug in module the OOB interrupt is SDIO_WAKE# and is active low.

The pin should be configured as a LEVEL sensitive interrupt, not an EDGE sensitive interrupt. You may miss interrupts if configuring it for EDGE sensitive. Note that some processors do not support LEVEL interrupts, so SDIO in-band is the preferred option in this case.

Please see the Sona TI Software Integration Guide for more information and a sample Device Tree.

The SDIO_WAKE#/HOST_IRQ_WL signal is a SenseOnPower pin that must be low at the input to the cc3351 chip itself when the device is powered up. There is an internal pull-down on this signal, but the host platform must ensure it is not driven high before the Sona TI351 is powered up. If that cannot be guaranteed, this signal must be buffered.

This signal is the active high HOST_IRQ_WL signal when using the M.2 1216 module. It is inverted on the M.2 2230 carrier board and exposed as SDIO_WAKE# to make it active low for M.2 compliance. This issue does not apply to the M.2 2230 module variant because that inverter buffers the HOST_IRQ_WL signal from the host.

Please see the Sona TI Software Integration Guide for more information and a sample Device Tree.

The Sona MT320 uses SDIO 2.0 for Wi-Fi and HS-UART for Bluetooth.

The Sona MT320 is a 5.4 spec Single-Mode BLE radio. The primary Bluetooth features are:

• LE 2 Mbps PHY
• LE Long Range (LE-LR)
• UART baud rates upto 4 Mbps
• Advertising Extensions

An Ezurio Wi-Fi module can be configured for AP-Sta mode with the following nmcli commands:

• iw dev wlan0 interface add wlan1 type __ap
• nmcli con add con-name myap ifname wlan1 type wifi ssid myapssid autoconnect yes 802.11-wireless.mode ap ipv4.method shared
• nmcli con add con-name mysta ifname wlan0 type wifi ssid mystassid

This is assumes that you have the iw and dnsmasq packages installed in your build.

Note: In the above configuration, the Access Point will follow the channel that the station associates to. Therefore it is reccomended that the client is configured to use a 2.4 GHz channel or the U-NII-1 channels in the 5 GHz band as the Ezurio radios will not work as DFS masters and do not support AP mode in the rest for the 5 GHz channels nor in the 6 GHz band.>

Yes, If you decide to use NetworkManager, then systemd-networkd should be removed from the system. We would recommend changing Yocto systemd PACKAGECONFIG to not build it into image.

The Sona TI351 Wifi module only supports 20MHz wide Wi-Fi channels.

If your application requires wider Wi-Fi channels, please refer to Ezurios Wi-Fi Modules

Yes, the Sona-TI351 requires a 32.768 kHz signal to function.

That signal can be generated internally by the chip-set itself by leaving the SUSCLK / SLOW_CLK_IN pin unconnected. This comes with the benefit of having less components on the PCB. But also comes with the caveat of being less accurate and more power consuming compared to sourcing that signal externally.

For optimal power consumption, the slow clock can be generated externally by an oscillator or sourced from
elsewhere in the system, e.g. a GPIO from the host processor.

The external source must meet the requirements shown in below table and must be be fed into the SUSCLK / SLOW_CLK_IN pin and must be stable before nReset is de-asserted and device is enabled.

External Slow Clock Requirements

The Sona TI351 Wifi module only supports Bluetooth Low Energy (BLE).
