As many may know the BT4.1 spec is a little tricky as you can say a module or device is 4.1 compliant while only supporting some of the 4.1 features (you don't have to support them all). With that being said what specific BT4.1 features does the BCM4343w support? Most importantly in my endeavor, does it support simultaneous central and peripheral role actions?

Thanks in advance.

We use the BCM53128IQLE in unmanaged mode using the reference schematic BCM53128R_Eval_Schem. At power on, the LNK/ACT leds light for approx. 1 second and then turn off and then operate as expected when an Ethernet cable is plugged in (LED comes on when a cable is plugged in and blinks off when activity is detected). On some boards, a LNK/ACT led remains on after power on and then operates in reverse when a cable is plugged in - it goes off when a cable is plugged in and blinks on when activity is detected.

I assume that a power-on selftest operates and is showing something wrong, but I can't find anything in the data sheet that explains this. What is this LNK/ACT led indicating?

Regards.

Hi,

I am trying to find out wl and bl tools, but i am not able find it after building the image. Do i need to enable any MACRO's in Makefile or need to download it and integrate it into the build system. Please provide some information regarding this. Thanks in advance.

Hello vsb​

Based on your answers  provided in the other thread, for which I am thankful for, I have additional questions:

In the imx6ul-evk-btwifi.dtsi file, it mentions in the comments that

" This DTS file is written for plugging in Murata Wi-Fi/BT EVK into Slot * SD1 and using Murata i.MX InterConnect Ver 2.0 Adapter. Bluetooth UART & control signals are connected via ribbon cable (J1701 connector)."

However, I've noticed that the pin control for wlreg_on is gpio5_1 [MX6UL_PAD_SNVS_TAMPER1__GPIO5_IO01] which is not wired to imx6ul-EVK J1701.

1. Can you elaborate on how the 4343 WLREG_ON is controlled?
2. Is WL_HOST_WAKE requied for the bcmdhd driver.

Thanks in advance for your help.

Hello,

Can anyone provide the device tree source file (.dts) for imx6ul-14x14-evk-mv2.dtb or provide information as to where it can be found? It will be used with fsl-image-gui-x11-imx6ulevk.sdcard image, the bcmdhd driver and 4343W FW.

Thanks in advance for your help.

Hi,

Seems in POS applications everything lower than BLE4.2 is not allowed because of security issues.

I can’t find any info on how to disable only  the BLE part in the Murata module (based on BCM4343W).

Is this possible to have only Wifi and BT running without BLE active ?

Thanks
