Hello,

We are using 1YN - CYW43439 with CYW4343A2_001.003.016.0031.0000.1YN.hcd firmware. We are experiencing the following error when we connect multiple Android devices.

[DEL] Device 75:52:F2:2E:99:A8 Galaxy M33 5G

We tried the following but didn't help:

echo 0 > /sys/class/rfkill/rfkill0/state
echo 1 > /sys/class/rfkill/rfkill0/state

The problem is only solved when we reboot the system. Is there any other solution to this timeout problem such as reloading the device firmware? Can we force reload the firmware using `hcitool`?

Thanks for all the help!

Hi Team,

We are finding a way to backport Cypress 4373 wireless chip on hardware with USB interface on linux kernel 4.9, after compiling the drivers we get: compat.ko, cfg80211.ko, brcmutil.ko, brcmfmac.ko.

Then, we inserted all modules in sequence (compat.ko, cfg80211.ko,brcmutil.ko and brcmfmac.ko)and got the error "

brcmfmac: brcmf_fw_alloc_request: Unknown chip BCM57005/42"

Then we checked the source code and found out that it jumped to the timeout error here:

if (!brcmf_usb_ioctl_resp_wait(devinfo)) {
usb_kill_urb(devinfo->ctl_urb);
ret = -ETIMEDOUT;
} else {
memcpy(buffer, tmpbuf, buflen);

Hello,

I want to read the 1YN Bluetooth transmit power and write to it. How can I do this with the `hcitool`?

I'm using CYW4343A2_001.003.016.0031.0000.1YN.hcd firmware.

As far as I know CYW43439 has a maximum TX power of 8dB. If so is the following output wrong?

# hcitool -i hci0 cmd 0x08 0x004b
      LE Read Transmit Power (0x08|0x004b) ncmd 1
        Status: Success (0x00)
        Min Tx power: -16 dBm
        Max Tx power: 12 dBm
