I'm using a CYW43012 as part of Murata's LBEE59B1LV module. In our product, we need to reduce the transmit power of the CYW43012 to account for the antenna gain.

When using the Manufacturing Test firmware (wl0: Sep 1 2021 22:28:20 version 13.10.271.273 (9278a67 CY WLTEST) FWID 01-d304ce6e) , I can see that changes to maxp2ga0 and agbg0 are reflected in the output of running "wl curpower". When I perform an active scan using "iw", these settings do not seem to affect the output power of the device.

Details of the firmware, and the NVRAM dump:

# wl ver
wl0: Sep 1 2021 22:28:20 version 13.10.271.273 (9278a67 CY WLTEST) FWID 01-d304ce6e
# wl nvram_dump | grep -e "maxp2ga0" -e "agbg0"
agbg0=0x82
maxp2ga0=0x44

wl indicates that these changes are taking effect, e.g. the agbg0 setting is correctly being handled as a 2.5dB gain on the antenna:

# wl curpower | (head; tail -n 4)
Power Control: On, HW
Current Channel: 1
BSS Channel: 0/5
BSS Local Max: 0.0 dBm
BSS Local Constraint: 0.0 dB
Channel Width: 20MHz
User Target: 31.75 dBm
SROM Antgain 2G: 2.50 dB
SROM Antgain 5G: 0.0 dB
SAR: -32.0 dB
Maximum Power Target among all rates:15.50
Last est. power : 0.00
Power Target for the current rate :10.00
Last adjusted est. power : 0.00

 An example use of iw to scan in a specific channel (which we then observe using a spectrum analyzer)

# iw dev wlan0 scan freq 2412 > /dev/null

Expected behaviour:

Changing the antenna gain the NVRAM file (i.e. by adjusting  agbg0) will adjust the transmit power when performing an active scan.

Observed behaviour:

No change in transmit power.

Questions:

1. Is the contents of the CLM blob overriding these settings?
   1. If so, how can we adjust the CLM blob?

Dear Sir,

When I do iperf test, the error is shown.

After the error message is shown, we will not use "wl" command.

What is mean for " brcmf_proto_bcdc_query_dcmd: brcmf_proto_bcdc_msg failed w/status -110"?

The issue is not easy duplication.

Do you have any suggestions?

In the document AIROC-HCI-Firmware-Download.pdf, it states that the main ROM/Flash only  supports the 'Read memory', 'Write memory' and 'Launch' commands.

What are the supported commands in the minidriver?

• CRC32
• Baud change
• Chip erase

See: section 4.

The mini-driver image is 9kB on my platform, but I only need to perform a crc32 to determine if the image needs to be updated.   I think this can be implemented in <1kB, if it is not table driven.   Can I write my own code to run at the minidriver address, perform a CRC32, store the result and then return to the ROM code to read the result?

Hi,

I was trying to flash AIROC™ Bluetooth module CYBLE343072 Using FTDI USB-UART bridge while I tried to flash it showing the error 

Programming target device ...

Found serial port : COM43

Downloading FW ...
Failed to determine baud rate
Download failed

If the serial port was not detected, make sure no other program such as Client Control has the port open.

If you have issues downloading to the kit, follow the steps below:

Press and hold the 'Recover' button on the kit.
Press and hold the 'Reset' button on the kit.
Release the 'Reset' button.
After one second, release the 'Recover' button.

make: *** [../mtb_shared/core-make/release-v1.9.0/make/core/main.mk:434: secondstage_build] Error 2

Even though I tried recover reset method same error it getting. Can you suggest me to sort out this error.

Hi cypress team,

I am working on CYBT-343026 with SPP sample code. we'd like to improve SPP throughput, how can we tune the parameters within wiced_bt_l2cap_cfg_information_t based on SPP example code

Thanks

Does our Bluetooth stack support BLE Audio?

AoA,AoD ,our IC  support these? 

If not, when will it be supported,

Best  Regards,

Moon

Hi,

I initialize pUART like below:

wiced_set_debug_uart( WICED_ROUTE_DEBUG_NONE );
wiced_hal_puart_init();
wiced_hal_puart_select_uart_pads( PUART_RX_PIN, PUART_TX_PIN, 0, 0);

/* Set flow control */
wiced_hal_puart_flow_off();
/* BEGIN - puart interrupt */
wiced_hal_puart_reset_puart_interrupt();
wiced_hal_puart_register_interrupt(puart_rx_interrupt_callback);
/* Turn on Tx */
wiced_hal_puart_enable_tx();

it's work fine, but I am curious about is it possible to disablede-initialize) pUART Rx?

I find pUART Tx disable/enable , Rx enable API in wiced_hal_puart.h

, but no Rx disable.

thanks.

Hi,

 am trying to design a development board with a CYBT343072 module. I am trying to remove the need for a programmer on this board. So that the user could simply plug in a usb cable and be able to communicate with the chip and boot it. 

How can I use an FTDI usb to serial chip to do the programming? what are the steps i need to take change that in modustoolbox ide.
