AIROC™ Bluetooth Forum Discussions

Hi, I am looking to use the CYBT-213043-MESH modules for bluetooth mesh. However, i can't find documentation on the current consumption of the modules in different power modes. May i know where i can find technical documentations for the module? Also how low can the current consumption be optimised for a typical low power node in a bluetooth mesh? What kind of settings do i need to do (ie low power mode sleep mode etc) to ensure the lowest possible current consumption for a low power node in order to run on battery for the longest duration?

Hi, 

We are using CYW20704UA2KFFB1G BT device on the VIP6102 Android platform (with BCM SoC 7271). We want to know if there has been any new updates to the firmware or drivers for this device in the recent past.? If so, please share the details on where it can be downloaded.

regards,

Hi, 

I want to interface my CYW20706  to a linear PCM codec device in slave mode.

I have been working with the CYW20706 for my intercom project for a while now. I have been able to use the sample HSP-Audio Gateway code using the Modulus ToolBox to initiate a connection with my Bluetooth headset.

I connected my CYW20706 to an I2S/PCM audio codec (Digilent Pmod I2S2) and I successfully managed to achieve the desired bidirectional audio communication. However, all along, the CYW20706 has been configured as the PCM master providing the required Serial clock/PCM_BCLK and Left-Right Clock/PCM_SYNC to the slave PCM audio codec.

I want to configure the CYW20706 in HFP-Audio Gateway as a PCM/I2S slave so that it can receive the PCM_BCLK and PCM_SYNC clocks from the PCM audio codec acting as the PCM master.

Hello

In our application, we're running CYBT343026-01 with EZ-Serial firmware.

It is our need to drive the system to test mode for testing purposes, but in the manual I cannot find any referenced operation that must be performed.

Do you have any hint / procedure to suggest?

Thanks a lot,

Best regards

Hi,

I want to configure my CYW20706 in HFP-Audio Gateway to produce 8K voice samples instead of the default 16K voice samples for my I2S/PCM audio codec.

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

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 , 

When 20706 as BLE peripheral, how to update connecnt parameter. I didn't find any API

because of HCI_ERR_INSTANT_PASSED (0x28) connect down event occur frequently, 

I want to update slave_latency when connect up.

and I also find  wiced_bt_ble_get_connection_parameters didn't work well, when using this API 20706 will pending and watch dog reset.

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 cypress team,

I am work on spp sample code with CYBT-343026. And I want to keep my 343026 in slave, but sometimes there's a role switch that my 343026 become master. I have tride wiced_bt_dev_switch_role to switch it back to slave but it doesn't  work. What can I do to keep it in slave mode.
