WICED Studio Bluetooth

Hello,

I have used the latest Firmware 1.2.27 (for CYBT-343026-01) below to verify the operation of BLE GAP Central.

https://www.cypress.com/documentation/software-and-drivers/ez-serial-ez-ble-module-firmware-platform

I refer to [3.5 GAP Central Examples] in the User Guide.

I have confirmed the operation of [Example 2: Start 5-second active scan with duplicate filtering enabled], but the scan response packet reports the same data as advertise.

@E,0062,S,R=00,A=EF00028B78FD,T=01,S=DB,B=00,D=020106110700A10C2000089A9EE21115A13333336507FF310100000000

@E,0062,S,R=04,A=EF00028B78FD,T=01,S=DA,B=00,D=020106110700A10C2000089A9EE21115A13333336507FF310100000000

For the environment we are checking, we have prepared two CYBT-343026-01. (One is Central, the other is Peripheral)

Since Factory reset (/ RFAC) is performed, the settings are in the initial state.

Are there any other settings you need?

Best regards,

TK

After "Set_Sleepmode_Param" to enter sleep mode,

Which hci command could get chip state or wake up the device to indicate whether it is operating normally in sleep mode?

CYW20706, BCM89071, etc.....

We're trying to build an HF audio gateway using CYW920706WCDEVAL and unmodified example software provided with WICED Studio 6.4 (WICED-SDK Version: Wiced_006.004.000.0061 / b38d42ee8368ff374b13514286120afd9e788a07), and we have troubles connecting AirPods to the evaluation board, and I think the WeSCO setting can be the reason for those. Comparing air traces for a mobile phone and CYW20706 I could see that "LMP eSCO Link Request" by the mobile phone is accepted by AirPods, while the request from our product is not answered at all. The only difference between those 2 requests is WeSCO - mobile phone sets it to 4, while CYBT sets it to 6.

When CYW920706 requests an eSCO link towards a headset (see code snippet below), it results in "LMP eSCO Link Request" for 2-EV3 packets where WeSCO parameter in is set to 6 slots. However, according to Bluetooth Core specs (Link Manager Protocol Specification, Table 5.3: Mandatory parameter ranges for eSCO packet types) this parameter for 2-EV3 packets shall be 0, 2 or 4.

Please advise, how to force WeSCO become 4 instead of 6.

wiced_bt_sco_params_t params;

params.use_wbs = WICED_TRUE;
params.max_latency = 13;
params.retrans_effort = BTM_ESCO_RETRANS_QUALITY;
params.packet_types = ( BTM_SCO_PKT_TYPES_MASK_EV3 | /* EV3 + 2-EV3 */
BTM_SCO_PKT_TYPES_MASK_NO_3_EV3 |
BTM_SCO_PKT_TYPES_MASK_NO_2_EV5 |
BTM_SCO_PKT_TYPES_MASK_NO_3_EV5 );

status = wiced_bt_sco_create_as_initiator(p_scb->hf_addr, &p_scb->sco_idx, &params);

Hi,

I am having trouble on getting 40KB/s throughput from module to my laptop. According to this thread ,  by @Owen_Zhang123 ,the module is capable of having a throughput of 65KB/s. I would like to know the test configurations used during the said and would like to have my test configuration the same for my testing.  

Thanks,

hi,

i have found the bonding status of pairing event is changed when device is connecting.

i want to know what is bonding status. it is different with "wiced_result_t"

where the mean of bonding status is in?

i want to know bonding status value it have same with structure as below.

typedef struct {
    uint8_t *bd_addr; /**< peer address */
    wiced_bt_transport_t transport; /**< BT_TRANSPORT_BR_EDR or BT_TRANSPORT_LE */
    wiced_bt_dev_pairing_info_t pairing_complete_info; /**< Transport dependent pairing complete infomation */
    wiced_result_t bonding_status; /**< current status of bonding process to notify app of completion status of storing keys */
} wiced_bt_dev_pairing_cplt_t;

thanks.

Hi,

I have a BLE sensor updating its manufacturer data to send the read values. This sensor is non-connectable and I'm trying to setup a CYBT-343026 to read the manuf data of the sensor and update a notify characteristic so the subscribed clients receive the data.

I've been looking for some examples inside the wiced github but weren't able to find anything useful.

Is the proposed solution possible? Or the chip is not able to change between observer and advertise?

Thanks in advance.

Hello, 

I am pretty new to Cypress boards. Is it possible to use bluekitchen/btstack with the CYW920819EVB-02 over UART? I see support for older boards but not this one.

Thanks.

Hi ,

We are using  CYW920721B2EVK-02 as a bluetooth device. We want to enter in to shutdown mode when there is no activity.

In callback sleep handle we are giving WICED_SLEEP_ALLOWED_WITH_SHUTDOWN. But from the traces we see it is not going to shutdown mode.

Can anyone help us how to enter shut down mode .

Thanks for your help in advance.

Thanks & Regards,

Krishna.
