Hi,

Our customer is working on software development with WICED 6.4.0 and will have BT SIG certification at the end of this March.

While preparing for BT SIG certification, the certification body noted the following.

>Reminder: Erratum 11838 testing is now mandatory for qualification.

>* Erratum 11838 was first qualifiable in TCRL 2019-1 and the qualification requirements became active on 20-Feb-2020.

Does WICED 6.4.0 include a fix of knob?

We were working on WICED host stack QDID 115853, but it's looks it not include a knob fix.

Regards,

Nagao.

Hi all:

    when I debug the LPN,I  have some doubts about LPN sleep times. the print messages as below:

before establishing the friendship with the friend node, the sleep timeout is 8s, after establishing the friendship, the sleep timeout is 6s

the device configuration info is below:

    .features           = WICED_BT_MESH_CORE_FEATURE_BIT_LOW_POWER, // A bit field indicating the device features. In Low Power mode no Relay, no Proxy and no Friend

    .friend_cfg         =                                           // Empty Configuration of the Friend Feature

    {

        .receive_window = 0,                                        // Receive Window value in milliseconds supported by the Friend node.

        .cache_buf_len  = 0,                                        // Length of the buffer for the cache

        .max_lpn_num    = 0                                         // Max number of Low Power Nodes with established friendship. Must be > 0 if Friend feature is supported.

    },

    .low_power          =                                           // Configuration of the Low Power Feature

    {

        .rssi_factor           = 2,                                 // contribution of the RSSI measured by the Friend node used in Friend Offer Delay calculations.

        .receive_window_factor = 2,                                 // contribution of the supported Receive Window used in Friend Offer Delay calculations.

        .min_cache_size_log    = 3,                                 // minimum number of messages that the Friend node can store in its Friend Cache.

        .receive_delay         = 100,                               // Receive delay in 1 ms units to be requested by the Low Power node.

        .poll_timeout          = 100                                // Poll timeout in 100ms units to be requested by the Low Power node.

    },

hope for correct reply as quickly as possible!

thanks!

I saw CYW920706 have an ADC interface,can this ADC be used as analog MIC input?

Another question is if I got an I2s interface Micphone，Can I connect it to CYW920706‘s I2s interface directly？

Hello Cypress Forums,

I am working with the CYBT-343026-01 module, and at the stage where we are seeking out FCC Test Labs, preferably in the Texas area. Does anyone have any recommendations for a good test lab(s) to contact? And what costs can we expect to see in testing for compliance with a module like the CYBT-343026-01?

Thank you,
Michael 

Can I program a CYBT-353027 Module installed in a CYBT-353027-PROG kit using the WICED-Studio application? I have used WICED-Studio to program a module on a CYBT-353027-EVAL board.

Alternatively is there a Linux version of the WICED_MOD_Prog tool?

hi  Cypress:

    does cybt-343026-01 support EFCOM , if it support and how to use it ?  can you provide the application note ?

I have got a CYBT-333047 eval-board and I'm using EZ-Serial via CySPP communication interface.

Now, I need a secured connection, where the user of the central device (a proprietary app) has to type in a random passkey which is generated by the CYBT-333047 module and shown at our display. So the user of the central device needs to have hardware access to couple with the module (peripheral). It mustn't be possible that anybody in the near can connect to our module without typeing in the right passkey. The passkey should be random or course.

I found the chapter Pairing with a Random Passkey (BLE) in EZ-Serial WICED Firmware Platform User Guide for CYW2070x-based Modules​ (p. 48 -49) and I hope, that this chapter describes my issue.

I tried this example but didn't get the expected results

hi   Cypress:

     when we try to connect with classical bt device ,   if  slave device want to connect with  password; how to use /BTC  command  to connect with other classical device ?

I downloaded EZ-Serial on the CYBT-353027-02 module of the CYBT-353027-EVAL Evaluation Board in order to build a Bluetooth/UART bridge with flow control enabled.

The EZ-Serial user manual highlights the following code (sent via USB/UART bridge) as the way to set up some parameters, such as baudrate, parity and flow control

STU,B=1C200,A=0,C=0,F=1,D=8,P=0,S=1

after sending this line using PuTTY the supposedly "success response" (as indicated by the manual) is given and appears as follows

@R,0009,STU,0000

Now the flow control is supposed to be enabled and the correspondent signal should be on GPIO_4 of the Evaluation Board but when I send data in both ways (UART->Bluetooth and Bluetooth->UART) the signal on GPIO_4 doesn't move at all (checked with an oscilloscope).

Am I doing anything wrong? Is there any way to make flow control work on PUART?

Thanks in advance

HI   CYPRESS:

       We can't find  gap_start_scan()  in CYBT-343026-01 user guide , please advice how we get the advertising bluetooth device  name with CYBT-343026-01?
